- About JustForFans
JustForFans content is not limited to one simple file type. Videos can rely on protected playback, galleries require expansion, and text posts live alongside media in the same feed. Generic downloaders usually ignore half that structure. They miss gallery images, skip feed text, or fail once the video is delivered through a protected player.
JustForFans Downloader is built for the actual feed workflow. It scans visible posts, groups content by type, and gives you direct save options for videos, images, galleries, and text from the same page.

- Per-post download controls for targeted saves
- Bulk "Download Visible" action for on-screen feed content
- Converts HLS streams and DASH encrypted video to MP4 in-browser

- Copy playlist URL with headers to use in tools
- None documented; rely on page and player data extraction
# No public API calls identified; extract URLs from HTML/player data
- Use authenticated endpoints only; no public API documented
- Find HLS playlist URL from network requests
- Fallback to MP4 URL if present
- Require user login for any download action
- Refresh URLs if they expire
- Include creator name and post ID in filename
- Signed URLs expire quickly; avoid long delays
JustForFans uses signed HLS playlists behind authentication. Download implementations should rely on user sessions, capture fresh playlist URLs, and use yt-dlp or ffmpeg to produce MP4 outputs.
| Tool | Best Use Case | Notes |
|---|---|---|
| yt-dlp | Primary downloader for MP4/HLS | Supports cookies, format selection, retries |
| ffmpeg | Remuxing and validation | Useful for HLS to MP4 conversion |
| streamlink | Live/HLS fallback | Streams to file or pipes into ffmpeg |
| aria2c | Multi-connection HTTP/HLS downloads | Good for large files and retries |
| gallery-dl | Image-first or gallery-heavy sites | Best for gallery or attachment extraction |
