Frequently asked questions

WebP conversion, animated WebP from video, and how local browser processing works.

What is image2webp?
image2webp is a free browser-based tool to convert common image formats to WebP and to build animated WebP files from short videos. Processing uses WebAssembly so your files stay on your device.
Which image formats can I convert to WebP?
You can select typical raster images your browser can decode, such as PNG, JPEG, GIF, and other image/* types supported by the file picker. Output is always WebP.
How can I convert an image to WebP for free?
Choose one or more JPG, PNG, GIF, or similar image files, then start the conversion in your browser. image2webp is a free image to WebP converter, and processing happens locally without uploading your files.
Is this also an img to WebP converter?
Yes. People search for both "image to WebP" and "img to WebP", and this tool supports both use cases: converting common image files like JPG and PNG into WebP directly in the browser.
How does video to WebP work?
The tool samples frames from your video and encodes them as an animated WebP, not a video file. Long clips are limited by max frames, FPS, and resolution settings to keep files reasonable and encoding fast.
Are my files uploaded to your servers?
No. Conversion runs locally in your browser. We do not receive your images or videos for processing. See the Privacy page for details on hosting logs.
What WebP quality should I use?
Quality is on a 1-100 scale. Values around 75-85 are a good balance of size and visual quality for photos and UI assets. Lower values shrink files more but may show more compression artifacts.
Can I use it offline?
After the first visit, cached assets may allow limited offline use depending on your browser and cache. A network connection is usually required to load the app and WASM the first time.
Will animated WebP play everywhere?
Animated WebP is widely supported in modern browsers. Some older clients or email clients may not animate WebP; use previews in your target environments when it matters.
