Drop SMI (SAMI) 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 SRT, or download everything as one ZIP if you converted several files.
The SMI to SRT 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.
SMI is HTML-like and many players outside Windows and Korea do not read it. SRT is accepted by practically every player, site and editor. SMI is at home in subtitles for Korean-market players and multilingual files; SRT is the usual choice for subtitles that must work almost everywhere.
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. A SAMI file can hold several languages; only the first one found is read. Positioned lines are written with {\an} codes, which many players honour; players that do not simply show them at the bottom.
SAMI is an HTML-like subtitle format from Microsoft, with each cue a SYNC tag holding the start time in milliseconds. It can hold several languages in one file, selected by style class. It is most common in South Korea.
Opens in Windows Media Player, KMPlayer, PotPlayer, VLC and Korean-market players
SMI converterSRT is the plain subtitle format nearly every player accepts: a number, a time range such as 00:01:02,500 --> 00:01:04,000 and one or two lines of text. It has no official specification and only basic styling, which is why it travels so well.

No. The SMI to SRT 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: SRT 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 SMI file, press Convert and save the SRT. 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.
