Drop TTML (DFXP) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the MCC, or download everything as one ZIP if you converted several files.
The TTML to MCC converter is part of this page and runs inside your browser. Your subtitles are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
TTML is verbose XML that many consumer players cannot read. MCC is accepted by broadcast delivery specifications and caption tools that need frame-accurate caption packets. TTML is at home in subtitles delivered to broadcasters and streaming services; MCC is the usual choice for closed captions for broadcast and streaming delivery that carry CEA-708 as well as CEA-608.
The text is read as UTF-8 or UTF-16, whichever the file is. An older file in another code page is read using the charset it declares, or as Windows-1252 if it declares none, so accented letters in an unlabelled legacy file can come out wrong. A file that is not text, such as the picture-based subtitles of a DVD, is refused instead of being converted to nonsense. Of the styling, only italic, bold, underline and the position on screen (top, middle or bottom, left, centre or right) travel between formats; fonts, colours, outlines and effects do not. Times in clock, offset, frame and tick form are all understood, and a region's position is kept as the cue's position. The captions are the same CEA-608 pop-on data as an SCC file, wrapped in one caption packet per frame that carries data. Idle frames get no line, which keeps the file small, and there is no CEA-708 data.
TTML is the W3C's XML subtitle format. Streaming services and broadcasters deliver captions in TTML profiles such as IMSC. It can describe regions, styles and timing precisely, but it is verbose, and many consumer players do not read it. DFXP is an earlier profile of it.
Opens in Broadcast and streaming systems, Apple and Netflix workflows, and some video players
TTML converterMCC is MacCaption's caption file: one line per video frame, each a caption distribution packet in hexadecimal that can hold both CEA-608 and CEA-708 data. It exists so that captions can follow the video's own frame rate, 24 to 60 fps, and so that one file serves analogue and digital caption decoders.
Opens in MacCaption, CaptionMaker, Premiere Pro, Final Cut Pro and DaVinci Resolve

No. The TTML to MCC conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: MCC stores the decoded audio exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the TTML file, press Convert and save the MCC. There is nothing to install.
Yes, but a subtitle file is small. Files up to 50 MB are accepted, far more than any real subtitle file. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
