JPG to WebP Converter

Convert JPG images to WebP online for free. Batch conversion in your browser, no upload limits and no credits used.

WebP typically stores the same photograph at roughly a quarter to a third less than JPEG for equivalent visual quality, and every current browser reads it. For images you serve on a website, this is usually the single cheapest speed improvement available.

Where the saving comes from

WebP uses a more modern compression method than JPEG, which was standardised in 1992. It predicts blocks from their neighbours more effectively and encodes the difference more compactly, so it needs fewer bytes to reach the same perceived quality โ€” typically 25โ€“35% fewer on photographic content.

  • The saving is largest on photographs and smallest on images that were already heavily compressed.
  • Smaller images improve Largest Contentful Paint, which is a ranking-relevant page speed metric.
  • Browser support is effectively universal now; the compatibility argument for staying on JPEG has expired.

Convert from the best source you have

Converting a JPEG to WebP means decoding lossy data and re-encoding it lossily, so a second round of loss is stacked on the first. It is normally invisible, but it is avoidable: if you still have the original camera file or the export from your editor, produce the WebP from that instead of from the JPEG.

When JPEG is still the answer

Keep JPEG when the file has to leave the web โ€” a print shop, a client's desktop software, a marketplace upload form, or an older device may simply refuse a .webp. The right pattern for most sites is WebP for delivery and a JPEG kept aside for anything that has to travel.

Frequently asked questions

Do all browsers support WebP?
Yes โ€” every current version of Chrome, Safari, Firefox, and Edge reads WebP. Support outside browsers, in desktop software and print workflows, is where gaps remain.
How much smaller will the WebP be?
On photographic content, typically 25โ€“35% smaller than a JPEG of equivalent visual quality. Images that were already compressed hard will save less.
Will converting lose quality?
A little, because you are re-encoding data that a JPEG encoder already compressed. It is normally invisible. Converting from the original export rather than from the JPEG avoids it entirely.
Is it worth converting images that are already optimised?
Less so โ€” the more aggressively a JPEG was already compressed, the less WebP has left to save. The big wins are on large, lightly compressed photographs.
