Common errors & troubleshooting
Browser cannot decode AVIF
Cause: Your browser lacks a decoder for this AVIF variant.

Fix: Re-export the source image and try again with Load example if available.
Privacy and security
- Your input and generated output are processed locally and are not sent to our servers for tool execution.
- Opening a local file uses the browser File API; the file is not uploaded to UtilityKit.
- We may collect anonymous product analytics (for example page views). Tool contents are not included in those events.
- AVIF decoding depends on your browser; unsupported files show a clear error instead of a silent failure.
- Conversion runs entirely in your browser using Canvas and Web APIs when the format is supported.
- Animated sources may export a single frame unless the tool explicitly supports animation.
