On the front page, click Upload in the top menu. On the upload page, either paste the link to the image, or click the upload box to upload a file from your computer.

The link doesn't have to be a direct image link. For most sites, you should paste a link to the page containing the image, rather than the image itself. For example, for Twitter and Pixiv you can paste a link to the tweet or Pixiv post, rather than a link to the image itself.

When uploading files from your computer, it's possible to upload multiple files at once by selecting them all in the file picker window. It's also possible to upload ZIP or RAR files.

Don't upload content that is poor quality, off-topic, a paid reward, or AI-generated. Refer to the upload rules for more details.

There are a few tools that make uploading much faster and easier:

• Use the bookmarklet or the Upload to Danbooru browser extension to upload images in one click.
• Use the Pixiv Image Searches and Stuff and Translated Pixiv Tags userscripts to check if images have already been uploaded to Danbooru.
• Use the Image Search Options browser extension to check if something has already been uploaded to Danbooru, or to find the original source.

When you first start, you can have up to 15 pending posts in the moderation queue at once. If you hit your upload limit, you have to wait until your uploads are either approved or deleted in three days before you can upload again.

Your upload limit goes up as your uploads are approved, and goes down if your uploads are deleted. When you first start, you need 10 approvals for your upload limit to go up. Every time your limit goes up, you need 2 more approvals to get to the next level. Your limit will go down after every 3 deletions.

See about:upload limits for more details.

All new uploads go through a moderation queue, where they're reviewed by a team of approvers. Posts have three days to be approved. If they're not approved by anyone in three days, then they're deleted.

All it takes is a single approver liking a post for it to be approved. Posts are only deleted if every approver who sees it doesn't think it's good enough to be approved. Most posts are deleted because multiple approvers saw it and none of them thought it met Danbooru's standards.

Usually there are around 10 to 15 active approvers at any given time.

Usually because it didn't meet Danbooru's quality standards. You can ask for feedback in the Upload feedback thread if you're not sure why something was deleted. Keep in mind there often isn't much to say beyond "it wasn't very good".

If you think your post was unfairly deleted, you can appeal it. Go to the deleted post, then click the "Appeal" button in the sidebar. This will put it back in the moderation queue for another three days, where it has another chance to be approved.

Keep in mind that if you appeal something immediately after it was deleted, it will probably be seen by the same people who passed over it the first time. Waiting a few days can improve your odds.

Deleted posts can still be seen by everyone. They're simply filtered out of searches by default. To see deleted posts, add is:deleted to your searches or click the "Deleted" button in the sidebar.

If you want to always see deleted posts, you can go to your account settings and enable the "Show deleted posts" option. This lets you effectively ignore the moderation system.

To add a tag, click the "Edit" button beneath the image and add your tags in the "Tags" box. To remove a tag, simply delete the tag from the Tags box. Click the "Submit" button when you're done.

Anyone can add or remove tags on a post. You don't need any special privileges. All you need is to create an account first.

Tip: you can press "Shift+E" to quickly open the tag edit box in a window, and "Ctrl+Enter" to save the tags when you're done.

Tag the post with character:character_name_here or copyright:copyright_name_here. For example, tagging a post with character:hatsune_miku or copyright:vocaloid would create the Hatsune Miku or Vocaloid tags (if they didn't already exist).

First tag the post with artist:artist_name_here. After you add the tag, a message will appear saying that you need to create a new artist entry. Click the "Create new artist entry" button, then add all the artist's profile pages to the URLs section, then click "Submit".

Go to the Artist alias request thread, click Request alias/implication at the top of the page, then write alias old_artist_name -> new_artist_name in the "Request" box. Give a reason in the "Reason" box.

If you can't figure it out, just post in the thread and another user will help you.

A bulk update request (a BUR for short) is a forum request to change a tag or group of tags. It's a called a bulk update request because it's a request to update one or more tags in bulk.

To make a bulk update request, go to the forum, click Request alias/implication at the top of the page, then write your request in the "Request" box. Give a reason for the request in the "Reason" box.

This will create a new forum thread where other users can discuss and vote on your request. An admin must approve your request for it to go through. Look at other threads to get a feel for how to write your request.

An alias is an alternate name for a tag. For example, yellow hair is aliased to blonde hair because yellow hair is the same thing as blonde hair. Searching for yellow hair will automatically redirect you to blonde hair. Tagging a post with yellow hair will automatically add blonde hair instead.

An alias is used when two tags mean the same thing, or when there are multiple words people might use for the same concept.

An implication is when one tag automatically adds another tag. For example, the white shirt tag implies shirt because a white shirt is a type of shirt. Tagging a post with white shirt will automatically add the shirt tag too.

An implication is used when adding one tag should always add another.

Go to the forum, click Request alias/implication at the top of the page, then write alias old_tag_name -> new_tag_name in the "Request" box. Give a reason for the request in the "Reason" box.

This will create a new forum thread where other users can discuss and vote on your request. An admin must approve your request for it to go through. Look at other threads to get a feel for how to write your request.

A deprecated tag is a tag that can't be added to new posts. Tags are deprecated when it's decided they should no longer be used, usually because they're too ambiguous, or there are other better tags available.

For example, case is deprecated because it could mean a suitcase, a guitar case, a CD case, or some other type of case. The case tag is deprecated to prevent people from still using it.

A tag qualifier is a word in parentheses at the end of the tag, to disambiguate it from other tags with the same name. For example, in arrow (projectile) the qualifier is "projectile", to distinguish it from arrow (symbol).

A copyright tag is a tag for a game, anime, manga, book, movie, or any other kind of fictional universe or property. In general, copyright tags are for things with characters. They're called copyright tags for lack of a better name. Copyright tags are colored purple.

Copyright tags aren't for brand names, company names, trademarks, or other things without characters.
