WebP to JPG Converter
Drop WebP files here or click to choose. Several files are fine.
Decoded locally with canvas. Nothing is uploaded.
Higher keeps more detail and a larger file. Transparent pixels fill white before encode.
When JPG is the right export
WebP is great on the web, but email clients, some LMS uploads, and older printers still insist on JPEG. JPG is lossy and smaller than PNG for photos. Reach for this page when size and compatibility matter more than lossless pixels. If you need a lossless raster with transparency, use the WebP to PNG converter instead.
Quality slider and expected size
The slider sets the canvas toBlob quality (0.50 to 1.00). Moving it re-encodes every successful file so you can compare KB before you download. Rough expectations for a typical photo-style WebP:
| Quality | What you usually see |
|---|---|
| 0.95 to 1.00 | Near-source detail, largest JPG |
| 0.85 to 0.92 | Good default for forms and email |
| 0.70 to 0.80 | Noticeable savings, mild softness |
| 0.50 to 0.65 | Small files, visible blockiness |
Transparency and animation
JPEG cannot store alpha. Before encoding, this tool fills the canvas with white, then draws the decoded WebP on top. Transparent regions become white in the download. Animated WebP collapses to one still frame. Very large images can exhaust tab memory; shrink the source if the tab stalls.
FAQ
How does this WebP to JPG converter work?
Your browser decodes each WebP with the Image API, draws it on a canvas over a white background, then encodes JPEG at the quality you set. Files stay on your device. ToolPetal never uploads them.
What JPEG quality should I use?
0.92 is a solid default for photos and screenshots. Drop toward 0.75 when you need smaller files and can accept mild compression. Values under 0.5 show obvious artifacts. The list updates when you move the slider so you can compare sizes before downloading.
What happens to transparent WebP pixels?
JPEG has no alpha channel. This tool paints a white background under the image before encoding, so transparent areas become white in the JPG. If you need to keep transparency, use the WebP to PNG converter instead.
Can I convert animated WebP to JPG?
Only as a still. Canvas captures one frame, so the download is a single JPEG. For multi-frame output you need a different workflow outside this page.
