ASF to 3G2 Converter
Processing entirely on your device — large files may take a moment.
Converting 3G2 to MP4 rescues old phone videos for modern screens. If your files are still in ASF format, this page is the shortcut: ASF is Microsoft's streaming container from the Windows Media era — the box that WMV video and WMA audio usually ship in.
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 ASF format
ASF (Advanced Systems Format) is Microsoft's streaming container from the Windows Media era. WMV video and WMA audio live inside it, often with DRM in its commercial life. It carries the same 188-packet-ish streaming DNA as other late-90s containers, plus Microsoft-specific metadata and marker tracks.
Outside Windows it is effectively unreadable without special tools. The exit strategy is MP4: video re-encodes to H.264, audio to AAC, and the file joins the modern world. ASF files carrying DRM-protected streams remain locked — only unprotected content converts.
+ Strengths
- ✓Native Windows Media streaming container
- ✓Holds WMV/WMA with rich metadata
! Limitations
- −Non-Windows support is poor
- −DRM-protected files are locked
About the 3G2 format
3G2 is the 3GPP2 variant of the mobile video format family, born on CDMA networks (Verizon, KDDI) where 3GP ruled GSM sides. Structurally it is a cousin of MP4 carrying H.263 or H.264 baseline video with QCELP/EVRC or AMR audio.
It shares 3GP's fate: low-resolution clips trapped on old phones. Conversion to MP4 is lossless in spirit — the pixels simply move into a container every modern device accepts.
+ Strengths
- ✓Tiny files for its era
- ✓Structurally close to MP4 — clean conversions
! Limitations
- −Low resolution and quality ceiling
- −Obsolete outside old CDMA phones

Frequently asked questions
Is this ASF to 3G2 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 ASF to 3G2?
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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of 3G2, staying in sync with the video. If your ASF file has multiple audio tracks, the first one is used.
