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

- ✓Plays on old feature phones
! Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it
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

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