Fill in comic book metadata from the Grand Comics Database as you convert
A run of single issues or trades converted without metadata lands on the reader as a pile of filenames: no series, no issue number, a generic cover, the volumes in whatever order the names sort. The metadata lookup fixes that for western comics the way the AniList lookup does for manga. Flip the Manga | Comic toggle in the Metadata tab to Comic, search the title, confirm the match, and the series, issue number, writer and artist credits, publisher and cover art come back from the Grand Comics Database™ (https://www.comics.org/) and are written into the file as it converts.

What gets written depends on the output. For CBZ, the accepted record becomes a ComicInfo.xml inside the archive, the standard the comic readers and library servers already understand. For EPUB and KEPUB, the series and credits go into the book’s own metadata so a Kindle or Kobo groups the volumes and shows the cover. Drop a CBZ, CBR, ZIP, RAR, 7Z or PDF and open the Metadata tab in the studio.

How the comic lookup works
Open the Metadata tab and switch to Comic
The Manga | Comic toggle sets which catalogue the search opens on. A file you have called a comic opens on the comics results; the series name parsed from your filename seeds the search, so most files need no typing.
Confirm the match
Results arrive with cover thumbnails and the database each came from, so a same-named series is easy to tell apart. Nothing is applied until you pick one.
Review the fields against your file
Series, issue, credits, publisher and cover are shown as a change against what the file already carries, each labelled with its source. Take the whole record or only the fields you want; the volume number is read from your file, not the database.
Convert with it embedded
For CBZ output the record is written as ComicInfo.xml inside the archive. For EPUB and KEPUB it is written into the book metadata, and chapter bookmarks become real chapter entries. Download, or fetch the file on the reader from your Reader Shelf.
Comics belong on the big screens
A single issue page is wider than a manga page and reads best on a Kindle Scribe, a Kobo Elipsa or a reMarkable. The comics-for-eink page covers sizing a run for those; the lookup works the same whichever device you pick.
Optional, always
The conversion runs perfectly well with no lookup at all. This exists for libraries where grouping, credits and covers matter, which in practice means a run of more than a handful of issues.
Frequently asked questions
Which database is behind the Comic side?
The Grand Comics Database™ (https://www.comics.org/), the volunteer-built catalogue of western comics, single issues and collected editions. Its data is used under a Creative Commons Attribution-ShareAlike licence, which is why it is named wherever its records appear here. Manga comes from AniList on the other side of the toggle.
Does it write a ComicInfo.xml?
For CBZ output, yes: the accepted record is built into a ComicInfo.xml and carried through into the archive, with the series, number, summary, writer and other credits in the standard fields, so Komga, Kavita, Calibre and the desktop comic readers pick it up. For EPUB and KEPUB the same facts go into the book’s own metadata instead, which is what the Kindle and Kobo libraries read.
My file already has a ComicInfo.xml. Is it kept?
The record written into the output is the one you accepted in the Metadata tab, so a file whose upstream ComicInfo you did not touch does not carry it into a CBZ; the converter only keeps a ComicInfo it wrote for metadata you explicitly accepted. The reason is a known Kobo quirk: a ComicInfo inside a CBZ can upset Kobo’s native reader, so it is written only when it is worth that risk.
Will the issues group as a series on my Kindle?
Grouping needs a series name and a number in the file, and that is what the EPUB metadata carries after the lookup. The issue number is read from your filename, so a consistent naming pattern across the run still pays off; the lookup supplies the series-level facts.
Does the cover come from the database too?
When the matched record has cover art it is offered as a suggestion next to your file’s current cover, served from our own cover cache rather than the database’s servers. Accept it and the converted file carries that cover; decline it and the file keeps the page it had.
Conversion runs on Kindle Comic Converter (KCC), the open-source engine comic readers have relied on for years. The lookup sits in front of it and queries the Grand Comics Database™ (https://www.comics.org/), whose data is used under a Creative Commons Attribution-ShareAlike licence, and AniList for manga.
