Summary
Upload a GIF and download it as AVIF — or WebP if your browser does not support AVIF encoding. First frame only, processed entirely in your browser.
How it works
- Select or drag-and-drop a GIF file onto the upload area.
- The tool reads the GIF using the browser's built-in Image API.
- The first frame is drawn onto an off-screen HTML Canvas element.
- The canvas attempts export as AVIF using the native toBlob API.
- If AVIF encoding is unsupported, it falls back to WebP automatically and notifies you.
- A download link is generated so you can save the converted file.
Use cases
- Reduce GIF file size by converting the first frame to modern AVIF format.
- Extract a static preview image from an animated GIF as AVIF.
- Convert GIF thumbnails to AVIF for faster web page load times.
- Prepare images for platforms that require AVIF or WebP format.
- Replace heavy GIF assets with lightweight AVIF static images.
- Get a static AVIF poster frame for use alongside a video or animation.
