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.
SRT to TXT Converter
Strip timestamps and formatting from an SRT file and download clean plain text.
VTT to SRT Converter
Convert WebVTT (.vtt) files to SRT: the format most video players and editors expect.
SRT to VTT Converter
Convert SRT files to WebVTT (.vtt): what HTML5 video, YouTube, and browser players actually need.
Subtitle Timestamp Shifter
Shift every timestamp in an SRT or VTT file by any number of seconds. Fixes out-of-sync subtitles instantly, right in your browser.
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.
