Why websites use WebP instead of JPG
Photos are usually the heaviest part of a web page. WebP, released by Google in 2010, uses more modern compression than JPG and typically produces smaller files at the same visual quality. Smaller images mean faster pages, which visitors notice and which can help your Core Web Vitals scores.
Every current major browser supports WebP, so for images on a website there's rarely a reason not to use it. For printing, email attachments or sending photos to people, JPG is still the safer choice.
| JPG | WebP | |
|---|---|---|
| Released | 1992 | 2010 |
| Compression | Lossy | Lossy or lossless |
| File size at similar quality | Larger | Usually smaller |
| Transparency | No | Yes |
| Opens in browsers | All | All current major browsers |
| Opens in other apps | Everywhere | Most modern apps; some older ones can't |
| Best for | Sharing, printing, cameras | Photos on websites |
How much smaller will my photos get?
It depends on the photo and the quality you choose, so rather than guess, look at the results: after converting, each row shows the original size next to the new size.
A few patterns hold. Photos that were saved at a very high JPG quality tend to shrink a lot. Photos that were already heavily compressed shrink less, and converting them at Maximum can even make them larger. If a file grows, try High or Medium.
Remember that both formats are lossy. Each conversion throws away a little detail, so always convert from the best original you have rather than from a copy that's already been compressed several times.
Using WebP photos in WordPress
- WordPress has supported WebP uploads in the media library since version 5.8. Convert your photos here, then upload the .webp files as usual.
- Convert before you upload rather than after: you'll use less storage and won't need an image-optimization plugin just for format conversion.
- Check your theme and page builder display the images correctly before replacing the originals across your site.
- Graphics, logos and screenshots with transparency are better handled by our PNG to WebP converter with a lossless option.
Good to know
- By default, EXIF metadata such as camera settings, date taken and GPS location isn't copied to the WebP. For public web images that's usually what you want; set Metadata to Keep if you need it.
- Files ending in .jfif are ordinary JPGs and convert the same way. If you just want them as normal JPGs, rename .jfif files to .jpg losslessly.
- Need to go the other way for an app that won't open WebP? Turn WebP images back into JPGs.
- There's no limit on the number of files. Very large batches depend on your device's memory.
Frequently asked questions
Can I convert JPG to WebP in bulk?
Yes. Select or drop as many photos as you like, click Convert once, and download them together with Download all (.zip).
Are my photos uploaded to your server?
No. Each photo is converted on your device, in your browser, and never uploaded. The page loads its code, ads and cookieless analytics like any site, but your photos don't go with them. See how it works.
Is JPEG to WebP the same thing?
Yes. JPEG and JPG are the same format with different file extensions. This tool accepts .jpg, .jpeg and .jfif files.
Which quality should I use for WordPress?
High (the default) is a good starting point for most blogs and shops. Use Medium for large hero images where page speed matters more than fine detail.
Will converting to WebP reduce image quality?
Slightly, as with any lossy re-encode. At High it's very hard to see. Convert from your original photos, not from already-compressed copies, to keep the best quality.
Why is my WebP file bigger than the JPG?
This can happen if the JPG was already heavily compressed and you chose Maximum. Convert again at High or Medium and compare the sizes shown in the file list.
Can people open WebP images outside a browser?
Most modern apps on Windows, macOS, iOS and Android can. Some older editors and online forms still can't, so keep your JPG originals for sharing.
Does the WebP keep my photo's EXIF data?
Not by default. Metadata is set to Remove, so camera settings, date taken and GPS location are left out, which is usually what you want for public web images. Choose Keep to copy the EXIF and XMP data into the WebP.
