Convert a JPG to WebP for a smaller file

For photographs on the web, WebP typically beats JPG on size at the same visual quality — a useful win when page weight matters. Converting your JPGs to WebP is a common step when optimising a site's images.

Set the quality to taste; a WebP at 80% is usually smaller than the equivalent JPG and looks the same. Bear in mind the source JPG has already been compressed once, so this is a re-encode rather than a pristine original.

What this does — and what it doesn't

  • This re-encodes an already-compressed JPG, so it's a second lossy pass. The size win is real, but keep the quality reasonably high to avoid stacking artefacts.
  • Some older software can't open WebP — use JPG or PNG when maximum compatibility matters more than size.

JPG to WebP — frequently asked questions

Will re-encoding a JPG to WebP hurt quality?
It's a second lossy step, so in principle yes, but at a sensible quality setting the loss is invisible while the file gets smaller. Avoid pushing the quality very low, which would compound the JPG's existing compression.
Can I convert several images at once?
Yes. Drop or choose as many files as you like: they are all converted with the same settings, you see each result's size before downloading, and Download all gives you one ZIP. To shrink files without changing their format, the Image Compressor is the better fit.
Are my images uploaded anywhere?
No. The conversion runs entirely in your browser using the canvas API and, for some formats, WebAssembly — the image never leaves your device. Most conversions keep working with the internet switched off once the page has loaded. A few (HEIC, TIFF, AVIF and PNG to SVG) download a helper file from this site the first time you use them; if you are offline at that moment you are told so, not blamed for a broken file. There is no upload endpoint to send anything to.
Is it really free?
Yes — no account, no watermark, no daily limit, and no paid step at download. It's free because there's no server doing the work, so it costs us almost nothing to run.
