Features & Capabilities

Substack Video Downloader lets you save Substack videos, audio posts, and podcast episodes directly to your device as MP4 or MP3 files. Download embedded Mux videos in quality up to 1080p with Pro, or save audio from native Substack players for offline listening.

The Firefox add-on automatically detects media, including dynamically loaded and hidden players, across Substack publications and custom domains. Use the player download button for quick saves or open the extension popup to review detected media and download multiple files at once. Optional Google Drive and Dropbox integration supports cloud backup, while file naming and folder organization help manage large collections.

The extension runs locally in your browser without ads, tracking, analytics, or required external services. Download only content you have permission to access and save.
