MOV to TS Converter
FileFlip converts MOV to TS entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a MOV file to TS?#
- Drop your MOV file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to TS and the conversion starts on its own. FileFlip usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, then runs WebCodecs and FFmpeg on your own machine.
- Save the TS file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting MOV to TS lose quality?#
Sometimes. When the codecs inside the MOV file are ones the TS container can hold, the streams are copied straight across and nothing at all is lost. When they are not, the file has to be decoded and encoded again, and that step does cost a little quality.
Is it safe to convert MOV files online?#
Yes, because nothing is uploaded. FileFlip converts MOV files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What MOV to TS actually does to the file#
Converting MOV to TS runs on WebCodecs and FFmpeg, usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, copies the streams through when the codecs fit and re-encodes when they do not.
| Engine | WebCodecs and FFmpeg |
|---|---|
| Conversion path | One step: MOV → TS |
| Downloaded to your browser | Nothing in most browsers, or 30.8 MB if yours cannot encode these codecs itself |
| Quality | Lossless when the codecs fit, lossy when they do not |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Encoded streams | Sometimes | Survives for some files and not others. |
Worth knowing before you start:
- the FFmpeg fallback is an LGPL build, so a re-encode produces MPEG-4 Part 2, VP8, VP9, or Theora rather than H.264 or H.265
- whether the browser can do this without FFmpeg depends on the codecs it exposes through WebCodecs
- the encoded streams are copied when the file's codecs fit the target container, and re-encoded when they do not
What is a MOV file?#
A MOV file holds video, audio, text and timecode as separate tracks in Apple's QuickTime container, the 1991 format whose structure MPEG later adopted as the basis for MP4.
Keep footage as MOV while it is still being edited, especially ProRes, where the point is fast scrubbing and repeated re-encoding would cost quality.
Convert MOV to MP4 once the video is finished and needs to be shared, uploaded or played on Windows and Android.
What is a TS file?#
A TS file carries MPEG transport stream data, the packetized container built for broadcast so a receiver can start decoding correctly at any point after tuning into a channel already in progress.
Keep a recording as TS while it's still being processed by broadcast or streaming tools that expect the transport stream structure, such as a DVR or an HLS pipeline.
Convert TS to MP4 once a recording is done being processed and just needs to play back or get edited, since MP4 drops the broadcast-oriented overhead without losing any video quality.
MOV to TS questions people ask#
Why are MOV files from my camera so large?
Large MOV files are usually ProRes, Apple's editing codec introduced in 2007, which compresses each frame on its own instead of storing differences between frames. ProRes 422 runs around 122 Mbit/s at 1080p and ProRes 4444 around 275 Mbit/s, against maybe 10 to 20 Mbit/s for delivery H.264. You are paying in disk space for footage that edits cleanly and survives being re-encoded.
What is the difference between MOV and MP4?
MOV came first and MP4 was built from it. ISO standardised MP4 in 2001 directly on Apple's published QuickTime file format, so a MOV and an MP4 share the same atom layout internally. The practical difference is what they are allowed to carry: MP4 sticks to a standardised codec list, while MOV also holds Apple codecs like ProRes that MP4 players do not expect.
Why won't my MOV file play on Windows?
Windows has no built-in MOV support because Apple abandoned QuickTime for Windows in April 2016, leaving two known vulnerabilities unpatched and prompting US-CERT to recommend uninstalling it. VLC plays MOV files on Windows without any of that, and converting to MP4 makes the file work in the built-in player. If the MOV holds ProRes, converting is the only realistic option.
Is MOV a codec?
MOV is a container, so whether it plays depends on the codec inside rather than the extension. A MOV from an iPhone usually holds H.264 or HEVC and plays almost anywhere. A MOV from an edit suite may hold ProRes, which needs Final Cut, Premiere, Resolve or VLC, and will simply fail in a browser or on a TV.
