Every time someone needed to convert an MP3, trim a voice note, or add reverb to a track, they had to choose between uploading their private recordings to a random server,
installing bloated desktop software, or paying for a subscription to use one feature once.
We thought that was unnecessary. Modern browsers are powerful enough to handle all of it locally — no uploads, no installs, no accounts. So we built AudioCharger: every audio tool
you actually use, running entirely in your browser, completely free.

What feedback would help us most
We're early and actively improving. The most useful thing you can tell us:
- Which tool did you come for? Knowing which tools people actually use helps us prioritise what to build next.
- Did it work on your file? Edge cases — unusual formats, large files, recordings from specific devices — are hard to test in advance. If something broke, we want to know.
- What's missing? Is there an audio task you do regularly that we don't have yet?
- How was the speed? Especially on mobile or older hardware — processing happens on your device, so performance varies.
