Use a copy. Review the result.

Permitted files

Use subtitles you own or are authorized to process. This website does not supply film or television subtitle libraries and does not determine whether you have permission to distribute a file.

Scope of the service

The tools provide structural checks and deterministic changes for a supported subset of SRT and WebVTT. They cannot establish transcript accuracy, accessibility compliance, synchronization with audio or acceptance by a delivery platform.

Review before relying on an export

Keep the original, review warnings and compare the new file against the final video. Format conversion can remove information and timing policies can trim or remove cues. These effects are described in the tools and reports.

Availability

This independent utility is provided as available, with no guarantee of uninterrupted operation or suitability for a particular delivery specification. These terms do not exclude rights that applicable law does not permit to be excluded.
