A few things
worth knowing.
How do I convert SRT to VTT?
Choose your .srt files in the tool, select WebVTT output, then apply your rules. Download a file or export the entire batch as a ZIP.
What changes during conversion?
WebVTT gets a WEBVTT header and uses a period before milliseconds instead of a comma. Text and timing are preserved unless you enable cleanup, reflow or a time shift.
Can I convert several files at once?
Yes. The free version accepts up to 3 files per local day, with a 1 MiB limit for each file.
What does Pro include?
Pro is $6.99/month for more files: no daily file allowance, up to 30 files per workspace, 10 MiB per file and 20 MiB total. Use your checkout email to restore Pro. Checkout is currently disabled; the free toolkit and example work without signing up.
Can I save my processing rules?
Yes. Save your recipe to restore format, shift, line length and cleanup options on your next visit. It stays in local browser storage.
