Upload one or many JPG / JPEG photos.
Set the quality while watching the real WebP size and a before/after preview. Resize if you want.
Download each WebP or all of them as a ZIP. Nothing leaves your device.
A JPG to WebP converter that shows you the result first
Real size while you choose
Moving the quality slider encodes your own photo in the background, so you see the exact WebP size and savings, plus an estimate for the whole batch, before you convert.
Before/after comparison
Drag the divider over the photo to compare the JPG and the WebP side by side, and switch to 100% zoom to check fine details at the centre of the image.
Batch, resize and ZIP
Convert dozens of photos in one go, optionally limit the width or height (the aspect ratio is kept and nothing is enlarged), and download everything as a single ZIP.
Private by design
Photos are converted in your browser, never uploaded. EXIF data is removed by default; you can keep camera info and still strip the GPS location.
Why convert JPG to WEBP?
WebP is an image format made for the web. For the same visual quality a WebP photo is usually noticeably smaller than a JPG, so pages load faster, use less mobile data and score better in speed tests such as Core Web Vitals. Every current browser can display WebP, and most website builders, CMS platforms and image CDNs accept it.
Tips for the best result
- Pick a size for websites: a phone photo is often around 4000 px wide, far more than most page layouts show. Choosing a longest side such as 1920 px, or a custom maximum width and height, usually saves more than lowering the quality. The aspect ratio is kept and small images are never enlarged.
- Judge detail at full size: compression artefacts rarely show in a small preview, so look at text, skin and smooth skies in the 100% view before you settle on a value.
- Keep your originals: lossy WebP is a delivery format. Store the original JPG files and convert again if you later need a different size or quality.
- Upright photos: the EXIF orientation is applied, so portrait photos from phones never end up sideways.
- Honest lossless mode: the file is checked after encoding, and you are told whether it is truly lossless or maximum-quality lossy.
Privacy and limits
Everything happens in your browser. Your photos are not uploaded, there is no account and no watermark, and the number of files is limited only by your device memory. Metadata is removed by default; you can keep camera details while still removing the GPS location. Wide-gamut photos, such as Display P3 photos from recent phones, are saved in standard sRGB colours. WebP stores at most 16383 pixels per side, so larger panoramas are scaled down to fit. If a file cannot be read, it is skipped and listed at the end while the rest of the batch is still converted.

Frequently asked questions
How much smaller is WebP than JPG?
For photos, WebP at a similar visual quality is often 25-34% smaller than JPG, and much more if the JPG was saved at very high quality or you also resize it. The options window measures the real result on your own photo, so you do not have to guess. A JPG that is already heavily compressed may not get smaller; the page tells you when that happens.
What quality should I use to convert JPG to WebP?
Balanced (80) is a good default for websites: the files are small and the photo looks the same at normal size. Use High (90) for photography portfolios or images that will be zoomed, and Smaller (60) for thumbnails. Drag the before/after divider and use the 100% view to judge for yourself.
Can I convert JPG to WebP without losing quality?
In browsers that support it (Chrome and Edge do), the lossless option stores every pixel of the decoded JPG exactly. It cannot bring back detail the JPG already lost, and the WebP is usually larger than the JPG, so it is rarely the best choice for photos. Some browsers only offer maximum-quality lossy WebP; we read the file that was produced and tell you which kind you got.
Will my photos be rotated correctly?
Yes. Phones often save photos sideways with an EXIF orientation tag. The converter turns every photo upright first, so the WebP looks right in every app, even ones that ignore EXIF.
Does the WebP keep EXIF data and GPS location?
By default all metadata is removed, which makes files smaller and protects your privacy. Turn on "Keep photo info (EXIF)" to copy camera, lens and date into the WebP. GPS location is removed unless you turn that option off too.
Why does my browser say it cannot create WebP?
The conversion uses your browser's built-in WebP encoder. Chrome, Edge and Firefox have one. Safari can display WebP but cannot create it, and on iPhone and iPad every browser uses Safari's engine. Use a computer or an Android device with Chrome, Edge or Firefox.
