How do I generate SRT subtitles for free?

Upload an audio or video file (or paste a YouTube link) into Txtify, pick a Whisper model, and export a timed .srt file. Txtify is free and open source; you can use the live demo or self-host it with Docker.

What subtitle formats can Txtify export?

Txtify exports SRT, VTT and SBV subtitle files, plus plain TXT and PDF.

Can I translate the subtitles into another language?

Yes. Txtify can translate the transcript into 30+ languages with DeepL before exporting the subtitle file. DeepL is optional and is the only external service Txtify calls.

How to make an SRT file in 3 steps

1. Add your media. Upload an audio/video file or paste a YouTube URL.
2. Pick a Whisper model. Larger models are more accurate; smaller ones are faster.
3. Export .srt. Download the timed subtitles — or choose VTT, SBV, TXT or PDF.

What an SRT file looks like

SRT is a plain-text format: a sequence number, a start → end timestamp, and the caption text. Txtify produces exactly this, aligned to the audio with Whisper via stable-ts:

1
00:00:00,000 --> 00:00:03,400
Welcome to the recording.

2
00:00:03,400 --> 00:00:07,120

Why Txtify for subtitles

Free and open source (Apache 2.0) — no watermarks, no per-minute fees.
Accurate timings — stable-ts gives word-aligned Whisper output, so cues land on the right words.
Private — self-host and your media never leaves your server. The only optional external call is DeepL translation.
Multiple formats — SRT, VTT and SBV for different players and platforms.

Honest note: Txtify exports subtitles but doesn't include a visual subtitle editor for hand-tweaking each cue, and it doesn't label speakers yet. If you need an in-browser editor, Whishper is built for that. For fast, accurate SRT generation with optional translation, Txtify is the quicker path.
