About PDF365
PDF365 is a set of free PDF tools that work inside your browser. We built it because merging two files or signing a form shouldn’t mean uploading your documents to someone else’s server.
Who’s behind it
PDF365 is built and run by Shipra, a small independent software developer in Mildenhall, Suffolk. The website went live in 2026. It’s a small operation.
We write the tools, the help pages and the guides ourselves. Before a tool goes live we run it against a set of awkward test PDFs. Some use unusual fonts or Japanese and Arabic text; others have rotated pages or big photo scans, and a few are deliberately broken or password-protected. Then we check the output opens properly in more than one PDF reader. You can reach us through the contact page.
What you can do here
There are 25 tools at the moment, covering the jobs people do most: merging and splitting files, making them smaller, turning pages into images and back, signing, numbering pages, and adding or removing passwords. They work on a laptop, tablet or phone, and you don’t need an account.
Why the tools run in your browser
Uploading is convenient, but it means copies of contracts and payslips pass through other people’s computers. For most PDF jobs it isn’t necessary any more, because the browser you’re reading this in can merge, compress, encrypt and redraw pages perfectly well on its own, often faster than a round trip to a server would take.
So when you open a tool, your browser downloads the software and your file is processed on your own device. The heavy lifting is done by well-known open-source projects: pdf-lib for editing, Mozilla’s PDF.js for drawing pages, and qpdf for encryption.
How we try to work
If a tool has a limit, its page says so. Merge doesn’t keep bookmarks, for instance, and Greyscale turns pages into images. We tell you that up front rather than letting you find out later. Tools we haven’t finished, like Word to PDF, sit on the roadmap marked Planned instead of appearing as buttons that half work.
We also want the site to be usable without a mouse. Everything can be done with a keyboard, and our accessibility statement lists what still needs improving.
How it’s paid for
The tools are free. To cover hosting we plan to show a small number of labelled ads in the articles and around the pages. They’ll never appear inside a tool, next to a download button, or while a file is being processed. Right now there are no ads at all.

Found a bug, or want a tool we don’t have? Tell us. Office conversions and OCR for scanned documents are the most requested so far, and they’re next on the roadmap.
