Free subtitle & transcript tools

A handful of browser-based tools for subtitle and transcript files (SRT, WebVTT, plain text). No account, nothing uploaded to a server: everything runs locally in the tab you're looking at. Use them to get subtitles ready for a video player, switch formats for an editing workflow, or pull clean text out of a captioned video.

Why browser-based subtitle tools?

There's no queue and no paid tier — drop a file and the conversion runs immediately, even for a subtitle track two hours long. The parsing and conversion happen client-side in JavaScript, so your file never leaves the browser tab and there's nothing for a server to log or store.

No sign-up, no email confirmation, nothing to manage afterward. Open the page, drop the file, download what comes out. Works the same on desktop and mobile.

Need a transcript first?

If you've got audio or video but no subtitles yet, convert.express can generate a transcript with AI. Upload an MP3, MP4, WAV, or similar file and get text back in seconds, with SRT and VTT export built in. 10 minutes free every day, no subscription.
