JPG to WebP Converter
Convert a JPG image to the modern WebP format — smaller files at the same visual quality.
How to Convert a JPG to WebP
- Click the upload area or drag a JPG/JPEG file onto it.
- Wait a moment for the tool to confirm your browser can export WebP — if not, a notice appears at the top explaining why.
- Adjust the "WebP Quality" slider (30–100%, default 85%) to balance size and quality.
- Check the JPG Size vs. WebP Size stats, then click "Download WebP".
Frequently Asked Questions
Why does the page say my browser doesn't support exporting WebP?
Before you upload anything, the tool tests whether your browser's canvas can actually encode a WebP image. Some older browser versions can decode WebP but can't produce it, so on those the upload area is disabled and a notice explains you'll need a recent version of Chrome, Edge, or Firefox.
How much smaller will my WebP file be?
It depends on the image, but WebP's lossy compression is generally more efficient than JPEG's at the same visual quality - the exact savings are shown in the JPG Size / WebP Size stats after each conversion, so you can compare directly.
What does the Quality slider change?
It's passed straight to the browser's WebP encoder as a compression quality value between 30% and 100%. Lower values shrink the file further but introduce more visible compression artifacts; the preview updates automatically about 120ms after you stop dragging.
Does the converted WebP keep my JPG's EXIF data?
No. The tool draws your JPG onto a canvas and re-encodes it as WebP, which produces fresh image data without the original file's metadata.
Is this conversion done on a server?
No - everything runs in your browser using the Canvas API's toBlob() method. Your JPG is never uploaded anywhere.
