One developer, a lot of PDFs

Who is behind this

This site is run by one person. There is no company behind it, no team, no funding round — just a developer who got tired of online PDF converters that upload your contract to an unknown server and then ask you to sign up before letting you download it.

I build tools with AI assistance and document the process: what works, what quietly fails, how to handle payment, hosting, translation, analytics and advertising when your users are spread across a dozen countries. This site is one of those projects, and its source of truth is the same as everything else I write — what actually shipped.

What this site does

PDF Toolkit collects nineteen everyday PDF jobs — merge, split, rotate, delete, reorder, compress, unlock, watermark, page numbers, PDF-to-image, image-to-PDF, Word-to-PDF, QR codes, text comparison and favicon building — into one place. Every one of them runs entirely inside your browser.

That single design decision drives everything else. Because there is no server-side processing, there is nothing to sign up for, no file size tier to pay for, no queue, and no copy of your document sitting on someone else's disk. It also means the tools keep working on a train, on a locked-down corporate laptop, or after the site has been unplugged from the network.

Who it is for

People who handle a handful of documents a week and do not want to install a 400 MB desktop suite for it: freelancers assembling client packs, students merging lecture slides, office workers who need a signature page removed before a deadline, anyone who has to send a scanned form that is 40 MB too large for an email attachment.

If you are dealing with thousands of documents a day, you want a command-line tool or an API, not a web page. This is deliberately built for the occasional, urgent, one-off job.
