Free JPG to WebP converter
Create WebP copies ready for modern websites without changing dimensions. Test quality and compare every result with its original JPG.
Why convert JPG to WebP?
WebP is designed to deliver compact images on modern websites and apps. Converting a JPG library to WebP can reduce the amount of data visitors download without changing image width or height.
A JPG is already lossy, so conversion applies a new lossy encode to the current image. Whenever you change quality, Cutflow starts again from the original JPG instead of compressing a previous result.
JPG or WebP for the web
Both work well for photographs, but they serve different delivery needs.
| Source JPG | Output WebP | |
|---|---|---|
| Compression | Lossy | Adjustable lossy compression |
| Compatibility | Very broad, including older tools | Broad in modern browsers and tools |
| Transparency | No | Supported, but absent from a JPG source |
| Best use | Universal sharing | Web delivery and performance |
Choose the right WebP quality
The 90% setting favors fidelity. A value near 80% often works for website photos, but textures, hair, grain, and gradients should always be inspected.
Change quality after the first run to rebuild the entire batch from the original JPG files. The before and after inspector and the size change percentage let you judge the actual result instead of relying on an average claim.
How to convert JPG to WebP
- Drop your JPG files. Add up to 50 images that stay on your device.
- Set the quality. Start at 90%, then compare detail and file size savings.
- Download the WebP files. Save one result or get the complete batch as a ZIP.
FAQ
Will WebP always be smaller than JPG?
No. The result depends on image content, selected quality, and how the source JPG was encoded. Cutflow shows the exact change for every file.
Does conversion add transparency?
No. WebP can store transparency, but a JPG source has no alpha information to restore.
What quality should I use for a website image?
90% is a cautious starting point. Then try 80% and compare detail and size in the magnified preview.
Should I delete the original JPG files?
No. Keep JPG files as master or compatibility copies and use WebP as a delivery format.
