4chan is an online community forum where users can post images and text anonymously under many topic boards like animation, culture, videogames, music, and photography. Launched in 2003, it’s best known for its loose moderation, fast activity threads, and you don’t even need an account to post anything.
Although the platform’s interface is minimal, you may find it hard to post on 4chan. It’s not that difficult, and this guide will show you how to do this quickly.
5 Steps to Post on 4chan
You can post on 4chan by following these 7 easy steps:
Step 1. Access 4chan Boards
First, open a browser of your choice and then go to the 4chan website. On the home page, pick a board that matches what you want to post—it’s listed under the “Boards” section.

If you just want to see what is trending, scroll down and check out “Popular Threads” for the hottest discussions.

Step 2. Start New Thread to Post
Under the board’s name, you’ll see the “Start a New Thread.”

Simply click on it, and a new pop-up box will open.

Step 3. Fill Your Thread Details
The next step is to fill in what you want to post. You can leave the “Name” and “Options” fields because they are not mandatory. Type in the subject of your post and the complete comment you want 4chan to show on the thread.

Now, fill in the CAPTCHA by clicking “Get CAPTCHA.” As soon as you click it, a timer will start and show you the CAPTCHA that you need to enter in the “TYPE THE CAPTCHA HERE” field.

Step 4. Skip the CAPTCHA
The timing for the CAPTCHA generation may take 4-6 minutes. If you don’t want to wait that long, you can buy a 4chan Pass.
A 4chan Pass lets you skip the CAPTCHA every time you post or report something on the boards. It was a community-suggested idea, meant to make things smoother while supporting the site. The cost is $30 for a year or $60 for three years, which breaks down to about $1.67 a month.

You just have to provide your email, choose the $30 or $60 plan, and complete the checkout process with your credit card. If you don’t have one, you can also pay with Crypto like Bitcoin, Ethereum, and digital currencies.
Step 5. Post Your Thread
Lastly, upload an image to share with your newly created thread, and then click “Post.”

Your post will now show as active on that specific board. If someone replies to your post, it moves back to the top of the board. But once a post expires, it’s gone for good—you can’t get it back. Since the site moves fast, most posts disappear within a few hours or days.
Rules for Posting on 4chan
4chan moderation is not that strict, but there are still some rules you need to follow:
- Don’t post, share, request, or link to anything that breaks U.S. or local laws.
- If you’re under 18, you must leave the site right away and not come back.
- Obvious bait or trolling, discriminatory or hateful content, adult-themed furry material, violent or disturbing imagery, content depicting underage characters in explicit settings, and posts like “Roll for X” or anything related to number games are not allowed outside of the /b/board
- Don’t share or ask for personal information (doxxing), and don’t organize or take part in group spam or raids. Starting fights between boards is also against the rules.
- Boards using the Yotsuba B (blue) theme are considered safe for work. NSFW content, even when hidden with spoilers, is not allowed and can lead to temporary bans.
- Post quality matters. Aim to share meaningful images and thoughtful comments. Avoid meme spam or repeated catchphrases, text that doesn’t make sense or is impossible to read, large ASCII art blocks, intentional low-effort or nonsense posts (aka “shitposting”).
- Don’t misuse the report feature. Submitting fake reports or mentioning that you’ve reported a post can get you banned.
- Complaining about the site’s rules or moderation on the boards can lead to post removal or a ban.
- Trying to dodge a ban will only get you banned permanently. Wait it out or file an appeal.
- No spamming, flooding, or trying to sneak around post filters.
- Advertising of any kind is not allowed. That includes referral links, shoutouts, begging, promo threads, or anything similar.
- Don’t pretend to be a site admin, moderator, or janitor.
- Avatars and signatures aren’t allowed in posts.
- Don’t use scripts, bots, or automated tools to post or download. Posting from proxies, VPNs, or Tor nodes is also banned.
- Content related to ponies or the brony fandom should stay on /mlp/.
- If you’re making adult content requests, post them on /r/. For safe-for-work requests, use /wsr/, unless told otherwise.
- Images that contain hidden files, like sounds or documents, are not allowed.
Concluson
In this guide, you’ve learn all about how to post on 4chan, which is pretty simple. But it comes with a set of rules. Pick the right board, follow the guidelines, and avoid low-effort posts. You don’t need an account—just share your thoughts or images and join the conversation.
Keep in mind that posts disappear fast, so nothing stays forever. If you want to skip CAPTCHAs, consider buying a 4chan yearly Pass. Like any other platform, the important thing here is to respect the community standards and not post anything that could get you banned.
FAQs
What is the B rule on 4chan?
The /b/ board is known for having the loosest rules on 4chan, but that doesn’t mean anything goes. Illegal content is still banned. It’s the spot for random posts, but even there, some limits still apply—like keeping certain topics off other boards and avoiding spam or doxxing.
Do I need a VPN to post on 4chan?
No, you don’t need a VPN to post on 4chan, but some users use one for privacy. However, 4chan often blocks VPNs and proxies, so posting through them might not work. You’re better off posting normally unless you have a specific reason to hide your IP.
How do I get more comments on a post?
On 4chan, replies mostly depend on timing and content. Try to post during peak hours, use an eye-catching image or a bold opinion, and keep it short. It’s also best to avoid being vague because threads that spark reactions or debates usually get bumped more and stay visible longer. Just don’t force it or bait too hard.
