How it works

Smaller files, honest about the trade

  1. 1

    Pick an image

    Up to 25 MB, any format your browser can decode. It is read locally — no upload, no queue, no account.

  2. 2

    Choose a format

    Only the formats your browser can actually encode are offered. Nothing here silently hands you a PNG with the wrong file extension on it.

  3. 3

    Set the quality

    For JPEG and WebP, the dial trades file size against detail. Around 80% usually keeps the picture and drops most of the bytes.

  4. 4

    Compare, then download

    Original size, converted size and the percentage saved are all shown before you commit — so you can tell when a conversion is not worth it.
