About the JPG to WebP
WebP files are typically 25 to 35% smaller than JPGs that look the same, which is why fast websites use them. This converter turns JPG and JPEG photos into WebP in bulk, right in your browser. Choose the quality with a slider, watch each file's new size and download them one by one or as a ZIP. It's handy for blog images, online shops and portfolios, or simply to save space. Your photos never leave your device.

How to use the JPG to WebP
- 1Click Select images or drop JPG photos on the page.
- 2Choose the quality; 80% is a good default.
- 3Wait while the photos convert.
- 4Check the sizes in the list.
- 5Download the WebP files or a ZIP.
Faster pages with the same photos
A typical blog post with ten photos can save several megabytes by switching to WebP. Pages load faster, use less mobile data and score better in speed tests, with no visible change for readers.
Picking a quality
WebP and JPG quality numbers are not the same scale, so compare the result rather than copying the number.
- 90%: for photography portfolios
- 80%: for most websites and shops
- 70%: for thumbnails and previews
- Check one photo at full size before converting hundreds
Keep the originals
WebP from a JPG is a second round of lossy compression. Keep your original JPGs or camera files as the master copies, and treat the WebP files as the versions you publish.
Privacy bonus
Because the converter redraws the photo, camera details like the phone model and GPS location are left out. That makes the WebP safer to post publicly.
How WebP beats JPG
WebP's lossy mode comes from the VP8 video codec. It predicts each block of pixels from its neighbours and stores only the difference, which handles smooth areas like skies and skin more efficiently than JPG's older method. At the same file size, WebP shows fewer blocky artefacts; at the same look, the file is smaller.
Resizing and converting together
Phone photos are often 4000 pixels wide, far more than a web page needs. For the biggest saving, resize photos to about 1600 to 2000 pixels wide first, then convert them to WebP. The combination often turns a 4 MB photo into a 200 KB WebP that still looks sharp on screen.
Where WebP isn't the right choice
Some print shops, older email programs and government upload portals only accept JPG or PNG. Keep the JPG for those. For archiving your photo library, stay with JPG or the original camera format, because every program can open it.
Any device
Works in Chrome, Edge, Firefox and Safari on phones, tablets and computers. If the picture has a see-through background, use PNG to WebP, and when you need the old type back, WebP to JPG converts it.

Frequently asked questions
How much smaller is WebP than JPG?
Google's studies found about 25 to 34% smaller at the same quality. Your results depend on the photo and the quality you pick.
Will converting improve quality?
No. Converting can't add detail the JPG lost. Pick a quality of 80% or more so you don't lose more.
Can everyone open WebP files?
Every modern browser can, as can Windows 10 and 11, macOS and phones. Some older editing programs and print shops don't accept WebP yet.
Is EXIF data kept?
No. Camera details and GPS location are not copied, which is good for privacy when you publish photos online.
Can I convert on my phone?
Yes, pick photos from your gallery and download the WebP files.
Why did some files come out as JPG?
Older Safari versions can't save WebP, so the tool saves JPG instead and shows a note.
Does it change the photo's size in pixels?
No. The WebP has the same width and height. To make photos smaller in pixels as well, run them through the Image Resizer.
Can I convert many photos at once?
Yes. Add as many as you like and download them together as a ZIP.
Which is better for my website, JPG or WebP?
WebP, if your website platform accepts it, because pages load faster. Keep JPG only where a service or old browser requires it.
