Why site owners convert to WebP

This is the one converter on this site aimed squarely at people who run websites. Images dominate page weight, page weight dominates load time, and load time affects both your search ranking and how many visitors stay. WebP compresses the same photo to roughly three-quarters of the JPEG bytes at equal visual quality — a free win you apply once per image, forever.

Drop your JPGs above (twenty per batch), pick a quality, and download a ZIP of WebP files ready for your /images folder. Conversion runs in your browser using its native WebP encoder — the same code that decodes WebP on every page you visit, run in reverse.

Practical quality settings

  • 90%: hero images and photography portfolios — visually identical to the source.
  • 80%: the default for content images: blog photos, product shots, gallery items.
  • 70%: thumbnails, avatars, dense listing grids — WebP holds up noticeably better than JPG this low.

Migration notes

Browser support stopped being a concern years ago — everything current renders WebP natively. Two genuine caveats remain. First, the files are for the web: if a user will download an image to re-upload elsewhere (forms, marketplaces, documents), serve that one as JPG, or they'll hit the compatibility wall our WebP to JPG converter exists to fix. Second, convert from your best originals rather than already-minified JPGs — every lossy format re-encode stacks, and starting clean keeps the 80% setting looking like 90%.

Frequently asked questions

How much smaller is WebP than JPG?
At equal visual quality, typically 20–30% smaller for photos. Across a whole site's image library, that's a meaningful cut in page weight and bandwidth bills.
Do all browsers support WebP now?
Yes — every current browser, and every browser version released since roughly 2020. The old advice about needing JPEG fallbacks is obsolete unless you must support very old corporate environments.
When is JPG still the better choice?
When the file leaves the browser ecosystem: upload portals, print shops, email to unknown recipients, embedding in Office documents. WebP is for the web; JPG is for everything else.
What quality setting should I use for WebP?
80–90% covers most website images. WebP degrades more gracefully than JPG at lower settings, so for thumbnails you can push to 70% before anything looks off.
Does the conversion happen on my machine?
Yes — your browser's own WebP encoder does the work. Nothing is uploaded, and a 20-image batch converts in a few seconds with a ZIP download at the end.
