Universal Bluesky Carousel & Slideshow Downloader (ZIP & MP3 Extraction)
Bluesky posts support up to four images attached via the embed.images[] array in the AT Protocol record. Instabatch resolves each blob reference, fetches the full-resolution image from Bluesky's CDN, and delivers them without compression or watermarks.
Preview all Bluesky post images in our gallery viewer, download individual photos, or save the complete multi-image set as a Zero-Compression ZIP. Decoupled Auth means your Bluesky handle and app password are never needed.

Instabatch
How do I download all images from a Bluesky multi-image post as a ZIP?
Copy the bsky.app post URL, paste it above, and click download. We parse the embed.images[] array from the AT Protocol record, fetch each blob from Bluesky's CDN, and package them into a Zero-Compression ZIP.
How does Instabatch resolve Bluesky embed.images[] via Decoupled Auth?
Our server fetches the post record from the Bluesky API, extracts blob CID references from embed.images[], resolves each to a CDN URL, and streams the raw bytes — your Bluesky credentials are never involved.
Will Bluesky notify the poster when I download their multi-image post?
No. Server-side CDN blob extraction does not register as an in-app save or repost action. The fetch occurs on our infrastructure outside the Bluesky client.
What resolution are Bluesky image downloads?
We fetch the full blob referenced in embed.images[] — the same resolution uploaded by the poster. Aspect ratios are preserved with zero recompression via our Magic Byte verified pipeline.
Can I download individual images from a Bluesky post with multiple photos?
Yes. Our gallery viewer displays each embed.images[] entry as a swipeable slide. Download specific images or use Download ALL (ZIP) for the complete set.
What does the Magic Byte sniffer detect for Bluesky blob downloads?
After fetching each blob, our server inspects the header for JPEG (\xff\xd8\xff), PNG (\x89PNG), or WEBP magic bytes — assigning the correct extension and confirming the raw upload quality is preserved.
