WebP Converter
Convert any image to modern WebP format for smaller, faster web images.
Convert any JPG, PNG, or other image to WebP, the modern format built for the web. WebP files are typically 25-35% smaller than equivalent JPGs and 50%+ smaller than PNGs, while keeping transparency. Faster pages, lower bandwidth, sharper images at the same byte budget.
Everything runs in your browser. The conversion uses your device's built-in WebP encoder, so your images are never uploaded and no server ever sees them. Drop a file, tune the quality, and download, all offline once the page has loaded.

About WebP Converter
Convert any image to modern WebP for smaller, faster-loading web images — typically 25–35% lighter than JPG or PNG at the same quality. Runs in your browser, no upload.
How to use the WebP Converter
- 1
Drop in your image
Add a JPG, PNG, or other supported file. It loads locally into the page; nothing is sent anywhere.
- 2
Pick a quality level
WebP supports both lossy and lossless. Quality 75-85 is the sweet spot for photos; choose lossless for graphics where every pixel matters.
- 3
Convert
The browser re-encodes the image to WebP on the spot. Larger images take a moment, but there's no upload delay.
- 4
Download and compare
Save the .webp file and check the new size against the original. Re-run at a lower quality if you want it even smaller.
When WebP is genuinely worth it
WebP pays off most on websites. If you serve product photos, blog images, or thumbnails, switching to WebP commonly cuts image payload by a third, which directly improves Largest Contentful Paint and your Core Web Vitals score. On a media-heavy page that can mean shaving hundreds of kilobytes off every visit.
It's less essential for a single image you're emailing or printing, where universal compatibility matters more than a few saved kilobytes. WebP also beats PNG dramatically for transparent graphics: a logo that's 200 KB as PNG often drops below 60 KB as lossless WebP with identical pixels.
Compatibility you can count on
WebP is supported by every current browser, Chrome, Firefox, Safari, Edge, and by Android and iOS. That worry about support is years out of date. The remaining gaps are old software: some legacy desktop image viewers, older Office versions, and email clients may not preview WebP inline.
The practical rule: use WebP freely for anything displayed on the web. For files a recipient will open in arbitrary desktop apps, or upload somewhere with strict format rules, keep a JPG or PNG fallback. Many sites serve WebP with a JPG fallback via the picture element for exactly this reason.
Quick tips
- ✓Quality 80 lossy WebP is the reliable default for web photos; you'll struggle to spot the difference from the original at a much smaller size.
- ✓For logos, icons, and flat-color graphics, use lossless WebP, it beats PNG on size while staying pixel-perfect.
- ✓WebP keeps transparency, so converting a transparent PNG won't add an unexpected white background.
- ✓Don't convert an already-tiny image; the WebP container overhead can make very small files slightly larger.
- ✓If a CMS or marketplace rejects the upload, it likely doesn't accept WebP yet, convert to JPG for those specific platforms.
Frequently asked questions
Is WebP supported everywhere?
All modern browsers support WebP (95%+ of users). For maximum legacy compatibility, keep a JPG/PNG fallback.
Does WebP support transparency?
Yes — WebP supports transparency like PNG, but at a smaller file size.
Lossy or lossless WebP?
Use the quality slider: high quality stays near-lossless, lower quality yields the smallest files for the web.
Is WebP lossy or lossless?
It can be either. Lossy WebP competes with JPG and is best for photos; lossless WebP competes with PNG and is best for graphics and transparency. This tool lets you choose.
Will WebP look worse than my JPG?
At matched quality settings, WebP generally looks the same or better than JPG while being smaller. Quality loss only shows if you push the slider very low.
Can I convert WebP back to JPG or PNG later?
Yes. Use the convert-image tool to go from WebP to JPG or PNG anytime. Note that converting lossy WebP to JPG won't restore detail already discarded.
