Why convert JPG to WEBP?

WebP is Google's image format for the web. Every current browser shows it, and tools like PageSpeed Insights suggest serving images in formats such as WebP to make pages load faster.

The catch is that a JPG is already compressed. Converting re-encodes the photo, and how much you save depends on how hard the JPG was squeezed in the first place. A high-quality photo straight from a camera or phone usually shrinks a lot. A JPG that was already saved for the web shrinks only a little.

So the best files to convert are large, high-quality JPGs. For logos, screenshots and graphics, start from the PNG if you have it: PNG to WebP keeps sharp edges better than re-compressing a JPG.

Common reasons to convert JPG to WebP:

  • ›Making a website's photos lighter so pages load faster
  • ›Following a PageSpeed or Lighthouse suggestion to use modern image formats
  • ›Uploading to a site builder or CMS that prefers WebP
  • ›Saving space on a large set of high-quality photos

Quality & file size: JPG to WEBP

The WebP is lossy, at quality 85. It looks the same as the JPG at normal viewing sizes, but it's a second round of compression, so it can never be sharper than the JPG.

How much smaller it gets depends on the JPG. In our tests, a high-quality 1920×1280 photo (1.21 MB, saved at JPG quality 95) became a 748 KB WebP — 38% smaller. The same photo saved as a typical 769 KB web JPG became a 750 KB WebP, only 2% smaller, because that JPG was already compressed hard. Each took about 2 seconds.

WebP can hold transparency, but a JPG has none, so the WebP is a plain image without an alpha channel.

Photo details such as the camera model, date and GPS location (EXIF data) are not copied into the WebP.

On the free tier the WebP gets a repeating formatdrop.com watermark, which also makes it a little bigger; Pro output has none.

Frequently asked questions

How much smaller is WebP than JPG?
It depends on the JPG. A high-quality photo can shrink by a third or more — our quality-95 test photo got 38% smaller. A JPG already saved for the web may shrink only a few percent, as ours did (2%).
Does converting JPG to WebP lose quality?
A little, in theory: the photo is compressed a second time. At quality 85 the difference isn't visible at normal sizes, but the WebP can't be better than the JPG you started with.
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox and Safari all show WebP images, on computers and phones. Some older desktop apps and email programs still don't open .webp files.
Should I convert JPG or PNG to WebP?
Use the best original you have. For photos, a high-quality JPG is fine. For graphics, text and logos, convert from the PNG, because re-compressing a JPG keeps its blurry edges.
Will the WebP keep my photo's EXIF data?
No. Camera details, the date and GPS location are not copied. That's often useful for web images, since it keeps location data off your site.
How do I convert many JPGs to WebP at once?
Drop several files together. The free tier converts 2 files a day; Pro converts any number at once, with files up to 500 MB each.
