Look, we’ve all been there. You find a creator on Kemono.party (or the newer Kemono.su mirror) and they have literally thousands of posts. Clicking "save as" on every single image or attachment is a fast track to carpal tunnel. It's tedious. It's frustrating. Honestly, it's just not how anyone should spend a Saturday night. If you're trying to figure out how to download kemono content all at once, you’re likely looking for a way to archive your favorite art or game assets before a link goes dead or a server crawls to a halt.
The site itself is basically a public archive of paywalled content from platforms like Patreon, Fanbox, and SubscribeStar. Because of how the site is structured—scraped data, messy tags, and often unstable servers—standard browser extensions usually choke on it. You need something more robust than a right-click.
Why Bulk Downloading Is Such a Pain
Kemono isn't a normal gallery site. It’s a mirror of many different platforms. This means the file structures are all over the place. One post might have a single .zip file, while another has fifty high-res JPEGs and a stray .txt file. When you try to download kemono content all at once, most "bulk image downloader" extensions just see the thumbnails. They miss the full-resolution files hidden behind the links.
It gets worse. The site uses specific rate-limiting to prevent DDoS attacks. If you slam their servers with too many requests at once, your IP gets a temporary timeout. You've probably seen that "502 Bad Gateway" or "429 Too Many Requests" screen. It’s the bane of every digital hoarder's existence. You need a tool that respects the server's limits while still doing the heavy lifting for you.
The Go-To Solution: Gallery-dl
If you ask anyone who spends way too much time archiving web content, they’ll point you to gallery-dl. It’s a command-line program. I know, "command line" sounds scary if you aren't a coder, but it’s actually pretty straightforward once you get the hang of it. It’s open-source, it’s updated constantly, and it handles Kemono's weird quirks better than anything else out there.
Basically, gallery-dl acts like a super-powered browser that knows exactly where the "real" image links are hiding. Instead of you clicking every post, the script reads the creator’s page, identifies every attachment, and pulls them down into neat folders on your hard drive.

To use it, you generally need Python installed. Once you have that, you just run a simple command like gallery-dl "URL_OF_CREATOR". But wait. Don't just run it blindly. You'll want to configure it. If you don't, it might dump 5,000 images into one folder called "images," which is a nightmare to sort through later. You can set up a configuration file (usually a .conf or gallery-dl.conf) to tell the program to sort files by creator name, post date, or even post ID.
Dealing with the "403 Forbidden" Error
This is the big one. Kemono often changes its domain or adds new protections. If you're using an outdated version of any downloader, you'll get hit with 403 errors. This means the server knows you're a bot and is blocking you.
The fix? Keep your tools updated. For gallery-dl, that’s just running pip install -U gallery-dl.
Another trick involves cookies. Sometimes, the site requires you to "prove" you've visited the page recently. You can export your browser cookies into a cookies.txt file and tell your downloader to use them. This mimics a real human browsing the site, which often bypasses the more aggressive bot-detection layers. It’s a bit of a cat-and-mouse game, honestly.
The User-Friendly Alternative: RipMe
Not everyone wants to look at a black box with scrolling white text. I get it. If you want a GUI (Graphical User Interface), RipMe is the old-school favorite. It’s a Java-based app. You paste the link, hit "Rip," and watch the progress bar.
However, a word of caution: RipMe isn't always as fast to update as gallery-dl. Because Kemono changes its layout frequently to handle high traffic, RipMe "albums" can break. If you find that it’s only downloading the first page or skipping files, it’s probably because the "ripper" script for Kemono needs an update. Always check the GitHub releases page for the latest version. If it’s been six months since the last update, it might not work for the current version of the site.
Specialized Browser Extensions
Maybe you don't want to install standalone software. There are a few browser extensions that claim to download kemono content all at once, like "Download All Images" or "Bulk Image Downloader."
They are... okay. Sorta.
The problem is they often grab everything on the page—icons, ads, UI elements, and those tiny thumbnails. You end up with a folder full of 200x200 pixel garbage. To make these work, you usually have to scroll to the very bottom of the creator's page to make sure every post has "loaded" into the browser's memory. On a page with 400 posts, that’s a lot of scrolling. And even then, they might miss the "original" files that are only accessible by clicking into the individual post.
The Ethics and Safety of Mass Downloading
We have to talk about the elephant in the room. Kemono is a "leaks" site. While the tech for downloading is interesting, remember that the content belongs to creators who often rely on that income. If you're archiving stuff you already paid for but want a local backup (because Patreon’s interface is objectively terrible for browsing old art), that’s one thing. If you’re just vacuuming up someone’s entire career for free, maybe consider tossing them a few bucks if you like their work.
Also, be careful about what you run on your machine. Never download a "Kemono Downloader.exe" from a random forum or a shady YouTube link. Those are almost always malware or at least bundled with nasty adware. Stick to reputable open-source tools on GitHub where the code is public and audited by the community.
Organizing Your Archive
Once you successfully download kemono content all at once, you’re going to have a mess. Even with good folder structures, five gigabytes of art is hard to navigate.

I highly recommend using a local image organizer. Something like Eagle.cool or even a simple file renamer. If your downloader didn't name files by date, you can use tools like Bulk Rename Utility to add timestamps. This makes it way easier to see the progression of a creator's style over the years.
Troubleshooting Common Issues
Is it stuck?
If your download stops at 10% and just sits there, you’ve likely been rate-limited. The best thing to do is wait. Don't restart the script immediately—that just tells the server to block you for longer. Give it an hour.
If you're using gallery-dl, you can actually set a "sleep" timer between downloads. Adding a --sleep 2 flag tells the program to wait two seconds between every file. It takes longer, but it’s much more likely to finish without getting your IP banned. It’s the "slow and steady wins the race" approach.

Key Steps to Get Started Now
- Check your storage. High-res art and animation files are huge. Make sure you aren't about to fill up your C: drive.
- Pick your tool. Go with
gallery-dlif you can handle a tiny bit of technical setup. Go withRipMeif you want a button to click. - Update everything. An outdated downloader is a broken downloader.
- Test a small creator first. Don't try to download a creator with 10,000 posts as your first test. Find someone with 10 posts. See if the files end up where you want them and if the quality is right.
- Use a VPN if necessary. If your ISP blocks the site or if you're getting constant 403 errors, a VPN can sometimes help, though some VPN IPs are also flagged by the site’s protection layers.
The reality is that sites like Kemono are inherently unstable. They move domains. They go down for maintenance. The "all at once" method is the only way to ensure you have a permanent copy of what you're looking for before it disappears into the ether of the internet. Just be smart about it, don't overwhelm the servers, and keep your software updated to the latest version.
Moving forward, focus on setting up a configuration file for your chosen downloader so you don't have to manually sort files every time. This saves hours of manual labor and keeps your digital library clean from the start.
