What Happened: The Official Shutdown Timeline
Amazon announced the retirement quietly, through a KDP support article titled 'Kindle Comic Creator and Kindle Kids' Book Creator will be unavailable from March 18, 2025.' Two dates matter. February 6, 2025: the download links came off Amazon's site, so new users can no longer install the tool through official channels. March 18, 2025: KDP stopped accepting the MOBI files the tool produced for new fixed-layout submissions. Amazon's stated direction is that fixed-layout books — comics, manga, picture books — should now be built as EPUB or in Kindle Create, which outputs KPF (Kindle Package Format). There was no dramatic sunset post; like a lot of legacy KDP tooling, it simply aged out. The tool had been showing its age for years — the interface dated to 2013, and the MOBI/KF8 formats it produced were deprecated across the wider Kindle ecosystem well before the official cutoff.
If You Still Have It Installed: What Works and What Doesn't
The shutdown removed the download, not the software. An existing installation of Kindle Comic Creator still opens, and old .kc2 project files still load. What changed is the destination: a MOBI export from the tool is no longer accepted for new KDP submissions, which makes the tool a dead end for publishing even where it technically runs. Books you already published through it stay live — the retirement affects new submissions, not your existing catalog. The practical read: finish nothing new in Kindle Comic Creator. If you're mid-project, export your source pages (the original JPG/PNG/PDF art, not the compiled ebook) and rebuild the package in one of the current paths below. Budget an afternoon; the migration is mostly re-importing pages and re-marking panels.
The 2026 Workflow: Three Paths onto Kindle
Publishing a comic to KDP in 2026 is a two-stage problem — produce the pages, then package them. The packaging stage now has three viable routes, and which one you pick depends on how much control you need over panel navigation and layout.
Kindle Create (Amazon's official replacement)
Amazon's current first-party tool, free on Windows and Mac. Import your page images, and Kindle Create builds a fixed-layout book with Guided View — the panel-by-panel cinematic reading mode that was Kindle Comic Creator's signature feature. Output is KPF, which uploads directly to KDP with the fewest surprises in review. This is the default choice for most self-publishers: actively maintained, officially supported, and the Guided View editor is genuinely better than the old tool's version.
Fixed-layout EPUB (the portable option)
KDP accepts fixed-layout EPUB for comics, and EPUB has one big advantage over KPF: the same file also works on Kobo, Apple Books, and most other storefronts. If you're publishing wide rather than Kindle-exclusive, building one EPUB beats maintaining per-store packages. The tradeoff is tooling — you'll be working in something like Sigil, Calibre, or InDesign's EPUB export rather than a comic-specific editor, and Guided View behavior is less predictable than with KPF.
Print-ready PDF (for paperback comics)
If your comic is going to paper as well as screen, KDP's print side takes a PDF with proper bleed and trim. Most comic self-publishers ship both: KPF or EPUB for the ebook edition, PDF for print-on-demand. The page art is identical; only the packaging differs. Do the ebook first — print review is stricter, and fixing art after a print rejection is more painful than fixing it after an ebook one.
The Part No Packaging Tool Solves: Making the Pages
Kindle Comic Creator never made comics — it packaged comics you'd already drawn. That distinction confused a steady stream of KDP hopefuls for a decade, and it still applies to Kindle Create today. The pages themselves have to come from somewhere: a traditional art workflow (Clip Studio, Procreate, a hired artist) or, increasingly, an AI comic generator that renders finished panels from a script. The AI route matters for exactly the audience Kindle Comic Creator served — writers with a story and no drawing hand. A modern AI comic book generator produces the script breakdown, keeps characters consistent across panels via a reference image, and exports clean PNGs sized for comic pages; from there, a page layout tool arranges panels into print-and-ebook-ready pages, and Kindle Create packages the result. Writer to published Kindle comic, no artist commission in the loop. For longer works, the same pipeline scales to a full graphic novel — chapters, recurring cast, consistent style — which is precisely the kind of project that used to stall at the 'I can't afford 120 pages of art' stage.
Migration Checklist for Kindle Comic Creator Refugees
One: locate your source art — original page images, not the compiled MOBI. If all you have is the MOBI, Calibre can usually extract the images, but treat that as a last resort since you'll lose resolution to the old compression. Two: install Kindle Create and re-import the pages in reading order. Three: re-mark your Guided View panels — panel regions don't migrate from .kc2 projects, so this is the manual step to budget time for. Four: preview on an actual device or the Kindle Previewer app, checking double-page spreads and the panel order on a phone-sized screen. Five: upload the KPF to KDP as a new edition of your book. Your reviews, sales rank, and ASIN stay with the listing when you update the interior file rather than creating a new listing.
