FAQ

Is my image uploaded to a server?
No. The conversion happens entirely in your browser using WebAssembly image codecs — your file is never sent anywhere.
Which formats can I convert from and to?
You can start with a JPG, PNG, WebP, GIF, or BMP image, and convert it to JPG, PNG, or WebP.
Will converting to JPG or WebP reduce quality?
JPG and WebP are lossy formats, so some quality is traded for smaller file size. Use the quality slider to control that trade-off — higher values keep more detail.
