How to convert 3GP to FLV
Add your 3GP videos
Drop 3GP files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
FLV is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Download
Save the FLV, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The 3GP to FLV converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
3GP to FLV: what to expect
3GP video is low resolution and does not open in many desktop apps. FLV is still used by some live-streaming and recording tools. 3GP is at home in video from older mobile phones; FLV is the usual choice for nothing new; it survives in old downloads and stream recordings.
The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
This pair uses the compatibility engine, ffmpeg built for the browser, because FLV cannot be written by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.
3GP vs FLV
FLV
Flash video
FLV was the format behind web video in the Flash era. Flash Player was retired at the end of 2020, so FLV files no longer play in any browser.
Opens in VLC and little else since Flash Player was retired in 2020

Questions
Are my videos uploaded anywhere?
No. The 3GP to FLV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting 3GP to FLV reduce quality?
It depends on what is inside the 3GP. When its video and audio are already in a form FLV can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.
Can I convert several 3GP files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert 3GP to FLV on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the 3GP file, press Convert and save the FLV. There is nothing to install.
Is there a file size limit?
Yes. 3GP to FLV runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
