YouTube subtitles, free and ready to upload
Upload your video, download the subtitles as SRT or VTT and add them in YouTube Studio. Subtitles you upload replace YouTube’s automatic ones, which stumble over names and don’t always break sentences well.
Drop your audio or video here, or choose a file
MP3, M4A, WAV, OGG and OPUS (WhatsApp voice notes), MP4, MOV, WEBM… Up to 200 MB.
Free, no account needed: the first 10 minutes of each file, 3 a day. The file is deleted when it’s done and the result after 24 hours.
Which format YouTube accepts
YouTube accepts both: SRT and VTT. Either works; SRT is the simplest. YouTube asks for plain UTF-8 text files without styling, which is exactly what you download here.
Why upload your own
Uploaded subtitles play with the video on any device and help people watching with the sound off. Echo cuts them to industry rules: two lines of 42 characters at most, between 1 and 7 seconds each, and breaks at the end of sentences, at commas or when the speaker changes.
- No account: the first 10 minutes of each video, up to 200 MB and 3 files a day.
- With a free account: whole videos, a subtitle editor and tracks in other languages to upload to YouTube as well.

Frequently asked questions
SRT or VTT for YouTube?
Both work. If you’re not sure, use SRT: it’s the most widely used format and YouTube reads it without any trouble.
Can I upload subtitles in several languages?
Yes, YouTube takes one track per language. With a free Echo account you translate the subtitles into other languages with the same timing and download each track as SRT or VTT.
What if the video is longer than 10 minutes?
Without an account, the first 10 minutes are subtitled. With a free account you upload the whole video, up to 2 GB.
