F4V to 3GP 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. Rescuing old phone videos means converting 3GP to MP4 before the memories become unreadable.
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 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+ Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
! Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it

Frequently asked questions
Is this F4V to 3GP 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 3GP?
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 3GP 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 3GP, staying in sync with the video. If your F4V file has multiple audio tracks, the first one is used.
