Common errors & troubleshooting
Browser cannot decode WebP
Cause: Your browser lacks a decoder for this WebP variant.
Fix: Try another browser, or convert on a device that supports the codec.
Blank or corrupted preview
Cause: The file may be truncated, password-protected, or not a real image.
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 output support is browser-dependent; where native encode is unavailable, UtilityKit documents the limit honestly.
- 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.
