FAQ 💬

Where can I get the manga link?

You can find the manga link at mangadex.org. Choose the manga you like and open its page. The link to the manga looks like this:

https://mangadex.org/title/abc-123-abc/some-title

You can use this link to download chapters of the manga.

Where can I get the chapter link?

Go to mangadex.org, choose the manga you like, and open the specific chapter you want. The link to the chapter looks like this:

https://mangadex.org/chapter/abc-123-abc

You can use this link to download the specific chapter.

I can't download chapter X of manga X. Why?

Make sure you have specified the correct language, translation group, and number of chapters. If you are unable to download a specific chapter, try using the direct link to the chapter:

mdx dl https://mangadex.org/chapter/abc-123-abc

Remember: mdx can only download chapters from MangaDex.

Why is downloading so slow?

I don't know. It's a problem on MangaDex's side or on your side.

I downloaded a chapter but the output filename doesn't have the volume number or chapter number. Why?

This problem stems from the uploader failing to specify the correct volume or chapter details.

Why do pages in the PDF have different sizes?

The size of each page in the PDF corresponds to the size of the image.

Getting error "While getting manga chapters: request is failed". I can't download anything. Why?

This issue is related to the MangaDex API (https://api.mangadex.org/docs/2-limitations/#general-rate-limit), mdx is sending too many requests per second. Try downloading chapters later.

Getting error "Chapters x-y not found, try another range, language, translation group etc."

Maybe you didn't specify the translation group, chapter range, or language correctly. Make sure that the chapter can be opened on MangaDex (not on external resource).

Sometimes it doesn't download because of some problems on the MangaDex side. Just try again later.

Getting an error in interactive mode when searching for manga. Why?

Because your query should be more than 5 characters to avoid errors.
