Yes. Bitrate is the exact factor that defines compressed audio file size. A 128kbps file takes up roughly half the storage size of a 256kbps file, because it stores half the data per second.
For spoken podcasts or audiobooks, 64kbps or 96kbps Mono is extremely efficient and perfectly legible. For music, 128kbps stereo is traditionally standard, while 192kbps and upwards is considered high fidelity.
Picxor can handle files up to 100MB. Very large files may take longer as processing happens in your browser. For files over 50MB, closing other browser tabs helps.
