Audio
You can upload three common audio file types, .wav, .mp3, and .flac.
Please note that most browsers do not support 32 bit .wav files, so playback will be distorted for your clients, even though Filepass itself can technically support 32 bit files.
Due to this, it is highly recommended that you only upload 16 and 24 bit .wav files.
Images
Images are also supported, in the formats .png, .jpg, and .pdf
Archives
You can also upload .zip archives, which can come in handy:
To speed up uploads/downloads
To prevent clients from listening to your files until they are fully paid for (.zip files won't be streamable)
To upload files that aren't audio or images
