- Update to Chromium 112.0.5590.0.
- Better support for BW books page number pattern, support novels.
Download it in the release or here: Windows x64 release build v0.3.3
This version has some good features below for BW:
- Could download the cover (If the cover image is jpeg, please check it or better convert it to png before you share it, because the jpeg file will contain your BW account info).
- Could name the image automictically using the page number, you can start at any page you want and go forward or go back!
- Could name the folder with the BW uuid but not a random one anymore.
- No more blank or repeating page will be skipped, no more image hash to check repeating page, better performance.
If you find the file name all become "cover_or_extra_xxx" when downloading some manga, please file a bug, there may be more URL patterns in BW than I have seen or they changed the pattern, it should be covered to make the page number working correctly.

Pump Chromium to 109.0.5393, may fix some problems.
Download it in the release or here: Windows x64 release build v0.2.1
This version is based on Chromium 106.0.5243.0, the changes are below:
- Support
https://ebook.tongli.com.tw
, will save the downloaded images in theC:\bw_export_data\TONGLI_URL_STRING
- Support
https://www.dlsite.com
, but this is saving the cache images, so the final 3~4 pages should be downloaded as below (for example we have 10 pages):- Go through page 1 to 10 (Make sure the current page is full loaded when you go to next page).
- You will find that at page 10, there are maybe only images for page 1-7.
- Go back from page 10 to page 5, you will find that the final pages are saved. (but maybe in reverse order)
- Currently we could not do anything better than this.
- Works for
https://book.dmm.com
, use the script below to move page:
window.i=0;setInterval(()=>{NFBR.a6G.Initializer.views_.menu.options.a6l.moveToPage(window.i);console.log(window.i);window.i++;},3000)
The script above is for DMM, for BW please use the script below:
window.i=0;setInterval(()=>{NFBR.a6G.Initializer.L7v.menu.options.a6l.moveToPage(window.i);console.log(window.i);window.i++;},3000)
- Maybe slitely faster for BW and may download some images that width > height.

Press
F12
, make it a separate window (see the image below) and run the script below (just go toconsole
and copy-past the code, press enter) to move the page automatically, if your network is good, you can change the3000
to a smaller number, 3000 means 3000ms -> 3s, every 3s it will move to the next page.You can also manually click the mouse left button / use a keyboard arrow key / use a keyboard simulation software to move the page, you can choose the way you like, just make sure the page is moving.
window.i=0;setInterval(()=>{NFBR.a6G.Initializer.L7v.menu.options.a6l.moveToPage(window.i);console.log(window.i);window.i++;},3000)
If this not work and show 'Uncaught TypeError: Cannot read properties of undefined (reading 'menu') at :1:54', it means BW has updated the js, you can try to find it in the console, just try
NFBR.a6G.Initializer.*.menu
is notundefined
and the * is the new object name; Or you can just file a bug. -
Now you can check your
C:\bw_export_data
, you can find a random uuid folder with all the manga images in it.
If you want to download multiple manga at the same time, just open as many manga as you want, and do the step 5 to 6.
This method is very easy to use, stable and no need to find any resolution or cookies, and it can download the real original image with no barcode.
Maybe will add a new browser ui to it and can click to download in the future.
May not download the cover page now.
Only built on windows, no program now for other platform.

The URL is start with member.bookwalker.jp, not the viewer.bookwalker.jp. Here we use the manga 【期間限定 無料お試し版】あつまれ!ふしぎ研究部 1.

Just copy this URL to the
MANGA_URL
in main.py. -
-
After edit the program, run
python main.py
to run it.

The
SLEEP_TIME
by default is 2 seconds, you can adjust it with your own network situation, if the downloading has repeated images, you can change it to 5 or more. If you think it's too slow, try change it to 1 or even 0.5. -
LOADING_WAIT_TIME = 20
, this is the time to wait until the manga viewer page loaded, if your network is not good, you can set it to 30 or 50 seconds. -
Resolution, you can change it as you want, but check the original image resolution first.
RES = (784, 1200)
If the original image has a higher resolution, you can change it like this (The resolution is just a example).
RES = (1568, 2400)
For [Cmoa.jp] no need this, the resolution is fixed by [Cmoa.jp].
-
Some time we should log out and log in, this website is very strict and take so many method to prevent abuse.
-
Now you can cut the image by setting
CUT_IMAGE
to (left, upper, right, lower).For example you want to cut 3px from the bottom of image, you can set it to:
CUT_IMAGE = (0, 0, 0, 3)
This function use
Pillow
, if you want to use it, you should install it by using the command:pip install Pillow
By default it is
None
, means do not cut the image. -
You can now change the file name prefix and number of digits by changing
file_name_prefix
andnumber_of_digits
.For example, if you are downloading Kill La Kill Manga Volume 1, and you want the file name like:
KLK_V1 │--KLK_V1_001.jpg │--KLK_V1_002.jpg │--KLK_V1_003.jpg
Then you can set the parameters like below:
settings = { ..., 'file_name_prefix': 'KLK_V1', # File name digits count, if you want your file name like '001.jpg', write 3 here. 'number_of_digits': 3 }
-
Concept
To download Manga, normally we do like this:
+------------+ +-----------+ +------------+ +-------------------+ +--------------+ | | | | | | | | OVER | | | Login +-----+ Load page +----->+ Save image +----->+ Move to next page +----->+ Finished | | | | | | | | | | | +------------+ +-----------+ +-----+------+ +---------+---------+ +--------------+ ^ | | | | More page | +-----------------------+
So we can create a framework to reuse the code, for new website, normally we only need to write some of the method.

Introduction to abstract
WebsiteActions
class.For each website, the class should have the following methods/attributes, here we use bookwalker.jp as example:
class BookwalkerJP(WebsiteActions): ''' bookwalker.jp ''' # login_url is the page that we load first and put the cookies. login_url = 'https://member.bookwalker.jp/app/03/login' @staticmethod def check_url(manga_url): ''' This method return a bool, check if the given manga url is belong to this class. ''' return manga_url.find('bookwalker.jp') != -1 def get_sum_page_count(self, driver): ''' This method return an integer, get total page number. ''' return int(str(driver.find_element_by_id('pageSliderCounter').text).split('/')[1]) def move_to_page(self, driver, page): ''' This method return nothing, move to given page number. ''' driver.execute_script( 'NFBR.a6G.Initializer.B0U.menu.a6l.moveToPage(%d)' % page) def wait_loading(self, driver): ''' This method return nothing, wait manga loading. ''' WebDriverWait(driver, 30).until_not(lambda x: self.check_is_loading( x.find_elements_by_css_selector(".loading"))) def get_imgdata(self, driver, now_page): ''' This method return String/something can be written to file or convert to BytesIO, get image data. ''' canvas = driver.find_element_by_css_selector(".currentScreen canvas") img_base64 = driver.execute_script( "return arguments[0].toDataURL('image/jpeg').substring(22);", canvas) return base64.b64decode(img_base64) def get_now_page(self, driver): ''' This method return an integer, the page number on the current page ''' return int(str(driver.find_element_by_id('pageSliderCounter').text).split('/')[0])
We also have a
before_download
method, this method run before we start download, because some website need to close some pop-up component before we start downloading.def before_download(self, driver): ''' This method return nothing, Run before download. ''' driver.execute_script('parent.closeTips()')
