FAQ

Frequently Asked Questions (FAQ)

How do I convert an SRT file to VTT online?: Upload your .srt file above, choose VTT as the output format, and click Convert. Editsub rewrites the file to WebVTT while keeping every timestamp and line of text, then lets you download the converted .vtt file instantly.
Is this subtitle converter free to use?: Yes. The subtitle converter is completely free and requires no account or installation. You can convert as many files as you like directly in your browser.
Which subtitle formats can I convert between?: Editsub converts between SRT, VTT, ASS, SSA, and SBV. You can convert in any direction - for example SRT to VTT, VTT to SRT, or ASS to SRT.
Does converting keep my subtitle timing and text?: Yes. Only the file format changes - the start and end timestamps and the subtitle text stay exactly as they were, so your converted subtitles remain in sync with the video.
Can I convert multiple subtitle files at once?: Yes. Batch conversion is supported: upload several subtitle files together, convert them in one run, and download the results individually or as a ZIP archive.
What is the difference between SRT and VTT?: SRT is a simple, widely supported subtitle format with plain text and timestamps. VTT (WebVTT) is built for the web and the HTML5 video player, adding optional styling, positioning, and metadata. Use SRT for the broadest compatibility and VTT for web video.
