Maximum file size you can upload

With Castos Podcast Hosting there are no limits on the number of podcasts or podcast episodes you can create, but there is a generous limit on the size of the file uploaded when uploading audio and video files to your Castos account through WordPress. There are no restrictions on file uploads for Castos only accounts.

Please Note: When working with Castos and WordPress, your files are stored on the Castos servers, but they first pass-through your WordPress site. Be sure your Maximum File Upload Limit for your WordPress media library is set accordingly.

Upload Limits for Castos WordPress Users

The max file size you can upload to Castos through WordPress is 250MB. For your audio podcast, this is the best combination of audio quality, file size, and file format for both your listeners and their podcasting apps.

Following our best practices guide for audio encoding you can upload podcast episodes up to ~ 4 hours in duration. These files are roughly 1 MB per audio minute. If you already have a media file that has been sent to you as a WAV file or another large format file by an audio editor you can compress it to a smaller file size using a tool like https://online-audio-converter.com/

For Seriously Simple Plugin Users

If you are self-hosting your podcast files on your WordPress site, you will have upload limits to the Media Library. This setting can range from 12mb to 300mb and is set by your host. You may need to change that upload limit with your host or through a third-party plugin.
