PixelKit is a collection of small image utilities that run entirely inside your web browser. No account, no upload, no watermark.
Why browser-based?
Most "free online image tool" sites work the same way: you upload your file, a server processes it, and you download the result. That means a copy of your photo sits on somebody else's machine, subject to their retention policy, their staff and their security.
PixelKit does the work in JavaScript, in the tab you already have open. The image is read from your disk into your browser's memory, processed with the standard Canvas and WebAssembly APIs, and written straight back to your downloads folder. Nothing is transmitted. You can prove this to yourself: load any tool page, turn off your network connection, and the tool still works.
What that means in practice
- Privacy. We cannot see your files, because they never reach us.
- Speed. No upload and download round trip. Large files are usually faster this way.
- No limits. There is no per-file size cap or daily quota to enforce, because we are not paying for the compute — your device is.
- One trade-off. Very large batches are limited by your device's memory, and a phone will give up sooner than a laptop.
How the site is paid for
Hosting a static site is cheap, but not free of time and domain costs. The site carries advertising to cover that. Ads are clearly separated from the tools, never disguised as download buttons, and never placed inside the working area of a tool.
