About

Most free converters are a maze of three adverts shaped like download buttons, a countdown, a watermark, and a sign-up wall at the file size you actually have. They work, eventually. This is an attempt at the version that just does the thing.

How it is built

The site is React and Tailwind, prerendered to static HTML so a page arrives complete rather than as a blank shell waiting for JavaScript.

The conversion service behind the PDF tools is written in DexLang, a statically typed language that compiles to C, and it orchestrates qpdf, Ghostscript, poppler and img2pdf. It holds nothing but a scratch directory it empties on a timer.

What is coming

More tools, roughly in the order people look for them. PDF to Word is the one everyone asks for and the one worth doing properly rather than quickly. A PDF records where marks were drawn, not what they mean, so getting columns and tables back out is the entire problem.
