Common questions about how 123tools works
Do I need to install any software to convert files?
No. Everything runs in your browser. Drag a file in, pick your settings and go.
What formats are supported?
MP4, MP3, MOV, AVI, WebM, FLAC, M4A, MKV, WMA, GIF and more. If it's a common video or audio format, we probably support it.
Can I extract audio only from a video file?
Yes. Upload a video and pick an audio format like MP3 or WAV. We extract just the sound.
How long does the conversion take?
Small files finish in seconds. Larger ones take a couple of minutes. Processing happens on our servers, so your device speed doesn't matter much.
Is it safe to use this service?
We don't keep your files. They're processed, you download the result, and they're deleted from our servers. All transfers use HTTPS.
