Tools that work without taking your files
Convert a photo, shrink a video, build an invoice. Everything runs inside your own browser — so nothing is uploaded, nothing is stored, and nothing asks you to sign up.
The tools
Three today, more each week. Each one does a single job properly.
HEIC to JPG
Turn iPhone photos into JPG, PNG or WebP that opens anywhere. Batch supported.
Compress Video
Shrink a clip until it fits WhatsApp, email or Discord. Pick the destination, not a bitrate.
Invoice Generator
Fill it in, download the PDF. No account at any point, including the download.
Passport Photo
Official size for 20 countries, plus a printable sheet of six.
Why "on device" matters
Almost every free file tool online works by taking your file first. These don't, and that changes several things at once.
Your file stays yours
Bank statements, passport scans, client contracts, family photos. None of it is transmitted, because there is no server doing the work.
No upload wait
Work starts the instant you drop the file in. On a big file that alone can save several minutes.
No account, ever
Other tools gate the download because each file costs them server time. Ours cost nothing to run, so there is nothing to gate.
Works offline
Load a tool page, disconnect from the internet, and it still works. That is the simplest proof that nothing is being sent.
How it's possible to do this in a browser
For most of the web's history, anything demanding — converting a photo format, re-encoding a video, building a PDF — had to happen on a server. Browsers simply were not fast enough, and the code to do it did not exist in a form they could run.
That changed with WebAssembly, a way of running compiled programs at close to native speed inside a web page. The same decoders and encoders that power desktop software can now be compiled to run in a browser tab. A video encoder, an image decoder, a PDF writer — all of it fits in a page and runs on your own processor.
The practical effect is that the economics flip. A conventional online converter pays for bandwidth and processing on every single file, which is why it caps your file size, limits your daily conversions and asks you to create an account it can eventually charge. When the work happens on your machine instead, those costs are zero, and so are the reasons to restrict you.
There are genuine trade-offs, and it would be dishonest to skip them. Browser tabs have a memory ceiling, so very large files can fail. Encoding cannot use your graphics card, so it runs slower than a desktop program. Every tool here states its limits up front rather than letting you discover them halfway through.
For everything that fits inside those limits — which is the overwhelming majority of everyday tasks — doing the work locally is faster, more private, and free of the small indignities that come with the alternative.
