This tool converts GIF images into modern, compact WebP files in your browser, with an adjustable quality slider. WebP typically beats GIF on file size at the same visual quality and keeps transparency, so images look the same but download faster — ideal for web pages, app assets, and anything where bandwidth matters.
Why bother converting GIF to WebP?
GIF was designed in 1987 for 256-colour images over slow connections. WebP, developed by Google and now supported across all major browsers, uses far more sophisticated compression that achieves:
- Typically 25–70% smaller files at equivalent visual quality
- True alpha transparency (GIF supports only 1-bit on/off transparency, not smooth edges)
- Support for modern image colour depths
For a static GIF that was once used because it supported transparency, WebP is almost always a better choice. The main reason to keep a GIF today is if you need animation — this tool handles only the first frame.
How the conversion works
The converter draws your GIF onto an HTML canvas element, which captures the first frame. It then encodes that canvas as WebP using the browser’s built-in toDataURL('image/webp', quality) API. The quality parameter (0–100) controls how aggressively the encoder compresses:
- Higher quality = more detail retained, larger file
- Lower quality = more compression, smaller file but may show artefacts on complex images
Transparency from the GIF is passed through as a WebP alpha channel, so transparent backgrounds remain transparent in the output.
No upload happens at any stage — the entire process runs in your browser using local processing. Your original files are never sent anywhere.
Quality setting guide
| Slider value | Best for |
|---|---|
| 60–70 | Simple graphics, icons, colour blocks — barely noticeable loss |
| 80–85 (default) | Most images — large size saving, visually lossless for typical use |
| 90–95 | Photographs or images where fine detail matters |
| 100 | Maximum fidelity, but file size approaches the original |
A setting of 85 is a reliable default for web use. Drop it to 70 for thumbnails and simple graphics; raise it toward 90–95 for any image where quality is critical.
Practical example
A 600×400 GIF product banner at 480 KB:
- Set the quality slider to 85
- Drop the file onto the box
- Download the WebP — typically 120–200 KB for this type of image, a saving of 60–75%
The resulting WebP displays identically in every modern browser (Chrome, Firefox, Edge, Safari 14+).
When to use a different tool
- Animated GIFs — this tool produces a still from the first frame. To convert an animated GIF to animated WebP, use a dedicated tool like
gif2webp(command-line) or an online converter that handles animation. - Lossless output — this tool produces lossy WebP. If you need pixel-perfect lossless compression (e.g. for source assets), use a tool that generates lossless WebP or PNG instead.
