Are my images uploaded to a server?

No. Each converter runs entirely in your browser using the canvas API and, for some formats, WebAssembly. Your image never leaves your device. Most conversions keep working with the internet off once the page has loaded; HEIC, TIFF, AVIF and PNG to SVG download a helper file from this site the first time, and tell you plainly if you are offline when that happens.

Which image format should I convert to?

JPG for photographs, where it's smallest. PNG for logos, screenshots and anything needing transparency or lossless editing. WebP and AVIF for the web, where they're smaller than both. SVG for vector logos that must scale. ICO for favicons and Windows icons.

Yes — no account, no watermark, no daily limit, and no paid step at download. It's free because there's no server doing the work, so it costs us almost nothing to run.

Can I convert many images at once?

Yes. The converter at the top of this page and the PNG, JPG, WebP, AVIF, HEIC, GIF, BMP, TIFF and SVG pages take many files at once, convert them all with the same settings and give you a ZIP. The top converter also works out each file's format by itself, so you can mix PNG, HEIC, WebP, SVG and more in one go. The icon (ICO) and tracing-to-SVG pages take one file at a time.
