Will WebP work everywhere?

In every current browser, yes. Some older desktop software still can't open WebP — keep the originals for those.

What quality should I pick?

Around 80 is a common starting point for photos. Compare the result at the size it'll actually be shown.

Are my photos uploaded?

No. They are decoded and encoded by your own browser.

Convert JPG to WebP

Turn JPG or PNG images into smaller WebP files in your browser, in batches, with a quality control. Nothing uploaded.

WebP is the format to use when page weight matters: at a similar visual quality it is usually noticeably smaller than JPEG, and every current browser displays it. Drop one image or a whole folder's worth and convert them in one go.

A quality setting controls the trade-off between size and detail, and you can resize at the same time — usually the bigger saving, since a phone photo is several times larger than any web layout needs.

PNGs work too, and unlike a JPEG conversion, WebP keeps their transparency, so logos and cut-outs stay cut out.

Worth knowing. Re-encoding through the browser drops the photo's metadata — EXIF camera details and GPS location don't carry over into the WebP. That's usually what you want for images going on a website; if you only want to remove metadata without re-compressing, use the lossless EXIF remover instead.
