How to save ink with Grayscale PDF

20 / 5 / 2019

When grayscale comes to mind, it has become a standard to automatically think that its black and white. This is correct in some terms but not entirely true when it comes to printing or photo editing. Indeed, grayscale is the product of a black and white image, the absence of color on a photo or document. To convert a file in grayscale means to remove the colors and leave black as its main source of ink. The importance of grayscale is gravely high for those looking into saving ink and money. But is grayscale really different from black and white?


The difference between black and white printing V.S. grayscale printing

Quite confused why you need to print your files into grayscale instead of black and white? If you’re not familiar yet with how and why these two are different. Here’s a quick comparison on what these two really are and what are the pros and cons of having these color settings on your PDF files.

In a gist, black and white, also known as monochrome, only has two colors – black ink and white, which basically means no ink at all. When you print a photo or text in this setting, the characters are printed out as black and the unprinted background remains white. This setting often produces and release more black colors, forcing a darker character, and darker silhouettes. While the printing is crisp on text, photos aren’t always produced the same as compared to its colored version due to the fact that shades are completely forgotten in black and white. Though photos are not its strongest suit, printing texts in black and white are often recommended to create a document that is easier to read.

On the other hand, Grayscale contains shades of grey – a lighter and mix of black and white or perhaps in printer language, it uses less black ink than the previous setting. When you zoom in to laser or inkjet printers, print patterns in microscopic dots are created to produce shades. Since grayscale creates different shades and variation of gray tones, photos are often produced similar to it's actual and closely accurate to the photograph, therefore, becomes the second choice to reproducing images.

How to split PDF for free

16 / 5 / 2019

Splitting a PDF file may be a little tricky because we all have different requirements on how we should do it. There are different ways to split. You can split PDF by pages, split PDF by bookmarks, split PDF pages in half, split by size and split by text.

deftpdf split pdf pages in three ways

Tools for Splitting PDF by Pages

There are three simple tools you can use for splitting PDF – your browser, online pdf splitter DeftPDF and your Microsoft Word. The first two tools can split any sorts of PDF including scanned PDF files. The last tool, however, can only be used for PDF documents that were previously a .DOC, .XLSX, or .PPT files. Though all ways will be shown, please take in consideration that not all will be able to split according to all kinds of splitting requirements. The method to be shown here is splitting only by pages. If you want to split your PDF by size, text, bookmarks, or in half, you can always use DeftPDF for free to do all these.


Splitting PDF with your Browser

Your browser can be your free tool for reading your PDF documents and it can also be your printing tool. In our previous blog posts, we’ve shown you how to use your browser to extract and this will actually be similar to splitting your PDF pages. So how do you do it?

Step two: Click the “options” or settings menu on your browser and click “Print

Step three:  Set your destination to “Save as PDF" instead of placing your printer.

deftpdf save as pdf in browser

Step four: Modify the “Pages” to “Custom” and input the pages you wish to split then save your new PDF files.

For example, you have 8 pages on your PDF file.  You need to split it in pages 1-4 and 5-8. Simply input 1-4 on the custom pages and save your file, then on the next procedure, input pages 5-8 then save again. This will give you two sets of PDFs with the pages you need to be together.

This method is also manually done so if you’re not patient and you want something that involves only a few clicks of your time, maybe you ought to try other methods instead. You can try to split PDF online with free tools of DeftPDF or purchase other software available. So here is how you do it with Microsoft:

3 Easy ways how to create fillable forms

13 / 5 / 2019

There are more than two ways to create a fillable form. You can create it from Microsoft Word, Excel, PowerPoint, using online designer tools and readymade forms like Google forms or JotForm, or creating fillable PDF using PDF editor online such as DeftPDF. Here, we will show you 3 different ways on how you can do this easily without paying anything! Let’s start with the offline way – using Microsoft applications.


Creating fillable Microsoft Word forms

Not everybody knows this but you can do so much more with Microsoft Word other than typing and encoding. You see, there’s another tab available that isn’t enabled by everybody on the word application and it’s called the “Developer tool” which can actually allow you to add forms, restrict editing and help you design better. Don’t worry, you don’t need to purchase or add more extensions! You just need to activate it with these simple steps:

Step one: Activate the developer tool by clicking “File” from the menu then click “Options.

Micrososft Word Opening Developer_Deftpdf

Step two: On the selection on the left row, click “Customize Ribbon” and tick the box of the “Developer tools” to activate and show its properties on the word application.

Microsoft developer tool_deftpdf

Step three: You will now be able to see the new tab on your Word application – “Developer”

Deftpdf_Micrososft developer

Step four: Now the first thing you need to do is to create your form by encoding all the details you need and the questions you want to include. Design it the way you want the form to appear. You may also use the form templates available from your Microsoft word which can be found when you click “File” then click “new” and search for online templates.


Step five: After encoding your form, protect your it first by clicking “Developer” then click “Restrict Editing.” This will limit the receiver of your form from editing or deleting the questions on your form.

Microsoft developer tool_deftpdf tools

Step six: Add form fields that your audience can fill by clicking “Plain text content control” and place it in the area where your receiver should input their answers. You can also add dropdown lists, checkboxes, images, and more.

plain text_Deftpdf

Step seven: After all the editing, click “SAVE” and the form will be ready for distribution as a Microsoft word document.

Quick tip: You can also turn this into a PDF form by saving this as a PDF file then you can use online free PDF editing tool, DeftPDF, to add your text boxes and making it fillable.


Creating a fillable PDF form

Though using Microsoft Word application is quite easy, the downside of saving it as a .DOC form becomes a dilemma due to its format. Since .DOC files are actually editable, the format can change depending on the user. Any special fonts used that isn’t a default font on the application or isn’t installed on the receiver’s computer may become deformed upon receiving it and may affect the layout, alignment and its overall appearance. This will also result in confusion for your receiver, giving them a hard time to fill out the form you sent. So, what better way to create a fillable form? We suggest you can create a PDF file format.

Creating a fillable PDF form isn’t as hard as it looks, in fact, it’s the easiest way and it can be free – if you’re using DeftPDF! Here’s an easy step by step guide on how to create your PDF form online:

Step one: Go to and click “Start Editing” on the homepage.

deftpdf_start editing

Step two: PDF editor online will appear and prompt you to upload a document but to create a new form, click “start with a new document” under the upload button.

deftpdf_start with a blank document

Step three: The site will give you a blank paper to start with. You can write your texts, add images, add shapes, links, and forms by clicking its respective buttons on the editing tool menu. Add all necessary elements as you prefer. Make sure to add your “forms fields” as a text box for your readers. This is where the receiver will fill out their answers. You may also add checkboxes, dropdown lists, bullets, and x marks.

deftpdf_create template

Step four: Once done with your new form, click “Apply changes” then “Download” to save the file to your computer.

If you’ve placed your forms right, your form will look like this and enable your receivers to add their answers on the form without any editing tools.

Creating a fillable form using online forms

If the form doesn’t need to be saved on the computer and you just need something online for your polls or surveys, you can probably try using online forms. This is also easy to use but the downside here is the fact that you can’t save it as an offline form and you can’t attach it in an email. You can probably send the link but it remains online and receivers will also need to be online even if they are just filling it out. Another note to consider is the fact that not all forms online are unlimited to use and free. If it’s free, there’s a limitation to its features and sometimes it only allows a certain number of answers.

There are thousands of online forms available such as Jotform, SurveyMonkey, FormSIte and many more but for the sake of our little demonstration in this article, we will use the most common one – Google forms. Here’s how to create your own online form:

Step one: Log in to your Gmail or Google Drive account

Step two: While you’re signed in, go to

Google forms_deftpdf demonstration

Step three: Choose a template you will use or create a new form with a blank document by clicking its respective thumbnail.

Step four:  Add the title of the form, description questions, and select the type of answer. You can add as many form fields, questions, photos, videos, texts and sections as you like. Just click the symbols on the right to add more elements. You can also edit the color and theme of the form.

Google forms add question

Step five: Once done modifying the form, click “Send” found at the top right of the page. This will give you three options – send it by email, get a link or embed it on your website. Your form and the responses from your readers will be saved automatically on your google drive.


Best recommended way to fillable forms

All three fillable forms are easy and free, it’s just up to you which one you think best fits your needs. We recommend you stay with a PDF format to create your form – its easy, its free, secure, reliable and you can fill it out online or offline. You can try using it online with DeftPDF tools and there are no limits in using the site. You can also do so much more such as protecting, unlocking, translating, cropping, compressing, resizing and many more.


How to annotate PDF pages using Adobe or DeftPDF

09 / 5 / 2019

Annotating is the act of adding text highlights to a document, noting those edit worthy phrases to correct its source. It is also the act of commenting on the file, which is usually used for contracts, thesis papers or writing. The act of annotating does not necessarily mean it will be edited as it only points out what should be deleted, inserted or changed. It is often seen as a highlight, a strikethrough text or sometimes a note is placed beside a phrase or a word.

Annotating on Word documents are easy as they are readily available on its application. PDF files, on the other hand, cannot be annotated with the same program, instead, we use its own PDF editor tool to make these notes possible. In this case, we will use Adobe Acrobat offline and DeftPDF to achieve the goal of annotating the PDF file while comparing both on its use.

DeftPDF annotating in word application

What are the annotations used and what does it mean?

There are only three types of basic annotations – highlight, strikethrough text, and notes. We use strikethrough on words to mark it and indicate that the text needs to be deleted. Highlighting the text, on the other hand, may be used to emphasize or add comments on it. Notes can also be added as a comment or as a memo to the source, to provide more information, give a meaningful remark to improve or sometimes it’s a note to compliment it. Other annotations that are usually used in writing also include inserting text, replace text, and delete text markups.


What are the pros and cons of using Adobe V.S. DeftPDF?

While both software provides the same tools, it is essential to understand its differences. For instance, if you are looking into connectivity, DeftPDF is edited and annotated online, which means you can directly send your final work after or upload it to online storage directly. Adobe acrobat meanwhile is used offline.

Installations and Subscriptions: With regards to installations, DeftPDF does not require users to install anything. You just simply go to the online website and use the tools right away. There is an option to install a chrome extension for more accessibility on future document editing but it’s not required. Adobe Acrobat meanwhile, needs to be downloaded and installed before using it offline.

Payment and Fees: In terms of payment, subscriptions or fees, DeftPDF does not require any. Not even information of the user to use the tools. Signing in is an option provided but not required. In fact, all of its tools are completely free to use. Adobe Acrobat’s free download version offers its basic annotation tool for free too but you need to subscribe to be able to use all its other editing features.

Saving your File: When it comes to saving your annotated work, minor differences can be evident. Since DeftPDF is online, it will not delete or write over the original PDF file, instead, it will create and save a new document upon downloading the file. Adobe acrobat meanwhile, will offer you both ways – to save the existing file with the annotation or to “save as” to create a new document so that the original file will stay the same.

Security and Safety of documents: Lastly, the most important question here is the security and safety of the file. DeftPDF ensures that the file you will edit is uploaded in an encrypted server, which means that your files are completely secure online. DeftPDF also guarantees that the files are deleted permanently after processing, therefore NO ONE will be able to get a copy of your file. Adobe Acrobat is used offline and can also be secure since the connection is only between the downloaded software and your computer. Both are secure and safe.


How do I annotate in Adobe Acrobat?

Annotating in Acrobat is actually pretty simple on its free basic version. You simply highlight PDF text using your cursor, right click on the highlighted field then select which kind annotation should be done with the choices that will appear.

You can change the color of your highlight by right-clicking on the highlighted text, choose properties then change the color as you prefer.

When you add notes as comments to the text, there is an option to view all comments on all notes. You can reveal all these by right-clicking on one of the highlighted texts, then select “open all pop-ups” or “show comment app.”

These are just a few of the annotation features that you can do in Adobe. Of course, if the PDF file has been saved with limited access and commenting is not allowed, these tools cannot be used on it unless the restrictions are lifted.


How do I annotate in DeftPDF?

DeftPDF is an online tool that is very easy to use and there are only a few steps to follow to annotating your PDF file.

Step one: Go to DeftPDF online and select the “Edit” tool from the menu

Step four: Highlight PDF text or strikethrough text on the document by moving your cursor over to the text area. A comment section will appear upon highlighting for you to add notes on the text.

Step five: Click “Apply changes” and save your work on your computer by clicking “Download.”

There are also other editing tools you can use that come handy for your PDF file and it already appears right in its editing tool menu and if you prefer to send the document right after annotating, you can also do this by selecting “Share” instead of “Download” after applying changes. You can also save it in your Google Drive or Dropbox if needed.
