Free Music Lab

Frequently asked questions

Audio & video editor

+Is the editor really free?

Yes. There is no sign-up, no watermark and no export limit. The site is paid for by the ads you see around the page.

+Are my files uploaded to a server?

No. Everything happens inside your browser on your own phone or computer. Your video and audio never leave your device, so the editor also works with private recordings.

+Which file formats can I open?

Anything your browser can play: usually MP4, MOV (on Safari), WebM, MP3, WAV, M4A/AAC, OGG and FLAC. If a file won't open, try converting it to MP4 or WAV first or use another browser.

+Can I extract the audio from a video?

Yes. Open the video, trim it if you want, then choose Export → Audio only. You get a WAV file with your EQ, volume and fades applied.

+Why does video export take as long as the clip?

Video is recorded while it plays through once in real time, so a 2-minute clip takes about 2 minutes. Audio-only export is rendered instantly.

+Do I get MP4 or WebM?

It depends on your browser. Recent Chrome, Edge and Safari versions export MP4; others export WebM. Both play in most players and upload fine to social networks.

+What is a dynamic EQ band?

A normal EQ band always boosts or cuts. A dynamic band only acts when that frequency gets louder than the threshold, for example taming harsh 's' sounds or a boomy bass note without dulling the whole track.

+Does it work on mobile?

Yes, the editor is designed for phones first. You can also add it to your home screen from the browser menu and use it like an app.

Video to MP3 converter

+Is this video to MP3 converter free?

Yes, completely. No account, no watermark, no daily limit. The site is funded by the ads around the page.

+Is my video uploaded anywhere?

No. The audio is extracted and encoded inside your browser, on your own device. Only the small MP3 encoder is downloaded from the internet; your file never leaves your phone or computer.

+Which video formats work?

Anything your browser can play: MP4, MOV (best on Safari), WebM and usually MKV, plus audio files like WAV, M4A, OGG or FLAC. If a file doesn't work, try Chrome or Edge.

+Which quality should I choose?

192 kbps sounds great for music and is a good balance. 320 kbps is the highest MP3 quality. 128 kbps or mono is enough for voice, lectures and podcasts and makes much smaller files.

+Can I convert YouTube or Instagram links?

No. The converter only works with files you already have on your device, such as videos you recorded or own. Downloading from streaming sites usually breaks their terms and copyright.

+Can I cut the audio or improve the sound first?

Yes: open the video in the free audio & video editor, trim it, fix the sound with the EQ and export it as audio. Then convert the result here if you need MP3.

About the site

+Who makes this site?

Álvaro Soto, an independent Spanish musician and audio producer based in Galway, Ireland. The tools are built to be the ones I wanted when practising, teaching and mixing.

+Why are there ads?

Ads pay for hosting and development so every tool can stay free without accounts or paywalls. They are kept away from the editing controls.

+Can I order a transcription or arrangement?

Yes. Use the contact page to send a WhatsApp message or an email with the song, instrumentation and deadline, and you'll get a quote.

+Is the site available in other languages?

Every page is available in English and Spanish. Use the language switch at the top of the page.
