How to use it

! Output support depends on the browser encoder; WebP is not available everywhere.
! Transparency survives PNG and WebP but not JPG.

Which format should I pick?

PNG for graphics and transparency, JPG for photos, WebP for the smallest web delivery.

Can I batch convert?

Yes, drop several files and download a zip.

Does it resize?

No, dimensions are kept; use the resize tool for that.

Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
