Frequently asked questions
Can modern phones play 3GP files?
No — modern iOS and Android don't natively support 3GP. VLC for iPhone or Android plays 3GP. The most practical approach: convert 3GP to MP4 once, and the files play natively everywhere.
What quality can I expect from old 3GP videos?
3GP videos from feature phones were typically 176×144 or 352×288 at 10-15 fps with very low bitrates. Converting to MP4 doesn't improve the resolution — it makes the existing low-res video accessible on modern devices.
