Press Convert. There is nothing else to set. The work happens in this tab.
Save the SCC, or download everything as one ZIP if you converted several files.
The EBU-STL to SCC 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.
EBU STL is a binary file that web players and most consumer apps cannot read. SCC is what broadcasters, DVD authoring tools and video editors accept as closed captions. EBU-STL is at home in subtitles delivered to European broadcasters; SCC is the usual choice for closed captions for US and Canadian broadcast, DVD and some streaming deliveries.
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. Only Latin-alphabet EBU STL files are read. Colours, boxes and double-height text are dropped; italics, underline, line breaks, position and justification are kept, and times are shifted back by the programme start the header declares. Captions are written as CEA-608 pop-on captions on channel CC1 at 29.97 fps drop-frame: lines are wrapped to 32 characters and at most four rows, characters the standard has no code for become the nearest plain letter or a question mark, and colours are not kept. A caption needs a moment to load, so cues closer together than that are painted on as they are typed or appear a few frames late. Input denser than the channel can carry (a byte pair a frame) loses the captions that could not start within two seconds of their time, and a cue that starts while another is showing cuts that one short.
EBU STL, defined in EBU Tech 3264, is the binary subtitle file of European broadcasters: a 1024-byte header followed by 128-byte blocks, each holding the in and out timecodes, position, justification and teletext-style text of one subtitle. It is usually named .stl, which is also the extension of 3D printing files, so ToAny tells them apart by the header inside.

EBU-STL converterSCC stores the CEA-608 caption data of line 21 video as lines of hexadecimal byte pairs, each line starting at a timecode, one pair per video frame. It is limited to 32 characters on up to four rows, a Latin character set and a frame-based clock (usually 29.97 fps drop-frame), but it is what American broadcasters and many video editors expect.

No. The EBU-STL to SCC 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: SCC 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 EBU-STL file, press Convert and save the SCC. 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.
