What JPG to WebP does

Convert JPEG images to WebP, the format built for the web. For the same visual quality WebP files are typically a good deal smaller, which is why it has become the default choice for site images — smaller files mean faster pages, and page speed feeds directly into how a site is ranked and how many visitors stay.

The JPEG is decoded in the browser and re-encoded as lossy WebP at quality 90 — close to the top of the scale, chosen so the second lossy pass adds as little as possible. WebP's encoder predicts each block from its neighbours before compressing, which is why it needs fewer bytes than JPEG for the same appearance; the saving is largest on smooth photographic areas and smallest on images that were already heavily compressed.

The output has no EXIF block. If you need the capture date or camera model preserved, note it before converting. WebP supports transparency, but a JPEG source has none, so the output is opaque.

Limitations

  • The image is rebuilt from its pixels, so EXIF metadata (camera, date, GPS location) is not in the output.
  • Lossy WebP re-encodes an already lossy JPEG; at high quality settings the gain is modest and at low settings artefacts compound. Around quality 80 is the usual sweet spot.
  • Some older software (and email clients) still cannot open WebP; keep the JPG if the recipient is unknown.

Questions

Does every browser support WebP?

Every current major browser does. Very old versions do not, so if your audience includes legacy systems, keep a JPEG fallback alongside the WebP.

How much smaller are WebP files?

Commonly around a quarter to a third smaller than a JPEG of comparable quality, though it varies with the image. Photographs with smooth gradients tend to benefit most.

Should I use WebP for print?

No. WebP is designed for screens and web delivery. Printers and print shops expect JPEG, TIFF or PDF, so keep a JPEG copy for anything heading to print.
