Since every tool on this site runs entirely in your browser, there is no account system and no server logs of your files to look up -- if something isn't working, it helps to mention your browser and roughly what image/file you were converting.

A ZIP with favicon-16/32/48/192/512.png, apple-touch-icon.png, and a real multi-size favicon.ico. Best with a square, simple source image.
Center-cropped and scaled to the exact target size.
Runs entirely on-device via a bundled WebAssembly OCR engine (English) — nothing is uploaded. First use downloads ~7 MB of engine/language data (cached by your browser after that); English only for now.
Runs entirely on-device via a bundled WebAssembly segmentation model — nothing is uploaded. Works best on a single clear subject; first use downloads ~18 MB (cached by your browser after that).
3× AI upscale, entirely on-device — nothing is uploaded. Large images are downscaled to 1024px on the long edge first, to keep processing time reasonable. First use downloads ~200 KB more (the runtime is shared with Background removal, if already loaded).
Paint over a watermark, logo, date stamp, or other unwanted mark, then remove it — filled in using the surrounding pixels, entirely on-device. Works best on simple backgrounds (sky, walls, solid colors); a mark over a busy/textured area will look smoothed rather than perfectly reconstructed.
