What is an FLV file?

FLV – Flash video. FLV is Flash Video, the format of the Flash Player era (early YouTube). Few programs make it today. Converting makes a new file: the video is decoded and encoded again, so converting from a format that lost detail never brings it back.

What is an MP3 file?

MP3 – MP3 audio. MP3 is the most widely played audio format: music compressed to about a tenth of its size, which every phone, player and car stereo plays. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Frequently asked questions

Is converting FLV to MP3 free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my FLV files uploaded anywhere?

This conversion runs on our server, because converting video needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.

How large can the FLV file be?

Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.

Will the MP3 look the same as the FLV?

Only the sound is kept: the pictures are left out, and the MP3 is made from the first sound track.

Can I convert several FLV files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
