1. Comic Entries
    1. Only manga, manhwa, manhua, or doujinshi and webcomics of the aforementioned categories are allowed. Exceptions can be made, but contact staff beforehand.
    2. Oneshots that were published in an anthology should be included in the respective anthology entry and should not have their own entries.
    3. A single-chapter oneshot that has been serialized should be included in its respective serialized entry.
    4. A self-published comic with multiple chapters that has been serialized should have its own separate entry. If the serialized comic uses the same title, the pre-serialized entry should have "(Webcomic)" or the equivalent appended to the title.
    5. The previous rule aside, entries should not have "(Oneshot)" or anything similar appended to the title. Use the appropriate tags instead.
    6. Do not add duplicate entries. Search for multiple alternate titles before adding a series.
    7. If there are multiple entries with the same title, do not add anything to distinguish them. Use the actual title as it is.
    8. Cover Image
      1. Format: file type JPG or PNG, portrait orientation, minimum aspect ratio 1:1.15, preferable minimum resolution 300px * 450px, maximum file size 1MB.
      2. Content: Use a cover image of a later volume, unless it either doesn't fit the overall art style or theme of the comic or has major spoilers.
    9. Tag porn (and only porn) as hentai. Ecchi and smut do not count. The primary focus must be on the sex, and genitals must be visible (typical censorship aside).
      1. Oversimplified rule of thumb: if it's mostly porn with some plot, it's probably hentai; if it's mostly plot with some porn, it's probably not.
  2. Upload Restrictions
    1. Scans of official releases or webcomics from official sources, such as original releases (raws) or officially translated releases, are not allowed to be uploaded.
      1. The only exception to this rule is for officially translated releases where either the license is expired, the series is out of print, or the publisher is defunct and that release can no longer be purchased through the publisher. These releases will be uploaded under the group "[Publisher] (Ex-Licenses)", and are treated as scanlations for the purpose of all rules.
        1. However, if unofficial scanlations of the respective chapters are available, do not upload the official versions unless there is a significant difference in quality. Contact staff in case of doubt.
        2. If another publisher has made their own official release afterwards, the expired/defunct version may still be uploaded.
    2. The existence of an official translation has no relevance to the rules for uploading scanlated releases.
    3. Any scanlated release is allowed to be uploaded, unless the release's scanlation group has enabled upload restrictions. The following restrictions also apply.
      1. Using the translated script of an official release as the basis of a scanlation is allowed only if the script has been re-translated into a different language.
      2. Using the translated script of a release by another scanlation group is generally allowed as long as there is a significant difference from the source release, such as being translated to another language, or having significantly improved typesetting or higher quality raws.
      3. Duplicate releases (as in the same chapter released by the same group) are not allowed. If you want to edit or replace a release, but you are not the original uploader or a member of the scanlation group, report the chapter with an explanation or contact staff.
      4. A scanlated joint release between multiple groups is generally allowed according to the least restrictive group. If a group in the joint has upload restrictions, contact staff before uploading.
      5. Joke or troll releases are not allowed, except on April 1st.
    4. If a group has had no releases on MangaDex or any websites affiliated with that group for a period of 6 months, the group will be considered inactive.
      1. It is possible to request a removal of inactive groups' upload restrictions.
      2. Inactive groups' "do not mirror" and other such policies can be ignored.
    5. Chapters from groups linking to group sites which adopt excessive profiteering techniques are not allowed. Examples include (but are not limited to) adblocker-blockers, pop-ups and pop-unders.
  3. Upload Guidelines
    1. File Limitations
      1. Uploaded files must be in the ZIP format (.zip or .cbz), must not exceed 100MB and must not be password protected.
      2. The archive's directory depth must be at most one. In other words, do not upload archives that have folders inside folders.
      3. Avoid filenames with ! or # as these can cause chapters to be broken on upload.
    2. Content
      1. Do not combine several chapters into a single release.
      2. Chapters that were arbitrarily split up by the scanlators may be recombined into singular whole chapters.
      3. Otherwise, if you are not part of the scanlation group, do not alter the release you are uploading by any means such as removing, editing, or adding pages.
      4. Obtrusive watermarks are not allowed.
      5. Always upload releases from the highest possible quality source, which is usually the scanlator's website. Do not upload highly compressed and watermarked releases from aggregators, unless there is absolutely no other option.
      6. Only partially uploading releases with the intention to lure users to your site for the other chapters is not allowed. Either upload all chapters, or don't upload any.
    3. Groups
      1. Only upload to the group "Unknown" if it is not possible to determine which group is responsible for the release.
      2. Only upload to the group "no group" if the scanlator does not wish to create a group.
      3. If the group does not yet exist in the database, add it here before uploading.
    4. Naming Conventions
      1. Fill in as many of the fields as possible, including chapter titles if available. If the chapter has no proper title, leave it empty.
      2. No tags to any of the fields are allowed, such as "[HQ]" to the chapter name or "v2" to the chapter number.
      3. Only add volume numbers to chapters that have already been specifically published together in a single full volume. Make sure the numbers are correct. Otherwise, the volume field should be left empty.
      4. Use decimals (1.1, 1.2, etc.) for bonus chapters/omake/etc. Depending on the amount of chapters, the decimal may have to be zero padded to the appropriate amount of digits to ensure correct sorting (1.09, 1.10, etc.).
      5. For oneshots, use "Oneshot" as the title and leave the chapter and volume numbers empty. If the oneshot is uploaded to its serialization entry, use 0 as the volume number for sorting purposes.
      6. For entries that use season numbering (such as some Korean webtoons), use the volume field for the season number.
  4. Conduct
    1. Misidentifying yourself as a MangaDex staff member will result in a ban.
    2. MangaDex does not condone contacting groups about changing their restrictions or uploading their releases. If you are contacting a group, be nice and make it clear you are not associated with MangaDex.
    3. Abusing the chapter report function could result in a ban.
    4. Do not report any releases for any translation or visual quality issues that originate from the scanlator. These reports will be ignored.
    5. Circumventing group upload restrictions in any way could result in a ban.
    6. Avoid edit wars. If another user edits a comic entry to something different from what you had previously edited and you disagree with their edit, do not change it back, but immediately notify a staff member.
    7. If you think a release has been taken down mistakenly, do not reupload. Contact staff.
