What file types are downloaded?

- Images (JPG, PNG, GIF, WEBP, etc.)
- Videos (MP4, WEBM, etc.)
- Other attachments
How do I know if downloads are complete?

All files downloaded.Last updated timestamp saved: Saturday, December 7, 2024, 3:45:32 PM ESTCheck the lastupdated.txt file in your download folder to see when you last ran the scraper.
Can I compress the downloaded files?
Section titled “Can I compress the downloaded files?”Yes! After downloading, you can use the built-in compression script:
bun run compressThis converts:
- JPG/JPEG → JPEG XL (30-50% smaller)
- MP4/MKV → AV1 (30-50% smaller)
See the Compression guide for detailed instructions and requirements.
Troubleshooting
Section titled “Troubleshooting”Why do some downloads fail?
Section titled “Why do some downloads fail?”Downloads can fail for several reasons:
- Rate limiting - Too many requests, try again later
- File unavailable - The file was removed from the server
- Connection issues - Network problems, try again
The scraper automatically retries failed downloads. Files that consistently fail are added to a “blacklist” and skipped.
What is the blacklist?
Section titled “What is the blacklist?”When a file fails to download 5 times, it’s added to blacklist.json in your download folder. This prevents the scraper from wasting time on files that don’t exist.
The blacklist automatically expires after 2 days, so files will be retried eventually.
Why is downloading slow?
Section titled “Why is downloading slow?”The sites have rate limits to prevent abuse. The scraper automatically:
- Pauses between requests
- Limits concurrent downloads
- Waits when rate limited
This is normal and helps prevent your IP from being blocked.
”No posts found” error
Section titled “”No posts found” error”This usually means:
- The service or user ID is wrong
- The creator doesn’t exist on Kemono/Coomer
- You’re using the wrong host (e.g., using kemono.cr for OnlyFans)
Double-check your command and try again.
