How do I convert TTML to SRT?

Add your .ttml, .dfxp or .xml file, keep SRT selected and download it. You can also turn TTML into VTT, ASS, SBV, TXT or JSON.

What is the difference between TTML and DFXP?

DFXP (Distribution Format Exchange Profile) was the name of TTML before it became a W3C standard. The files are the same kind of XML, and both convert here.

Can I convert XML subtitles?

Yes, when the XML is TTML or DFXP, which most subtitle .xml files are, or YouTube's timed text XML. Other XML files, such as editing project files, hold no subtitle times the converter can read.

Why are the times in my file numbers like 241910001t?

Those are ticks. Many TTML files count time in ticks, often ten million a second. The converter reads the tick rate the file declares and turns each time into a normal SRT time.

Italic, bold and underlined text stays that way, whether it is set on the line or in a named style. Colours, fonts and positions are left out, because SRT has no standard way to show them.

Are my files uploaded?

No. The conversion runs in your browser, so your subtitles stay on your device.

TTML Files

What is a TTML file?

TTML (Timed Text Markup Language) is the W3C caption format used by streaming services and broadcasters. Its earlier name is DFXP, and many TTML files simply end in .xml. Each line is a paragraph with a begin and end time, and styles such as italics are set on the line or defined once at the top.

Video editors, players and most upload forms want SRT instead. The converter reads the times however they are written and keeps the text and its styling.

Every kind of time

Clock times, frames, ticks and seconds all convert, using the frame and tick rates the file declares.

Styles kept

Italic, bold and underline come through, from the line itself or from styles defined at the top of the file.

Lines put together

Some files give each line of a subtitle its own paragraph with the same times. They become one subtitle with two lines.

YouTube XML too

YouTube's timed text XML converts as well, and automatic captions that overlap are trimmed so each ends where the next begins.
