How to convert WMV to 3GP
Add your WMV videos

Balanced quality suits most videos. If the codecs already fit 3GP, Fylo repackages the file instead of re-encoding it, with no quality loss.
Convert and download
Click Convert, then download each 3GP file or all of them as one ZIP.
Why convert WMV to 3GP?
Phones can't play Windows Media files, but almost all play 3GP.
What happens when you convert WMV to 3GP?
Fylo re-encodes to H.264 Baseline at up to 720p with AAC audio.
How does Fylo convert WMV to 3GP?
Fylo reads the WMV with ffmpeg compiled to WebAssembly and writes H.264 Baseline profile capped at 720p with 96 kbps AAC audio. WMV's usual codecs (WMV 7/8/9 (VC-1)) can't go into 3GP as-is, so the video is re-encoded. Speed depends on your device: short phone clips take seconds, while on our slow test PC a 2-minute 1080p video took about 10 minutes. Only the first video and audio track are kept, and larger videos are scaled down to 720p (or 480p if you choose it).
What's the difference between WMV and 3GP?
WMV (Windows Media Video) is a family of Microsoft video codecs introduced in 1999, stored in the Advanced Systems Format (ASF) container together with WMA audio. WMV 9 was standardised as VC-1 and used on HD DVD and early Blu-ray discs.
3GP was defined by the 3rd Generation Partnership Project for 3G mobile phones and MMS messaging. It's based on the same ISO media structure as MP4 but restricted to phone-friendly codecs such as H.263 or H.264 Baseline video and AMR or AAC audio.

Frequently asked questions

Short clips usually do, especially at 480p.
Is quality reduced?
Yes, it's optimised for small screens.
