Troubleshooting
Audio conversion stopped because browser memory ran out
Browser FFmpeg holds source, decoded data, and output in memory, so peak use can be several times the compressed file size.
Reviewed against current browser behavior and AudioFetcher test fixtures on July 28, 2026.
Check these first
- 1
Compare compressed file size with available device memory.
- 2
Check whether the source is long uncompressed PCM or video.
- 3
Close background tabs and applications.
- 4
Try the same task on desktop.
Reliable fixes
- Split the source into shorter sections.
- Use a lower-memory desktop workflow for multi-hour or high-resolution media.
- Do not repeatedly retry on a memory-constrained phone.
Change one variable at a time and test with a short known-good file. That separates a damaged source from a browser, codec, or memory limitation.
