- Metadata and interactive elements may need a manual review after processing.
- Server processing accepts files up to 100 MB; very large batches may need to be split.
- Complex files may take longer and can hit processing time limits.
Platform compatibility
MP3 works in all current major browsers. Open the result in the app where it will be used, and keep the source AUDIO/* for comparison.
When not to convert
- Do not overwrite the source; keep both versions until the output has been approved.
- Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
- If the file contains sensitive data, review the processing model before uploading it to a server.
