8 Reliable Online PDF Editors You Can Use for Free

Last updated on Aug 5, 2026

Unlike other document formats, say DOCX or ODT which are basically raw formats, a PDF formatted file is created for a final use and not to edit.

However, if you have to do it (editing PDF file), there are some tools you can use. Including the ones that are available on the internet.

Taking advantage of online tools like PDF editors gives you so many advantages. The most prominent one is that you don't have to flood your computer with too many apps you don't even frequently use them.

An online PDF editor works by turning your PDF files into raw files. Well, not fully raw since most online PDF editors only enable you to add additional elements to your PDF files like additional texts, image to hand write.

Here is the list of online PDF editor tools which you can use to edit your PDF files.

1. ProPDF

ProPDF is a great online PDF editor that you can use for free. You can use it to edit a PDF file instantly without needing to login. You just need to select the PDF file that you want to edit and upload and ProPDF will load its editor, which has a clean interface.

ProPDF offers an ad-free PDF editing experience even if you are on the free plan.

There are a lot of things you can do with this tool. From editing the existing texts on your PDF file, adding a new text, adding a signature, adding images, adding shapes, and so on.

You can even insert a new page on your PDF document and then populate it with text and other elements.

Once done editing a PDF file, you can re-download your document in a PDF format or store it to cloud storage services like Dropbox, Google Drive and OneDrive.

Apart from PDF editor (which you can use to edit a PDF file), ProPDF also comes with PDF converter which you can use to convert a PDF file into Word, ODT, PPT, XLS, and so on.

2. Sejda

Without any intention of underestimating other tools, Sejda is probably the best online PDF editor. This tool will truly turn your PDF files into a raw file where you can do nearly everything regarding the PDF editing.

From replacing the texts, adding new texts, inserting images and signature, adding some annotations, covering certain text with a whiteout and lots more.

Sejda itself is an online tool that helps you do some PDF-related tasks. Apart from editing (as mentioned in the paragraph above) you can also do such other tasks to your PDF files as extracting PDF, splitting, merging, cropping and many other more.

At the time of writing you don't have to create any account to start editing PDF.

3. PDFescape

PDFescape is also a great tool you can use to edit your PDF files. Unfortunately, you won't be able to replace the existing texts with the new ones directly like you can do with Sejda. But you can outsmart it by blocking a certain text you want to replace with a whiteout and add new text over it.

Yes, inserting new texts is one of the capabilities of PDFescape as well as other tasks including inserting images or links, adding hand write for signature, annotation and more.

This online PDF editor also doesn't require you to create an account to use its service but, there are several benefits you will get if you create an account. Including the ability to share your edited PDF directly online.

4. PDF Pro

Same as PDFescape, PDF Pro is also unable to directly replace the existing texts with the new ones.  If you want to do it you need to erase the text you want to replace using its whiteout feature and typing the new text on it.

One of the appealing things of PDF Pro is that it comes with a handy file manager which allows you to access the PDF files you have edited before. You will also be able to share your edited PDFs via email but an account is required before being able to do this. There is also an option to directly print your PDF.

The overall features of this online PDF editor are quite similar to two previous PDF editors which enable you to add such elements as drawings, signature, images, and lots more.

5. Smallpdf

Smallpdf is a bit similar to Sejda. They both provide several tools to enable you to do some PDF-related tasks, including editing. The difference is, Smallpdf has fewer features than Sejda. This online PDF editor doesn't turn your PDF files into a raw file so you can't replace the existing texts directly. There is even no whiteout feature.

Fortunately, there is an "add shape" feature with the color you can customize so you can cover a certain text with a white block and add new text over it.

Smallpdf has a very clean interface which is very nice looking. Another appealing thing about this online PDF editor is that you can import existing PDF files you have on either your Google Drive or Dropbox account.

6. PDFzorro

PDFzorro is another option of online PDF editor you can use if you need to edit your PDF files. There is no really unique feature of this tool. It has common features like previous tools. With this tool you can do such things as adding lines, highlighting specific text, adding rectangle shape to erase certain text.

The last mentioned is useful if you need to replace certain text in your PDF file since you won't be able to directly delete existing texts like you can do with Sejda. PDFzorro also doesn't require you to have an account so you can immediately use this tool without bothering to create an account.

7. PDF2Go

There are some similarities between PDF2Go and Smallpdf. They both have a colorful interface in the front page of their website. They also provide several tools you can use to do such things as edit the content of your PDF files, merging two or more PDF files, compressing, converting and lots more.

The overall features of this online PDF editor are not far different to other tools in this list. The downside of this tool is that its editor interface looks too small. Plus, you also need to click manually each of the pages you want to edit.

The good side is, PDF2Go has supported cloud storage so you can import your existing PDF files on both Dropbox and Google Drive. You can also load PDF files from URLs.

8. FormSwift

Instead of offering too many features, FormSwift has only four basic menus consisting of Text, Erase, Image and Signature. Without a long explanation you have known what to do with those menus.

If your purpose of editing a PDF file is to fix some typos you can take advantage of the Erase menu to erase certain text and replace it with the right typing. FormSwift also makes it possible if you want to send the edited PDF directly via email. But, you need to create an account to do it.

There are actually several other online PDF editor tools available on the internet wilderness but, the 7 tools above are the most reliable ones. If you have more items just add them in the comment section below.
