Frequently asked questions

Is there a file size limit?

There is no fixed limit, but browsers cap memory. Files up to a few hundred megabytes usually work on a computer, while phones prefer smaller clips.

Will the MP3 sound as good as the video?

MP3 is lossy, but at the quality used here most people cannot hear the difference from the original soundtrack.

Can I get WAV or M4A instead?

Convert to MP3 here, or use the Audio tab to change the audio into WAV, M4A, OGG or FLAC.
