Hi Product Hunt, I'm Viet, a web developer. I built SubtitleMedic because I kept downloading subtitles that were out of sync or full of garbled characters, and every fix meant installing a desktop editor or uploading the file to a site I knew nothing about. SubtitleMedic gives each of those problems its own small tool: shift timing, change frame rate, sync against another file, convert between SRT, VTT, ASS, SBV and SUB, fix encoding, merge two languages, and clean out ads, SDH and formatting tags. Everything runs in the browser tab. The file is read by JavaScript on your device and is never uploaded, so there is no sign-up, no upload limit and no queue, and it keeps working offline after the page loads. The site is free and supported by ads, in English and Vietnamese. I'd love to hear which subtitle problems it doesn't handle yet, so send me any broken file you have.
