Convert FLV to MOV — Free & Private
FLV (Flash Video) files are digital fossils from the web's Flash era — YouTube used the format until around 2012, and countless learning platforms, news sites, and video archives stored content in FLV. Adobe ended Flash Player on 31 December 2020, making FLV files permanently unplayable in any modern browser without conversion. Downloaded web video, archived course content, and early streaming captures are the most common sources. Converting to MOV makes the file native to Apple's QuickTime ecosystem, importable directly into Final Cut Pro and iMovie, and compatible with Mac without a codec step. MOV with H.264 or H.265 maintains excellent quality at moderate file sizes.

Key Questions About FLV to MOV, Answered
Direct answers structured for AI extraction, voice search, and featured snippets.
Will my video be re-encoded or just remuxed when converting FLV to MOV?
It depends on the codec inside your FLV. Most Flash Video files made after 2008 carry H.264, which QuickTime's MOV container supports directly — so Convertlo can remux that video into MOV in seconds with zero quality loss. Older FLVs encoded with VP6 or Sorenson H.263 aren't supported by MOV at all, so those have to be re-encoded to H.264 first.
- H.264-in-FLV → MOV: fast remux, no quality loss
- VP6/Sorenson-in-FLV → MOV: re-encoded to H.264, with a small generation loss
- If you're unsure which type your FLV is, Convertlo detects it automatically and picks the right path
Will the output MOV open in QuickTime, iMovie, and Final Cut Pro?
Yes — that's the appeal of MOV over MP4 for Mac users. An H.264 MOV drops straight into iMovie or Final Cut Pro for editing and opens natively in QuickTime Player, while still playing fine in VLC or Windows Media Player if you need to share it elsewhere.
- macOS/iOS: MOV is QuickTime's native format, opens without conversion
- Final Cut Pro / iMovie: import the converted MOV directly
- VLC and Windows players: handle H.264 MOV just as well as MP4
How much will the file size change going from FLV to MOV?
If your FLV is H.264 and gets remuxed, the file size stays almost exactly the same — only the container changes. If it's an older VP6/Sorenson FLV that needs re-encoding, the resulting H.264 MOV is often smaller, since H.264 compresses more efficiently than those older Flash-era codecs.
- H.264 FLV → MOV (remux): file size essentially unchanged
- VP6/Sorenson FLV → MOV (re-encoded to H.264): typically smaller at comparable quality
- Container choice (MOV vs MP4) makes almost no difference to file size either way
Will the converted MOV from FLV work in iMovie or Final Cut Pro for editing?
Yes — an H.264 MOV opens directly in both iMovie and Final Cut Pro X without any intermediate step. FLV itself is rejected by both apps; converting to MOV is the standard workflow for bringing old Flash video into an Apple editing suite.
- iMovie: H.264 MOV imports natively — drag it straight into the project browser
- Final Cut Pro X: imports H.264 MOV without transcoding; use Optimize Media for smoother scrubbing on long clips
- FLV to MOV always involves a re-encode — FLV's codecs are not QuickTime-native
