Convert MP4 to Text Online
MP4 is a video container — and you can drop it here as-is, up to 1 GB. The audio track is extracted right in your browser, so the video itself never leaves your device. Upload it and get an accurate transcript plus every subtitle format in seconds.

1 upload = every format
One transcription returns TXT, SRT, VTT, ASS, SSA, MicroDVD, MPL2 and TMP — download one or grab the ZIP.
93 languages, auto-detected
The spoken language is recognized automatically among 93 languages, and the finished transcript translates into any of 110 languages for free.
Private by design
Audio streams through without being stored; server copies of the text are erased within 1 hour. Your history lives in your browser.
Editable result
Fix or delete any line in the built-in player — every subtitle format and download updates instantly.
Subtitle lines, not blocks
The engine returns 30-second blocks. We re-cut them on the pauses in the speech, within the length and reading-speed limits subtitles are held to.
The video stays with you
MP4, MOV, MKV, WebM, AVI up to 1 GB — the audio track is extracted in your browser, so only sound is ever uploaded.
Your video never leaves your device
The audio track is extracted locally, right in your browser — only the sound is uploaded for recognition. A 1.5 GB lecture becomes a ~40 MB audio file before anything touches the network, which is faster and far more private than uploading video to a converter site.
Frequently asked questions
How do I convert MP4 to text?
Drop the MP4 file on the upload area (or click to pick it), press Start Transcription and copy or download the result. No account is needed for your first 2 files.
Can I get subtitles instead of plain text?
Yes — the same upload produces SRT, VTT, ASS, SSA, MicroDVD, MPL2 and TMP alongside the plain transcript, at no extra cost.
How much does it cost?
Your first 2 files are free with no account, and a free account gives you 3 every month. After that, plans start at $2/month for 20 transcriptions — every subtitle format and free translation are included in each one.
Are my files stored anywhere?
No. Audio streams straight through to the recognition engine and is never written to disk; transcript texts are erased from our servers within 1 hour. Your lasting copy stays in your own browser.
