Why this site is built the way it is
Your file never leaves your device
Image and PDF tools use Canvas and WebAssembly in your own browser. There is no upload, no queue, no temporary copy on a server and nothing to delete afterwards. Open your Network tab and watch it stay quiet.
No sign-up, no drip-feed limits
No "3 free conversions per day", no email wall before the download button, no watermark on the output. Every tool on this site does the whole job the first time you open it.
The working is shown, not hidden
Calculators print the formula and every intermediate value. Converters print the exact factor used. If a result looks wrong you can check it by hand instead of guessing what the page did.
