Main features

  • You will be warned when you are going to download an already downloaded manga.
  • For manga list page:
    • Add pjax support. Changing pages will not interrupt downloads.
    • Download queue support.
    • The caption of downloaded manga will be marked with grey color.

Setting

  1. Download thread
    If you think the download speed is too slow, you can try to increase the number of download threads from this setting.
  2. Open on new tab
    Gallery page will be open on a new window by default, turn off it if you don't like it.
  3. Custom download URL
    WARNING: Please don't set this if you don't know what it does.
    Tip: You may need to add your domain into XHR security for this script.
    Provide a URL containing the following placeholder:
    • {{mid}} - Media ID
    • {{index}} - Page index, starting from 1
    • {{ext}} - Image file extension
  4. Compression filename
    Default is {{japanese}}.zip. You can custom the naming of downloaded compression file, including the file extension, such as {{english}}.cbz.
    Available placeholders:
    • {{english}} - English name of manga
    • {{japanese}} - Japanese name of manga
    • {{pretty}} - English simple title of manga
    • {{id}} - Gallery ID
    • {{pages}} - Number of pages
  5. Compression level
    Accept a numer in 0-9, default is 0.
    0 means "no compression", 1 means "best speed", 9 means "best compression".
    Actually, for manga, compression output size of 0 and 9 usually differ by less than 1%.
  6. Filename length
    Zeros will be padded to the start of image filename when its length lower than the value you specified. This can avoid the sorting confusion caused by sorting only by string in some cases.
    Accept a nonnegative integer or auto.
  7. Auto cancel downloaded manga
    When you are going to download an already downloaded manga, it will be canceled automatically instead of pop-up a confirmation box.
  8. Auto retry when error occurs
    Automatically retry when an error occurs, instead of pop-up a confirmation box.
  9. Auto show all
    Help you to click the "Show all" button on manga detail page automatically.

Other features

nHentai mirror sites support

This script also support some nHentai mirror sites such as NyaHentai. If the script does not run on some domains, you can add them to User matches, find the correct image URL and set Custom Download URL.

A bad news: This script will not be available on the manga list page of all mirror sites and the manga details page of some mirror sites in the near future. I'm too lazy to explain the full reason in English. In simple terms it's because of CloudFlare and there's nothing I can do about it.

Language filter

You can select a language in the navigation bar to filter mangas.

100% view height

Effective when reading online, only for mirror sites (now nHentai already has this feature).
