About us
Small, fast web tools that do their work inside your browser, built by an independent team.
What PieToolkit is
PieToolkit is a set of free web tools for everyday file jobs: turning photos into a PDF, editing the text inside a PDF, converting images between WebP, AVIF, PNG and JPG, checking whether a website is up, decoding a token. There are 19 tools on the site today, and more go live as they are ready.
Every tool has the same shape. You open the page, add your file or paste your text, press one button and get the result. There is no account, no queue, no watermark and no paid tier.
What makes it different
Most online converters work by uploading your file to a server, processing it there and sending the result back. PieToolkit does the opposite. The conversion engine is downloaded to your browser as WebAssembly, and your file is read straight from your disk into a background thread on your own device. No network request ever carries your data. You can read the details on the how it works page.
The engines are the same libraries that desktop software uses, compiled to run in the browser:
- The PDF editor runs PDFium, the PDF engine inside Chrome, so it reads what Chrome reads.
- The image converters run libwebp, libavif, mozjpeg and oxipng, well-known open source encoders, so a WebP made here matches one made by the format's own tools.
The difference shows in three practical ways. A set of photos becomes a PDF in the time your device takes to decode them, because there is no upload and no download of the result. The tools keep working on a slow or patchy connection once the page has loaded. And the only size limit is your device's memory, not our server's patience.
How the site is paid for
PieToolkit shows advertising from Google AdSense. Ads sit below the tools and between sections of text, never over a tool, never where they could push it down the page. Nothing on the site is locked behind a payment.
We also keep two running counts, which you can see above the footer: how many files the tools have processed and how large they were in total. They are plain numbers counted on our servers. The files themselves never reach us. The privacy policy lists everything else we collect, which is short.
Who makes it
PieToolkit is an independent project that started in 2026. It is built and run by a small team that writes the tools, tests them on real files and answers the mail. There is no larger company behind it, so the people who decide what gets built are the people who use it.
The library behind each tool is chosen for quality first, in whatever language it was written, and then compiled to WebAssembly. Each choice, and the alternatives that lost, is written down before the tool is built.
Get in touch
Bug reports and tool requests are the most useful mail we get. The contact page has the addresses and a form, and the all tools page shows everything that is live today.
