What is TTML (Timed Text Markup Language)?

TTML (W3C Timed Text Markup Language) is an XML-based subtitle format used in professional broadcast and streaming workflows. Netflix uses TTML for its internal caption delivery (often called IMSC or EBU-TT-D). DFXP (Distribution Format Exchange Profile) is an earlier TTML dialect used by some enterprise video platforms. EBU-TT is the European Broadcasting Union's TTML profile, widely used in broadcast TV across Europe. All three share the same core XML structure: a <tt> root element, a <body> section, and <p begin="…" end="…"> elements for each subtitle cue.

Why convert TTML to SRT?

TTML is ideal for delivery but difficult to work with in everyday tools. Video editors (Premiere Pro, DaVinci Resolve), most subtitle editors, YouTube, Vimeo, and the majority of video tools and platforms do not accept TTML directly. SRT is the universal format they all support. Converting TTML to SRT gives you a file you can immediately edit, translate, or upload anywhere. This converter handles TTML, DFXP, and EBU-TT files — all are parsed using the same XML structure.

What gets preserved in the conversion?

The converter preserves subtitle text content and timing (begin/end timestamps) exactly. TTML-specific features — custom fonts, colours, positioning, region definitions, and style attributes — are stripped because SRT does not support them. <br/> elements in the TTML are converted to line breaks in the SRT output. HTML entity references (&, <, etc.) are decoded to their actual characters.

1
Upload or paste your TTML file
Click the upload zone to select a .ttml, .dfxp, or .xml file, or paste the raw XML content into the text box.
2
Click Convert TTML → SRT
The tool parses the XML, extracts all <p> elements with begin/end attributes, and outputs numbered SRT blocks with standard timestamps.
3
Download the SRT file
Click "Download .srt file". The output is compatible with Premiere Pro, DaVinci, YouTube, Vimeo, and all major subtitle tools.

What TTML variants does this converter support?▼

The converter supports standard W3C TTML, DFXP (Distribution Format Exchange Profile), EBU-TT, EBU-TT-D, and IMSC 1.0/1.1. All are XML-based and use <p begin="…" end="…"> elements for cues.

What timestamp formats does TTML support?▼

TTML supports several timestamp formats: HH:MM:SS.mmm (clock time, most common), offset expressions like "1.5s" or "1500ms", and SMPTE timecode with frame counts. This converter handles all common formats.

Is Netflix TTML supported?▼

Netflix uses IMSC (a TTML profile) for caption delivery. IMSC files are valid TTML and will parse correctly. Note that Netflix IMSC files often use region-based positioning — the text content is extracted but position/region data is not preserved in SRT.

Can I convert DFXP files?▼

Yes. DFXP is a TTML dialect. Change the file extension to .xml or .ttml if the uploader doesn't accept .dfxp, or paste the content directly.

Does my file get uploaded to any server?▼

No. Parsing is done entirely in your browser using the built-in DOMParser API. Your file never leaves your device.

Will the SRT work for Netflix or YouTube upload?▼

SRT files converted from TTML will work for YouTube subtitle uploads. Netflix does not accept external SRT uploads from content creators — they use their own delivery pipeline. For standard platform uploads (YouTube, Vimeo, Wistia), the converted SRT is fully compatible.
