About JPG to WebP

Where JPG files come from

Photos from cameras and phones are JPG, and big JPGs are a common reason web pages load slowly. Page speed tools often suggest serving images in a next-generation format; WebP is the one every current browser shows.

What changes

  • WebP compresses the photo again, with some loss. At High quality it looks the same.
  • The picture is turned upright for good.
  • The date, camera, and location stored in the JPG are not carried over.
  • The file is smaller, by how much depending on the quality.

Measured

Our 12-megapixel sample photo as JPG and a 1024 by 1024 pixel logo as JPG, converted in Chrome on a laptop. Phone timings are still to be measured.

Photo, JPG to WebP, High quality2.1 MB to 1.3 MB
Photo, Smaller file quality265 KB
Logo, High quality48 KB to 16 KB
Time for the photo in Chrome (laptop)0.9 seconds

In your browser

Chrome, Edge, and Firefox write WebP themselves, so nothing extra is downloaded. Safari's canvas can't write WebP, so Safari downloads an encoder of about 120 KB (libwebp) for the first conversion and then reuses it from its cache.

Limits

  • WebP can't be larger than 16383 pixels on a side.
  • Some older programs, email apps, and print shops can't open WebP. Keep the JPG for those.
  • Very large images may be reduced to about 16 megapixels on iPhones. The result says so.

Other options

  • JPG to AVIF: smaller still, though slower to make and not read by older browsers.
  • Compress image: keep the JPG format and make it smaller, or reach a target size.
  • WebP to JPG: turn a WebP back into a JPG.

Questions

How much smaller is WebP than JPG?

It depends on the quality you pick. Our 2.1 MB sample photo became 1.3 MB at High and 265 KB at Smaller file. Google measured WebP at 25 to 34 percent smaller than JPG at the same look.

Are my images uploaded?

No. Your files are processed on your device. We never upload them.

Does converting JPG to WebP lose quality?

A little, because the JPG is compressed a second time. At High or Best the difference is hard to see. Convert from the original JPG rather than from an already-converted copy.

Is the location removed?

Yes. The WebP carries no photo details, so the location, date, and camera are left out. That makes it safe to publish.

Will WebP work on my website?

Yes. Every current browser shows WebP, and WordPress, Shopify, Squarespace, and most other site builders accept it.

Can I convert many images at once?

Yes. Choose or drop as many as you like and download them all as one zip.
