PDF is notoriously difficult to edit, which is why the best thing to do if you want to change a huge portion of the document would be to convert the file to an editable format like Word. But with the right tool, you may still be able to write on a PDF and alter the text.
These tools are however very few and finding a reliable PDF writer online can be very hard. After testing a few, the following 5 tools can help depending on what you want to write over the PDF. This article also introduces a PDF writer on desktop - UPDF.
The Ultimate List of Top 5 Free PDF Writers Online
1. iLovePDF
If your goal is to edit all aspects of the document, particularly the text iLovePDF is a good choice. Although it is deployed completely online, this is one of the most complete online PDF writers you will find. You can use it to add and remove text from the document and even select large blocks of text to change the font and color of the text.

If you want to write over the text that is already on the PDF, iLovePDF also offers you a wide range of annotation tools designed for that purpose. You can add comments, highlight the text, underline text for emphasis, and even add notes. It also has a lot of other PDF editing tools such as the ability to convert, merge, split, and compress PDF files.
2. Soda PDF
We have included Soda PDF on this list, not only because it is perhaps the easiest online PDF writer that you will find on the market, but also for the sheer number of editing tools that it has. It allows you to make changes to the text and pages on the document in significant ways. The simple user interface allows you to simply click on an area on the document and type in the text you'd like to add.

It is also one of the best ways to make changes to the images on your document, including being able to crop the images already on the page or move them to a separate section of the document. Soda PDF can also be used to convert PDFs to other formats.
3. PDF2GO
PDF2GO is one of the best ways to make small changes to a PDF document. When it comes to editing text, it will not offer you too many options, but it may be the best way to go into the document and add a missing word here and there. One of the main reasons we think this tool deserves a mention is that it is so easy to use. Uploading the document to it is as simple as dragging and dropping the file into the main program.

But PDF2GO can do so much more than just add and remove text. You can use it to add a password to the document, add a valid signature to the document and even compress, split, and merge PDFs. It may however not be useful if you want to convert PDFs to other formats.

It is also one of the best ways to create and convert PDFs to a variety of other formats. But unlike other online tools, Docfly is not a free program.
