Why websites ask for WebP
Drop your JPG photos here, choose how light the files should be, and press Convert to WEBP: that is all it takes to turn JPEG to WebP. Your browser does the work, so the photos never leave your device, and each WebP keeps the name of its photo, with .webp in place of .jpg.
Websites want WebP because it is lighter. A smaller picture is less to download, so the page appears sooner, most of all on a slow connection. In our tests, a 3.9 MB camera photo came out at 1.3 MB with the default setting, at the same width and height.
The trade-off is reach. Current Chrome, Edge and Firefox show WebP, but some older programs and upload forms still turn it away. Keep your JPGs as the originals, and when you need one back, convert WebP to JPG.

Photographs, compressed. Small files, no transparency, slight fuzz.
The web’s efficient format. Smaller than JPEG, refused by older software.
WebP compresses the picture, so fine detail is lost. It looks right at normal size.
Smaller, Balanced or Best
Image quality has three settings. Each one makes a lossy WebP, which drops some fine detail to save space; they differ in how much. Our three test photos came out at these sizes in Chrome:
| Photo | JPG | Smaller | Balanced (the default) | Best |
|---|---|---|---|---|
| From a camera, 4032 × 2688 | 3.9 MB | 788 KB | 1.3 MB | 3.7 MB |
| Aerial view, 4096 × 2160 | 3.4 MB | 326 KB | 477 KB | 1.1 MB |
| Saved for the web, 1600 × 843 | 307 KB | 77 KB | 118 KB | 297 KB |
Balanced suits most photos for a website: it cut our files by 62 to 86%, and at normal size we could not tell them from the JPGs. Smaller saves more again, but zoomed in it softens fine texture such as sand or gravel. Best keeps the most detail, yet a JPG that was already compressed barely shrinks with it: our web photo went from 307 KB to 297 KB. Firefox gave sizes within 1% of these.
Converting a whole folder
To batch convert JPG to WebP, open the folder in the file picker and select every photo, or drag them all onto the page. One run takes up to 100 files; add more and the page keeps the first 100 and tells you. The photos are converted in turn on your device, all at the Image quality you picked.
Every WebP has a Download button of its own. With two or more, Download all (ZIP) saves the whole set as whatafile-converted.zip. There is no daily limit and no account, so this free JPG to WebP converter is ready for the next folder straight away.
What is left out of the WebP
- The hidden details (EXIF): camera model, date taken and GPS location are all dropped, so a photo you publish does not say where it was taken.
- The sideways flag: a photo stored on its side comes out the right way up, because the turn is applied to the pixels.
- A wide colour profile: the WebP does not carry it, so a photo in Adobe RGB, which some cameras use, has its colours changed to ordinary sRGB on the way and keeps its look as closely as sRGB allows. An ordinary sRGB photo is not changed.
The width and height in pixels stay as they are. A camera photo 4032 pixels wide is far wider than most pages need, so to make it lighter still, resize the photo to the width you need, then convert it.
Not every picture on a site is a photo. A screenshot or logo with a see-through background has no place in a JPG: convert PNG to WebP and the transparency stays. A moving GIF keeps every frame when you convert GIF to WebP, and an icon drawn as vector shapes can become pixels if you convert SVG to WebP. For which format suits which picture, read JPEG vs PNG.
Questions people ask
How do I change JPG photos to WebP?
Select or drop the JPGs on this page, up to 100 at once. Pick Smaller, Balanced or Best under Image quality and press Convert to WEBP. Save each WebP with its Download button, or every one together with Download all (ZIP).
Does a JPG lose quality when it becomes a WebP?
A little. This page always makes lossy WebP, so JPG to WebP without losing quality is not possible here. At Balanced our test photos looked the same as the JPGs at normal size, and Best keeps the most detail. Marks already in the JPG stay, because converting cannot add detail back.
How much space does WebP save over JPG?
It depends on how the JPG was saved. A camera stores photos at high quality, which leaves plenty to trim: at Balanced our 3.9 MB camera photo became 1.3 MB. A JPG already made for the web has less to give: our 307 KB one became 118 KB, and at Best it hardly shrank, to 297 KB.
Will every app open my WebP files?
No. Current Chrome, Edge and Firefox show WebP, but some older programs and upload forms refuse it. Keep the JPGs, or turn a WebP back into a JPG on the WebP to JPG page when you need one.
Does converting to WebP remove the location from a photo?
Yes. The WebP carries none of the hidden details (EXIF) from the JPG: no GPS location, camera model or date taken. The location in our test photo was gone from every WebP we made.
Is converting JPG to WebP free?
Yes, and there is no daily limit. The conversion runs in your browser, so it costs us nothing to run.
What happens to my files?
Nothing leaves your device. The JPG is read and the WebP is made inside your browser, so there is nothing on our servers to delete.
Will the WebP look exactly like the JPG?
This pair grades as “Very good”. We show the exact route and that grade before you convert, so there are no surprises about what survives the trip.
Do I need to install anything?
No. Pick or drop a file here, it is converted in your browser, and you save the result.
How large can my file be?
As large as your browser can handle: pictures up to about 90 megapixels on a typical computer, less on a phone.
Can I convert several files at once?
Yes. Add up to 100 files at a time and they convert one after another on your device.
