3GP

3GP is a multimedia container format defined by the 3rd Generation Partnership Project (3GPP) for use on 3G mobile phones. It is a simplified version of MP4 designed for low bandwidth and limited storage, storing video (H.263/H.264) and audio (AMR/AAC) streams optimized for mobile playback.

Frequently Asked Questions

Is converting 3GP to FLV free?
Yes. This 3GP → FLV converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert 3GP to FLV?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my 3GP files uploaded to a server?
No. Files never leave your device. The entire 3GP → FLV conversion runs locally in your browser, so your data stays private.
Can I convert multiple 3GP files at once?
Yes — batch conversion is supported. Add as many 3GP files as you like and convert them to FLV in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting 3GP to FLV reduce the quality?
Because both formats use lossy compression, the FLV output will not bring back any quality that has already been lost in your 3GP file. Avoid repeated re-encoding to keep the best quality.
Does FLV support transparency?
No — FLV has no alpha channel. Transparent areas of your 3GP file will be filled with a solid background colour in the converted file.
How will the file size change after converting 3GP to FLV?
Both formats use comparable compression, so the FLV output will be similar in size to your 3GP file — typically within 10–20% of each other.
