Word to SRT — From Document to Timed Captions

Paste text from Word or any editor and get a timed SRT — smart quotes cleaned up, sentences cued, paced to read.

Quick answer: Copy the text from your document and paste it into the box: quotes and dashes are normalised, sentences become cues timed at your chosen reading speed, and you download a standard .srt — the document itself is never uploaded.

Drop a .txt transcript — or paste below. The file never leaves your device.

What this tool does

Scripts written in word processors carry invisible luggage: curly quotes, en-dashes, non-breaking spaces, list markers. Pasted into a plain subtitle pipeline they either survive as encoding artefacts or break parsing. This converter cleans them to plain ASCII as it splits your text into sentence-sized, timed cues — the same pacing engine as the plain-text converter, tuned for the way documents are actually written. It deliberately works by paste: Word files themselves are ZIP containers with layout, and the words are all a subtitle needs.

Common uses

  • A voice-over script in Word becomes captions for the finished video
  • A interview transcript in Google Docs becomes a caption draft
  • Lyrics or poetry documents turned into readable cue cards

Frequently Asked Questions

Why can't I upload the .docx directly?
A .docx is a ZIP archive of XML describing layout, fonts and revision history — heavy machinery to unpack in a browser for what is ultimately paragraphs of text. Paste is instant and gives the same result: your words, timed.
What gets cleaned from the pasted text?
Curly quotes become straight ones, en/em-dashes are kept but non-breaking and soft-hyphen characters are normalised, and list bullets or numbering that would confuse sentence-splitting are left visible so you can delete them deliberately.
Does the timing reflect the actual narration?
No — it is an estimate from text length, useful as a starting draft. If your document includes timestamps next to paragraphs, use the TXT to SRT converter, which reads them exactly.
