I was working on this tool for over a year and made a PDF editor from scratch. You can edit existing text, redact, annotate, fill forms, and I made it run fully locally so you don't have to deal with signups and upload rates. You can try it at https://keypdf.net

If you deal with font convertion on daily basis feel free to try my open source font utility it works locally and has rare features such as type1 fonts support and convering batch from zip files, it is compeltly free you can look at the code anytime or self host it or try at keypdf.net/keyfont

https://github.com/KeyPDF/KeyFont this is github repo.

I made KeyPDF.net and recently added OCR, but now it can also edit scanned text by reconstructing the font from the image, feel free to try it and let me know if there are any issues since there is lots of work to do.

I spent over 14 months writing a PDF engine from scratch, and you can see how it works above first couple of months I spent thinking about architecture, then I slowly added support to most of the font encodings, then added vector graphic support, and finally brought images, and after around half a year of debugging and building complex features like redaction of text I am pretty much done and launching a beta you can try at keypdf.net

Unlike most of the PDF editors in the browser, mine can edit text, while others can only annotate or require server uploads with rate limits, so feel free to try KeyPDF

Unlike most of the local tools, mine was built from scratch and can edit PDF files like an actual professional editor works locally and in the browser its free.

Hello guys so as a student I have to deal with many assignments and files in many different formats but PDF files are pretty hard to handle in terms of editing because most of the desktop apps are not an option for ChromeOS as they offer annotations and signing and not true text ending so I have been working for over a year on making PDF editor from scratch that runs locally In browser that is free and doesn't require any signups so if you need to edit PDF file existing text or images feel free to try keypdf.net thanks

Hello Reddit, so as it is said in a title, I made a PDF editor from scratch after a frustration I got when I needed to edit some simple PDF file and found out that my only option was heavy desktop apps for a $100+/year subscription or scammy sites with mostly fake promises like "REAL PDF EDITING" when in fact the so-called editing was just annotations. I started in spring 2025 and thought it was light work, and boy, was I wrong. It turns out it's all complicated, and existing tools are not matching my goal to edit PDF files on client side in browser, so I had to build my own. I started making a new PDF engine and expanding it, read hundreds of pages of documentation, and solved uncountable numbers of bugs, so today I would like you to try the first public version of KeyPDF, a brand new browser PDF editor.
