TTML to SRT Converter


TTML and DFXP files are the professional standard for broadcast captions and streaming subtitles. Netflix, Amazon Prime, and major broadcasters use these XML-based formats. Our converter transforms these complex timed text files into simple, universal SRT format that works everywhere.


How the TTML to SRT Converter works


Upload your TTML, DFXP, or XML subtitle file from professional captioning software or streaming platforms. The converter parses the complex XML structure, extracting timing and text information while preserving proper formatting. Region and style information is intelligently converted to work in SRT format. Download your SRT file ready for any video player or editing software.

TTML conversion bridges professional and consumer worlds. Broadcasters make their captions universally compatible, streaming services provide downloadable subtitles, and video editors work with simpler formats. The XML complexity of TTML is powerful but overkill for most uses – SRT gives you the same text and timing in a fraction of the size.
