Image to WebP
Convert any image to WebP with configurable quality for the modern web.
How to use this tool
- Drop an image.
- Set quality (0-100).
- Choose lossless for graphics if preferred.
- Convert and download.
How it works
canvas.toBlob('image/webp') encodes your redrawn image using your quality setting; lossless mode keeps pixel-perfect output.
Tips
- Quality 80 is often indistinguishable from the original.
- Prefer lossless for logos and UI screenshots with flat colors.
Limitations
Animated images convert as a single frame.
Frequently asked questions
Why WebP?
WebP is typically 25-35% smaller than JPG at equal visual quality and supports transparency — a PageSpeed win.
Which browsers support it?
All modern browsers render WebP; legacy support is no longer a concern for most sites.
Can I keep transparency?
Yes — WebP preserves alpha channels, so PNG graphics convert losslessly-ish without white boxes.
