Frequently asked questions
- Is the result exactly 20 KB?
- We tune the encoder until the file lands just under 20 KB, keeping the best quality possible at that size.
- Are my photos uploaded to a server?
- No. Processing happens entirely in your browser, so your image never leaves your device.
- Which formats can I use?
- JPG, PNG, WebP, AVIF, GIF, TIFF and HEIC. The result is saved in a light format that upload forms accept.
- Will quality drop a lot?
- The lower the target, the more visible the compression. If 20 KB looks too soft, try a slightly larger target from the list below.
