Frequently asked questions
Will the quality improve?
No: the original resolution and quality (often 176×144) are preserved as-is; converting doesn't invent detail.
Which 3GP codecs are supported?
H.263, MPEG-4 SP and AMR — the usual ones from that era.
Is AMR audio converted?
Yes, to standard AAC.
Can I upscale the video afterwards?
You can resize it, but upscaling interpolates: it won't recover lost detail.
