Why Pixellin
Nothing is uploaded
Every tool runs inside your browser with Web Workers and WebAssembly. Your images never touch a server, so there is nothing to leak, store or delete.
Built for batches
Drop up to 200 images at once. Each one shows its before and after size, and you can retry, remove or download them one by one or as a single ZIP.
Honest results
Compression never quietly makes a file bigger, progress shows what is really happening, and limitations are stated plainly on every page.
No account, no catch
No sign-up, no watermarks, no daily limits and no “premium” wall in front of the download button.
Privacy by architecture
Your files stay with you
This tool runs entirely inside your browser using Web Workers and WebAssembly. Your images are never uploaded, never stored on a server and never used to train AI. Close the tab and they’re gone.

Frequently asked questions
Are Pixellin’s image tools really free?
Yes. Every tool is free to use without an account, without watermarks and without daily limits. The site may show clearly labelled ads in the future, never on top of the tools.
Are my images uploaded to a server?
No. Pixellin processes images entirely in your browser using Web Workers, Canvas and WebAssembly. The files stay on your device, and you can even disconnect from the internet after the page and its codecs have loaded.
How many images can I process at once?
Up to 200 files per batch, up to 50 MB and 100 megapixels each. On phones, very large batches depend on available memory, so smaller groups of 20–50 photos are the most reliable.
Which formats are supported?
Pixellin reads JPG, PNG, WebP, AVIF, HEIC/HEIF, GIF, SVG, BMP, TIFF and ICO, and writes JPG, PNG, WebP, AVIF, GIF and ICO. See the formats guide for details on each one.
Does it work on iPhone and Android?
Yes. Pixellin works in current Safari, Chrome, Firefox and Edge on phones, tablets and computers, with nothing to install. On phones you can share results straight to Photos or other apps.
Do I need to install anything?
No. Pixellin is a website. Some codecs, like the HEIC decoder or the AVIF encoder, are downloaded once the first time you use them and then cached by your browser.
