Tumblr Video Downloader
Paste any Tumblr post URL and save the native video as mp4 — including videos buried three reblogs deep.
Why download Tumblr videos with ViralMint?
Tumblr's video player hides the source file behind a JS-rendered embed, and reblogs often point at the original post on a different blog entirely — which is why generic downloaders frequently grab a preview GIF instead of the actual video. ViralMint follows the reblog trail to the source post and downloads the native mp4 at the quality it was uploaded in. Posts on blogs marked as mature require a logged-in session (cookie auth in Settings). For archiving your own blog before a purge or migration, pair it with batch mode on your blog's video page.
How to download from Tumblr
-
Copy the Tumblr video URL
From tumblr.com, copy the share or page URL — e.g.
https://www.tumblr.com/staff/612345678901234567 -
Paste it into ViralMint
Open the ViralMint desktop app and paste the URL into chat. The planner detects the Tumblr URL and triggers the download automatically — no flags, no command line.
-
Get the mp4, transcript and AI insights
The video lands in the Videos page with a local Whisper transcript and AI-extracted hook / structure / tone — ready for clip extraction or repurposing.
Frequently Asked Questions
Can I download a video from a reblog?
Yes — ViralMint resolves the reblog chain to the original post and pulls the native file from the source blog, so you get the real mp4 rather than the compressed preview loop that shows in the dashboard.
Does it work on mature-flagged or hidden blogs?
Blogs behind Tumblr's mature-content wall need a logged-in session: export your browser cookies once via Settings → Cookies and those posts resolve like any other. Deleted posts and blogs are gone — no downloader can recover them.
What about Tumblr GIFs and photo sets?
This tool targets native Tumblr video posts. Animated GIFs are images, not video streams — save those directly from the browser. If a 'GIF' loops with sound, it's actually a video post and downloads normally as mp4.
How ViralMint compares to other Tumblr downloaders
| Approach | Examples | Trade-off | ViralMint advantage |
|---|---|---|---|
| Online converters | Y2mate, SaveFrom, ssyoutube, OnlineVideoConverter | Pop-up ads, redirects, quality capped at 720p, file-size limits, no batch downloads, your URL logged to ad networks | Local app, zero ads, original quality (up to Original upload quality (up to 1080p)), unlimited file size, batch mode |

| yt-dlp command line | yt-dlp, youtube-dl | Most flexible option but requires terminal comfort, manual cookie handling, no GUI for batch selection | Same yt-dlp under the hood, wrapped in a desktop GUI with cookie auto-detect, batch UI, and post-processing pipeline |
| Closed-source desktop apps | 4K Video Downloader, Allavsoft, ByClick Downloader | Closed-source, paid tiers gate batch and HD, no AI pipeline, no extensible Whisper / FFmpeg post-processing | Open source (AGPL-3.0), AI features prepaid per-action, integrates with the rest of the ViralMint creator pipeline |
Supported URL Example
https://www.tumblr.com/staff/612345678901234567Equivalent yt-dlp command
If you already use yt-dlp, the desktop app's Tumblr download is equivalent to running:
yt-dlp -f "bv*+ba/b" --merge-output-format mp4 "https://www.tumblr.com/staff/612345678901234567"ViralMint also auto-runs Whisper transcription, downloads the thumbnail, and extracts AI hook / structure / tone insights — steps that take a separate command chain in raw yt-dlp.
