Images

Audio

Images can only convert to images, audio only to audio. Converting across types (like a PNG to WAV) isn't something a file format supports — the pixel data and sound wave data are fundamentally different, so there's no meaningful way to turn one into the other. Trying it in the queue will show you why.

Enable rate limit Caps how many conversions you can run per time window — purely optional, doesn't make anything more efficient or "safe." It's here in case you want a self-imposed limit.
Every conversion happens in your browser using its built-in media APIs. Nothing is uploaded, logged, or stored on a server — closing this tab clears everything except your saved preferences.
