Frequently asked questions

No. The image tools run entirely in your browser using built-in browser features and code served with the page. Your files are never sent to WebAssetKit. You can check this in your browser’s developer tools (Network tab) or by disconnecting from the internet after the page loads.

Yes. There is no sign-up, watermark or daily limit. The site may show advertising to cover hosting; see the Privacy Policy for how that is handled.

You can open JPG, PNG, WebP, GIF, BMP and SVG, plus AVIF and HEIC when your browser can decode them. You can save as JPG, PNG or WebP (where your browser supports encoding it). Each tool page lists its own limits.

There is no server limit because nothing is uploaded, but your device’s memory is the limit. The tools refuse files over 25 MB (5 MB for Base64) or above 100 megapixels, and mobile browsers may fail earlier on very large images.

Browsers can read those formats but cannot create them from a web page. Only JPG, PNG and WebP can be created reliably, and WebP creation is not available in every browser (Safari has historically lacked it).

PNG is a lossless format and photographs contain a lot of detail. This site reduces colours to shrink PNGs, which works very well for graphics and screenshots but less so for photos. Converting photos to JPG or WebP usually saves far more.

After the page has loaded, the tools do not need the internet. Reload will need a connection, because this site is not an installable offline app.

Current versions of Chrome, Edge, Firefox and Safari. Old browsers that lack basic features such as the Canvas or File APIs will show a message instead of the tool.
