F4V to ALAC Converter
Processing entirely on your device — large files may take a moment.
F4V is Adobe Flash Player's later H.264-based video container — same essence as MP4, delivered through the Flash era. Convert ALAC to FLAC for non-Apple players, or MP3 for sharing.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the F4V format
F4V is Adobe's later Flash Video container, introduced when Flash Player gained H.264 support around 2007. Internally it is an ISO-base-media file — the same family as MP4 — so an F4V is essentially an MP4 with a different extension and Flash-era metadata.
Conversion to MP4 is a container change, not a re-encode: the H.264 video and AAC audio pass through intact. That makes F4V→MP4 one of the cleanest conversions in the whole format zoo — quality is byte-identical.
+ Strengths
- ✓Modern H.264/AAC inside
- ✓Converts to MP4 without quality loss
! Limitations
- −Dead ecosystem (Flash ended in 2020)
- −Some players dislike the extension
About the ALAC format
ALAC (Apple Lossless Audio Codec) is Apple's FLAC equivalent: bit-exact lossless compression inside an MP4 container, opened-source in 2011 and now native on every Apple device and most server-side pipelines. It is what iTunes Store sells as "lossless" and what iPhone recordings encode to by default.
For non-Apple players FLAC is the safer target, and conversion is sample-exact in both directions — the decode is handled by ffmpeg's native ALAC decoder without any Apple runtime.
+ Strengths
- ✓Native on every Apple device
- ✓Open source since 2011
- ✓Reasonable sizes inside MP4
! Limitations
- −Outside Apple ecosystems FLAC wins
- −Slightly worse ratios than FLAC
- −Confusing .m4a extension doubles as lossy
Why convert F4V to ALAC?
Converting makes sense where the strengths of ALAC meet what F4V cannot give you. Native on every Apple device Meanwhile Dead ecosystem (Flash ended in 2020) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this F4V to ALAC 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 F4V to ALAC?
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.
Does converting F4V to ALAC 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of ALAC, staying in sync with the video. If your F4V file has multiple audio tracks, the first one is used.
