FLV to MOV Converter
Processing entirely on your device — large files may take a moment.

Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the FLV format
FLV (Flash Video) was the video format of the early streaming web — YouTube's original delivery container from 2005 to ~2010, played by Adobe Flash Player. Later versions carried H.264/AAC, but the container lived and died with Flash, which reached end-of-life in 2020.
Modern browsers cannot play FLV at all, and only niche players (VLC) bother. If you have an FLV archive, converting to MP4 recovers the same H.264 video into a container every device accepts.
+ Strengths
- ✓Only relevant for early-web video archives
! Limitations
- −Dead ecosystem — Flash ended in 2020
- −No browser support at all
About the MOV format
MOV is Apple's QuickTime container, and technically the elder sibling of MP4 — same ISO base media format, same codec freedom. What sets it apart is professional video: ProRes intermediate codecs, timecode tracks and alpha channels live in MOV, which is why Final Cut, Premiere and every camera that shoots Apple ProRes hand you MOV files.
For everyday sharing it behaves exactly like MP4 (an H.264 MOV is interchangeable in practice). Where it hurts is size: ProRes and other editing codecs run hundreds of gigabytes per hour by design — they prioritize frame-accurate editing over compactness.
+ Strengths
- ✓Native to macOS, iOS and pro editing suites
- ✓Carries ProRes, alpha and timecode tracks
- ✓MP4-compatible for standard codecs
! Limitations
- −Editing codecs produce enormous files
- −ProRes playback needs capable hardware/players

Frequently asked questions
Is this FLV to MOV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for FLV to MOV?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Does converting FLV to MOV re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
