Will the photo look worse than the JPG?

Not in a way you are likely to see. The tool compares every version it makes against your original and only returns one that still matches it closely. Because it is a second lossy save there is a theoretical loss, but it is far smaller than the difference between one photograph and another.

How much smaller are WebP files really?

Enough to matter, and it varies far too much by image for a single number to be honest. Detailed photographs benefit most; something already heavily compressed benefits least. Your result row shows the exact before and after for your file rather than an average from somebody else's test set.

Should I keep the original JPGs?

Yes, if you have room. Converting is one-way in practice: going back to JPG afterwards means a third lossy save. Keep the originals as your master copies and treat the WebP files as what you publish.

Will WebP work in email?

Not reliably. Email clients are far behind browsers, and some will show a broken image. For email, stay with JPG. For anything on a website, WebP is well supported and has been for years.

Are my files uploaded anywhere?

No. The conversion runs inside your browser, so your images are never sent to us or to anyone else. You can check by disconnecting from the internet once the page has loaded: the tool keeps working.

Can I convert several JPG files at once?

Yes. Add as many as you like, or drop a whole folder in. Each file is handled on its own and gets its own WebP to download, so a file that cannot be read does not stop the others.

Does converting remove the photo's location data?

Usually, yes. Writing a new file drops the hidden metadata a camera or phone attaches, including GPS coordinates. That is often useful before sharing a photo publicly, but do not lean on it as a privacy tool. Check the file yourself if it matters.

JPG to WebP Converter: Free, No Upload

How it works

Three steps to a WebP

1
Add your JPG files
Drag them in, paste from your clipboard, or browse your files. A whole folder at once is fine.
2
Check the settings
Quality is matched to your original automatically. Set it by hand instead if you have been given a number to hit.
3
Download
Save your WebP files. Nothing was sent anywhere, so there is nothing to delete afterwards.

Why this one

Why convert JPG to WebP here

A newer encoder, doing the same job better

JPEG's design is from 1992 and it has aged well, but WebP has better tools: smarter prediction, more modern compression, and no legacy baggage to preserve. On the same photograph at the same visible quality it usually needs meaningfully fewer bytes. Nothing about the picture changes, only how efficiently it is stored.

02
It is a second lossy save
Your JPG already had detail thrown away once. Converting to WebP throws a little more away, because both formats are lossy. It is a small effect and this tool keeps it small by measuring each result against what you gave it, but converting the same file back and forth repeatedly is a bad idea in any format.
03
No limits, no queue
Convert as many JPG files as you like, at any size your browser can handle. There is no server to wait for and nothing for us to ration.
04
A whole folder at once
Drop in as many JPG files as you like. Each one is converted separately and gets its own result, so one awkward file cannot spoil the rest of the batch.
05
It shows you the real numbers
Every file reports what it weighed before and after, and which way it moved. Where another format would have come out meaningfully smaller than WebP, that is offered next to the file instead of being quietly withheld.

Who it's for

When you'd use it

Someone with a slow product page
A shop page carrying twenty photographs is mostly image bytes. Converting them is usually the biggest speed win available, and nothing about the layout has to change.
Someone with a folder of them
A batch that all needs to be WebP before it goes anywhere, dropped in together rather than converted one at a time.
Someone on a work laptop
Software installs are blocked and the files are not theirs to upload to a stranger's server. A browser tab is the only tool available, and it is enough.
