Technical details
Browser-local FFmpeg WebAssembly worker, Canvas and Web Audio. Single-worker fallback does not require SharedArrayBuffer. Files are not retained after reload.
How to use this tool
- Choose your source file using the labeled file button.
- Review metadata, preview and the relevant destination settings.
- Start processing and keep this page open.
- Download or share your finished file from the completion dialog.
Supported files and device limits
Common audio inputs include MP3, WAV, FLAC, M4A/AAC, OGG and Opus when the bundled engine can decode the codec. Images: JPEG, PNG and WebP. Convert HEIC to JPEG first. Large sources, long podcasts and 4K exports can exceed browser memory. Try a shorter clip or lower resolution if an export fails.
Privacy and troubleshooting
Source media stays in this browser session. The engine downloads from jsDelivr on first use; the provider receives ordinary connection information but no source media from these tools. Only non-sensitive destination preferences are saved locally. Retry after an engine error, close memory-heavy tabs or try a different browser. No higher-resolution setting can restore detail absent from your source.
Accessibility
Controls have text labels, timelines use numeric time fields, and downloads open in a keyboard-accessible dialog. Accessibility information and issue reporting.
