Does pitch change with speed? ▼

Yes — pitch shifts proportionally. This is a simple speed change, not time-stretch.

Is there a file size limit? ▼

No strict limit. Processing happens in your browser, so capacity depends on your device memory. Most files work smoothly.

Which browsers are supported? ▼

All modern browsers including Chrome, Firefox, Safari, Edge, and Opera on both desktop and mobile.

Can I use this offline? ▼

Yes. Once the page is loaded, the tool works without an internet connection since all processing is local.
