Free, and staying free. No account, no daily limit, no watermark, nothing uploaded. Keeping it up does cost something (the domain, and the AI that reads your notification) and a contribution goes there. Passing the site to someone filling the same form helps just as much, and costs nothing at all.

About JPG to WEBP

WEBP was designed to replace JPG on the web and generally reaches the same visual quality in roughly 30% fewer bytes. For a website that is a direct speed improvement, and page speed feeds into search ranking, which is why site owners do this in bulk.

Good to know

  • Every current browser supports WEBP. Some older desktop software and a few upload forms still do not.
  • The saving is real but not free: it is a second lossy encode, so work from the best JPG you have.
  • Excellent for images on your own site, risky for a file somebody else has to open.

Questions

Is WEBP safe to use on a website now?

Yes. Browser support has been universal for years. Keep a JPG fallback only if you must support genuinely ancient software.

Will I see the quality drop?

Rarely at normal settings. You are re-encoding an already lossy file, so start from the highest-quality JPG available.

Can I email a WEBP?

You can, but the recipient may not be able to open it easily. JPG remains the safer choice for sending to people.

How much smaller is it really?

Around 25 to 35% for typical photographs, though it varies with the content.

Is my file uploaded anywhere?

No. Everything runs inside your browser using your own device. Your file never leaves it, and we never see or store it. You can even disconnect from the internet and the tool still works.

Is it really free?

Yes. No account, no daily limit, no watermark on your files. The site is paid for by ads.
