Subtitles drift out of sync
Captions are consistently early or late, or drift gets worse as playback continues.

Start from a task intent
Convert
Handle subtitle format changes directly in the browser.
Move format work through clean browser-side converters, then pair it with one guide or article lane only when the issue is larger than a format mismatch.
Recommended route map
Convert for browser delivery first, then branch into timing repair, bilingual packaging, or reverse conversion.
SRT to VTT should stay as a clean delivery-format step before the subtitle job widens into more editing work.
Open Subtitle Sync
Repair timing after conversion when the subtitle text is fine but the cue alignment is still off.
Open routeOpen Bilingual Subtitles
Merge source and translated text once the browser-ready subtitle file is structurally stable.
Open routeOpen VTT to SRT
Convert back to SRT when the downstream tool or archive pipeline still requires SRT.
Open routeKeep browser-format conversion connected to timing repair, packaging, and reverse conversion.
- Subtitle Sync Repair timing after the subtitle file is converted for browser playback.
- Bilingual Subtitles Package source and translated text after the structure is stable.
- VTT to SRT Convert back to SRT when the downstream editor or archive still expects SRT.
- Subtitle out of sync Use the guide when the converted subtitle plays at the wrong time.
Common questions before you convert SRT subtitles into WebVTT.
- Common questions before you convert SRT subtitles into WebVTTUse this page to handle web subtitle conversion in the browser before you move into any heavier workflow.
- Can I do this directly in the browser?Yes. This lane is intentionally designed for lightweight browser-side processing so the page can stay fast, indexable, and cheap to operate.
- When should I move to the workspace?Use the workspace only when the job needs a broader workflow, repeated operations, or you need to connect subtitle work with playback and history.
