Choose the quality, see the size.

Choose the quality

The sizes are measured after the conversion, so the choice is a comparison rather than a guess.

    What this tool does, exactly

    The conversion most upload forms force on you, done without handing the picture to anyone. A JPG has no transparency, so any transparent pixels become the colour you choose, and the quality choices are named for what they are for rather than numbered.

    What it does
    Decodes the WebP with your browser's own codec and writes it out as a JPEG at full resolution and the quality you chose. Two lossy formats in a row means a little more loss; at Balanced it is not visible at normal viewing size.
    Transparency has to become something
    JPEG has no alpha channel, so every transparent pixel needs an actual colour. Most converters use black and say nothing. The colour is yours to choose here, it starts at white, and the share of the picture that was transparent is counted and shown.
    Animated WebP
    Only the first frame is converted, and the result says so rather than handing you a still and hoping you do not notice.
    What is left in the file
    Nothing but the pixels. Metadata the WebP carried is stripped, and the result lists what was there before.

    About this tool

    Which quality should I choose?

    Balanced for anything going in an email, a form or a web page. Best when the picture will be printed or looked at closely. Small when a size limit is the whole problem — though if the limit is a specific number of megabytes, the image compressor on this site is the better tool: it finds the quality that fits under a size you name.

    What happens to the transparent parts?

    They become the background colour you choose, white by default or black. JPEG cannot record transparency, and a converter that appears to keep it has simply picked a colour without telling you. The result names the share of the picture that was transparent.

    Will the JPG be smaller than the WebP?

    Usually not by much, and sometimes it is larger. WebP compresses roughly a quarter to a third tighter than JPEG at the same visible quality, so the same picture as a JPG typically needs more bytes. Both sizes are shown.

    Is my picture uploaded?

    No. Decoding and encoding both happen in this browser tab. Nothing leaves the device.
