Do I need to install any software or browser extensions?

No installation is required. Everything runs seamlessly in modern web browsers including Chrome, Safari, Firefox, Edge, and mobile browsers on iOS and Android.

Are there any file size or daily conversion limits?

No. Because the processing is handled entirely by your own device rather than expensive server clusters, there are no artificial daily limits, queues, or paywalls.
