You have a folder of FLV clips saved from the web, and your phone only plays 3GP. Renaming the files doesn't work, and most general converters bury the one setting you need. ImTOO FLV to 3GP Converter does one job: it turns FLV video into 3GP or 3G2 files that older mobile phones can play.

Quick facts
- Input: FLV video
- Output: 3GP and 3G2 video, plus BMP, JPG, GIF and PNG snapshots
- Platform: Windows 11, 10, 8, 7, Vista and XP (SP2 or later)
- Support: free technical support by email
- Guarantee: a 30-day money-back badge appears on the product page
Key features
Get 3GP and 3G2 files that play on Nokia, Motorola, Samsung and Sony Ericsson phones
The output is aimed at 3GP mobile phones. Profile settings are sorted into types, so you can find the right target without searching through one long list.
Convert a pile of FLV files in one go
Batch conversion lets you queue several FLV files and convert them together. The program also supports multi-core CPUs to speed up the work.
Cut out just the clip you want
You can pick a favorite segment of an FLV video and convert only that. You can also split a file into several clips by time or by file size.
Control bit rate, frame rate, sample rate, codec and resolution
The advanced output settings let you tune the result. A Bitrate Calculator works out the video bit rate from the output file size you want. Add Profiles lets you produce more than one output file from a single FLV source.
Grab still images while you preview
The built-in player is resizable and switches between 4:3 and 16:9. You can capture frames and save them as JPG, PNG, GIF or BMP.
Leave it running and walk away
Conversion runs in the background, so you can use other programs meanwhile. After it finishes, the program can shut down the computer, exit, or put it on standby or hibernate.
Who it's for
It suits you if you have FLV files and a 3GP-only phone or player, and you want a narrow tool with a short learning curve. If you need many input formats or modern phone and tablet targets, a general video converter fits better.
