Rule34 Downloader for Windows — Bulk by Tag, Artist or URL

rule34.xxx runs on the older Gelbooru v0.1 engine — the same lineage as Xbooru — and it is one of the highest-volume booru boards around, with images, animated GIFs and WebM clips organized entirely by tag. ArchiveX is a native Windows 10/11 Rule34 downloader that fetches those posts in bulk by tag, artist or a pasted URL and drops every original file into a searchable local gallery, so you are not saving them one right-click at a time.

The catch with rule34.xxx is its API. The public endpoint now generally expects an API key and a user-id before it will return tag results, and the site's heavy tag-alias system means the tag you type may resolve to a different canonical tag on the server. ArchiveX handles the mechanical part: you paste your key and user-id once, type a tag or a combined multi-tag query, and the Rule34 downloader signs each request, pages through the results, skips duplicates, and files everything locally.

To be honest about the alternatives: gallery-dl, Imgbrd-Grabber and yt-dlp are excellent free, open-source tools and they can all pull from Rule34-class sites. ArchiveX is not trying to replace them for people who live in a terminal — it is a no-setup GUI for people who would rather not edit a config file, install Python or wire up a browser extension, and who want the downloaded posts to end up in a library they can re-search offline. Note: rule34.xxx is an adult (18+) site; ArchiveX is for adults archiving public, lawful content only.

🔞 18+ — this covers an adults-only source. ArchiveX is for downloading publicly available content into your own local library; follow each site's terms and applicable laws.

How it compares

FeatureArchiveXTypical alternatives
rule34.xxx API key + user-idPaste your key and user-id once in settings; ArchiveX attaches them to every tag request automatically.gallery-dl and Imgbrd-Grabber also support Rule34 API credentials — they just expect you to add them in a config file or app settings by hand.
Tag aliases & combined multi-tag queriesType multiple tags in one box; the query goes to the API so aliases resolve exactly as rule34.xxx resolves them.gallery-dl and Imgbrd-Grabber pass your tag string straight through too, but you assemble and debug the query yourself.
GIFs and WebM/animated postsSaves the original file whether a post is a JPG, an animated GIF or a WebM clip — all in one pass.yt-dlp targets streaming video, not booru still/GIF galleries; gallery-dl fetches booru originals much like ArchiveX.
Large single-tag pulls (many pages)Walks the API pagination automatically, skips duplicates, and files everything under one tag.gallery-dl paginates well from the command line; a browser or extension leaves you scrolling and saving manually.
Built-in searchable local galleryEvery download lands in a local library you can filter and re-search offline.gallery-dl and Imgbrd-Grabber write files to disk; browsing and searching is left to your file explorer.
SetupInstall the Windows app and go — no Python, no command line, no browser extension.gallery-dl and yt-dlp are command-line tools; Imgbrd-Grabber is a GUI but still needs manual source and credential setup.

FAQ

Do I need a rule34.xxx API key or user-id to use this Rule34 downloader?
For most tag pulls, yes. rule34.xxx's public API now generally requires an API key and a user-id, and unauthenticated searches often come back empty. In ArchiveX you paste both into settings once, and the Rule34 downloader attaches them to every request so your searches aren't rejected. You can find the key and user-id in your rule34.xxx account/API settings.
How does the Rule34 downloader handle tag aliases and combined multi-tag searches?
rule34.xxx is built on the older Gelbooru v0.1 engine and uses a heavy tag-alias system, so a tag you type may resolve to its canonical alias on the server. ArchiveX sends your query straight to that API, so aliases resolve the same way they do on the site. For combined multi-tag searches, enter several tags together and the Rule34 downloader returns only the posts that match all of them.
Can it download GIFs and WebM / animated posts from rule34.xxx?
Yes. rule34.xxx hosts still images, animated GIFs and WebM clips, and the ArchiveX Rule34 downloader saves the original file for each post regardless of type. If a single tag pull mixes stills, GIFs and WebM, they all land in the same local gallery — you don't need a separate tool for the animated posts.
How many posts can a single Rule34 tag pull return?
rule34.xxx is very high-volume, and a popular tag can match tens of thousands of posts. Rather than stopping at the first page, the Rule34 downloader pages through the API automatically — and you set a cap on how many posts to fetch so a broad tag doesn't pull more than you intend. Duplicates found across pages are skipped.
Does the same workflow carry over to Xbooru and other Gelbooru-0.1 boards?
Largely, yes. Because rule34.xxx shares the older Gelbooru v0.1 lineage with boards like Xbooru, the tag-based approach and API-key handling are similar. ArchiveX ships dedicated sources for those boards, so once you're comfortable with the Rule34 downloader you can point the same tag-and-download flow at Xbooru, TBIB and other supported boorus.
Is rule34.xxx content age-restricted, and what should I download?
rule34.xxx is an adult (18+) site, so this Rule34 downloader is intended for adults only. Use it for public posts you have the right to save, for personal and lawful archiving — not to bypass a site's access controls or to infringe an artist's copyright. ArchiveX only automates the fetch-and-organize step; what you choose to download is your responsibility.
