Conversion surface
Run the file task now.
The converter stays fast and simple. Workspace features only step in when retention, OCR, or repeat work actually adds value.
How it works
A short path from input to finished export.
The flow stays simple so you can get in, finish the job, and move on without extra setup.
Upload WebP Files
Drag and drop your WebP images or click to browse. You can queue several files at once.
Adjust Quality
Use the quality slider to balance file size against fidelity. The default of 75% suits most images.
Download AVIF
Save the converted file right away. Multiple images are bundled into a ZIP for one-click download.
Why FileMorf
A cleaner route for this conversion.
The tool keeps the core job lightweight while still giving you room to grow into retained, higher-value workflows later.
100% Private
All processing happens in your browser. Your files never leave your device.
Best-in-Class Compression
AVIF's AV1-based encoding produces the smallest files of any mainstream image format, with transparency support.
Batch Processing
Convert multiple files at once. Download as a convenient ZIP file.

The important questions, plus the nearby routes users usually need next.
If you already serve WebP, AVIF is the next step down in size — often 20-40% smaller again at comparable quality, with the same alpha transparency support. It is worth doing for high-traffic pages; keep WebP as the fallback for older browsers.
Yes. Both WebP and AVIF store a full alpha channel, and FileMorf preserves it exactly — anti-aliased edges, soft shadows, and semi-transparent pixels all survive the conversion.
Slightly, in principle. WebP and AVIF are both lossy formats, and every re-encode discards a little more data — the digital equivalent of photocopying a photocopy. In practice, keeping the quality slider around 85-90% makes the difference imperceptible. Just avoid converting the same image back and forth repeatedly.
Yes — the encoding runs in your browser, and in-browser AVIF encoding is currently available in Chromium-based browsers such as Chrome, Edge, Brave, and Opera. If your browser cannot encode AVIF, FileMorf reports an error instead of silently producing a different format. The finished files display in Chrome, Firefox, Edge, and Safari 16 or later.
Typically another 20-40% below the WebP source at similar quality — a difference worth having on high-traffic pages.
An animated WebP is decoded as its first frame, so the output is a single still image. Static WebP files — the vast majority — convert in full.
