How Pixitools Works
Every tool on this site follows the same privacy-first principle: your images are processed entirely inside your browser and never leave your device.
Working
Five steps, the same for every tool on the site.
Choose a tool
Pick what you need — convert, resize, compress, crop, rotate, flip or a Base64 utility.
Upload your image
Drop one or more files onto the page. They load straight into your browser's memory.
Adjust settings
Set dimensions, quality, format or crop region. Every control previews what will happen.
Process in your browser
Decoding, transforms and re-encoding run locally via Canvas and WebAssembly — nothing is sent anywhere.
Preview and download
Check each result, then download files individually or as a ZIP. Your originals are never modified.
Built on browser-native processing
No plugin, no app, no round-trip to a server. Your browser already ships everything needed — Pixitools just orchestrates it:
Decode
Your file is read into memory and decoded to raw pixels using the browser's native image decoders — or a WebAssembly codec for AVIF.
Transform
The operation you chose runs on those pixels through the Canvas API, entirely on your device.
Encode
The result is re-encoded in your chosen format and offered as a download. Nothing was uploaded at any point.
What this means for your privacy
Because processing never leaves the page, there is no upload step to secure, no server copy of your images and no account tied to your files. Closing the tab discards everything.
Available tools
Nine tools, one consistent flow. Open any of them to start:
Supported formats
What you can feed in and get out.
All tools work with JPEG/JPG, PNG and WebP. The converter additionally accepts and produces AVIF, BMP and SVG inputs — for example SVG → PNG or BMP → WebP — using a local WebAssembly codec for AVIF and a dedicated BMP encoder. The Base64 utilities also handle GIF. SVG works as an input format; raster-to-vector output is not offered.
Frequently asked questions
No. Pixitools is a website that runs in any modern browser. There is nothing to install and nothing to sign up for.
Browsers can decode, draw and re-encode images locally via the Canvas API. Heavy codecs like AVIF run as WebAssembly modules that your browser executes natively — the same power a server would use, just on your device.
There is no artificial limit: processing capacity depends on your device's memory and CPU. Very large images simply take a little longer.
After the page and (for AVIF) the WebAssembly codec have loaded, all processing happens locally, so it keeps working without further network access.
