Why switch from JPEG to WebP?
WebP uses a significantly more efficient compression algorithm than JPEG. At the same perceived quality level, WebP files are typically 25-34% smaller. That translates directly to faster page loads, lower hosting bandwidth bills, and better Core Web Vitals scores on Google.
For image-heavy websites, product catalogs, and photography portfolios, the cumulative savings are substantial. A site that serves 100 images per page view might save 20-30 MB of data transfer per user session just by switching to WebP.
The browser support picture for WebP is now excellent. Chrome, Edge, Firefox, and Safari 14+ all support it, covering well over 95% of web users. If you have been holding off on adopting WebP due to compatibility concerns, the window for that concern has largely closed.
For websites, pair WebP images with a picture element and a JPEG fallback to cover the rare legacy browsers that do not support WebP yet.
Convert in three simple steps
Truly secure, no account needed. The conversion is instant and completely private.
Drop your JPEG
Drag the file onto the drop zone or click to browse. You will see a preview and the original file size immediately.
Adjust quality
Use the quality slider to set compression. At 80-85% quality, the WebP output is visually indistinguishable from the original JPEG but significantly smaller.
Download WebP
Click Download to save the WebP file directly to your device. Ready to use on your website right away.
Tips for JPEG to WebP conversion
Keep original JPEGs
Store the source JPEG files. They are your archival copies. WebP is great for delivery but JPEG is more universally editable.
Quality 80-85 is the sweet spot
At this range the WebP is visually identical to the JPEG to most viewers, but noticeably smaller in file size.
Use WebP for web, JPEG for email
WebP is ideal for websites. JPEG remains the safer bet for email clients, which have inconsistent WebP support.
Check with a picture fallback
When deploying on a website, use the HTML picture element with a JPEG source as fallback for older browsers.
Test on mobile too
Mobile users benefit most from WebP savings. Smaller files load faster on cellular connections where bandwidth is limited.
Frequently asked questions
Will the WebP look worse than the original JPEG?
At 80% quality and above, the WebP output is visually indistinguishable from the original JPEG. The file size savings come from a more efficient algorithm, not from removing visible detail.
Can I adjust the output quality?
Yes. Use the quality slider that appears after selecting a file to control the compression level anywhere from 1 to 100.
Do all browsers support WebP?
All modern browsers support WebP. Chrome, Firefox, Edge, and Safari 14+ all handle it natively. For legacy compatibility, provide a JPEG fallback using the HTML picture element.
Is my photo private and secure?
Your images are processed securely and stay private. They are never shared or stored anywhere.
