How to convert MOV to ASS

  1. Add your MOV videos

    Drop MOV (QuickTime) 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.

  2. ASS is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab and can take a while for large files.

  3. Download

    Save the result. When one file produces several ASS files they come as a single ZIP.

Why ToAny

  • Private by construction

    The MOV to ASS converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

MOV to ASS: what to expect

MOV does not play reliably on Windows, Android, smart TVs or in many upload forms. ASS gives full control over how subtitles look. MOV is at home in recording and editing on Apple devices; ASS is the usual choice for anime and karaoke subtitles with fonts, colours and positioning.

One MOV can produce several ASS files; when it does, they are offered together as a ZIP download. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.

This pair uses the compatibility engine, ffmpeg built for the browser, because ASS cannot be written by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB. Only text subtitle tracks stored inside the video are extracted, one ASS file per track (several tracks come as a ZIP); picture-based tracks from DVDs and Blu-rays are refused because they would need text recognition. A feature-length file is fine, since the video is only read and the result is a few kilobytes.

MOV vs ASS

MOV

QuickTime video

MOV is Apple's QuickTime container and what iPhones and Macs record. MP4 was based on it, so the two are close relatives and often hold exactly the same video and audio streams inside.

Opens in Apple devices and video editors; Windows and Android are hit and miss

MOV converter
ASS

ASS/SSA subtitles

ASS adds styles to subtitles: fonts, colours, outlines, shadows, exact screen positions and animation effects. Fan-subbed anime and karaoke use it heavily. SSA is the earlier version, and the .ssa extension is read as the same format.

Opens in VLC, mpv, Aegisub and most fan-subtitling and media-server software; not browsers

Questions

Are my videos uploaded anywhere?

No. The MOV to ASS conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting MOV to ASS?

The content is carried over as faithfully as ASS allows; features that ASS does not have are left out.

Can I convert several MOV files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert MOV to ASS on Windows, Mac, iPhone or Android?

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 MOV file, press Convert and save the ASS. There is nothing to install.

Is there a file size limit?

Yes. MOV to ASS runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
