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 SBV, or download everything as one ZIP if you converted several files.
The TTML to SBV 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. SBV imports directly into YouTube Studio. TTML is at home in subtitles delivered to broadcasters and streaming services; SBV is the usual choice for uploading and downloading YouTube captions.
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. YouTube's SBV has no styling and no positions, so the result holds the text and times only.
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 converterSBV is the plain caption format YouTube exports and accepts: a time range such as 0:00:01.000,0:00:04.000 followed by the text. It carries no styling and few other programs read it.
Opens in YouTube Studio and some caption tools; few media players

No. The TTML to SBV 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: SBV 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 SBV. 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.
