Universal Tumblr Carousel & Slideshow Downloader (ZIP & MP3 Extraction)
Tumblr's Neue Post Format (NPF) structures multi-image posts as an ordered array of image blocks within the content JSON. Instabatch walks every NPF image block, resolves the 64.media.tumblr.com CDN URLs, and delivers each photo at source resolution.
Preview all NPF image blocks in our gallery viewer, download individual photos, or save the complete Tumblr post as a Zero-Compression ZIP. Decoupled Auth keeps your Tumblr account out of the download flow entirely.
1. Find the NPF Post
Open the Tumblr multi-image post and copy the tumblr.com/blogname/post-id URL from your browser.
2. Paste the Link
Drop the Tumblr post URL into the input above. Our engine parses the NPF content blocks server-side.
3. Download All Images
Browse every image block in the gallery and download individually or as a ZIP.

How do I download all images from a Tumblr NPF multi-image post as a ZIP?
Copy the tumblr.com post URL, paste it above, and click download. We parse the NPF content array, extract every image block's CDN URL, fetch from 64.media.tumblr.com, and package into a Zero-Compression ZIP.
What is Tumblr NPF and how does Instabatch parse it?
Neue Post Format (NPF) is Tumblr's JSON-based post structure. Our engine reads the content[].type=='image' blocks, resolves media URLs from the attrs payload, and fetches each via Decoupled Auth without requiring your Tumblr credentials.
Will Tumblr notify the blogger when I download their multi-image post?
No. Server-side CDN extraction from 64.media.tumblr.com does not trigger Tumblr's reblog or like notifications. The download happens on our server, not through the Tumblr app or website.
What resolution are Tumblr NPF image downloads?
We fetch the largest available CDN variant for each NPF image block — typically the '1280' or raw upload tier. Original aspect ratios are preserved without recompression.
Can I download individual images from a Tumblr photo set post?
Yes. Our gallery viewer displays each NPF image block as a swipeable slide. Download specific blocks individually or use Download ALL (ZIP) for the complete post.
How does the Magic Byte sniffer work for Tumblr CDN downloads?
After each 64.media.tumblr.com fetch, our server inspects the file header for JPEG, PNG, GIF (GIF8), or WEBP signatures — ensuring correct extension assignment and confirming raw source quality.
