How to download manga in three steps

  1. Open a chapter

    Read as usual. On supported sites, the Koma button appears at the edge of the page.

  2. Pick your pages

    The whole chapter is selected for you. Click a page to skip it, or Shift-click to select a range.

  3. Save

    Koma downloads every page in reading order and saves the chapter to your Downloads folder, in the format you choose:

    • ZIP archive
    • CBZ comic book
    • Separate images

Everything you need to save manga offline

Built for keeping manga — not for grabbing random images.

Whole chapters, in reading order

Pages are saved in the order you read them. Nothing missing, nothing extra: ads, covers and other series are left out.

Made for webtoons and manhwa

Extra-long vertical strips get readable previews, and every strip is saved at full length.

Batch-download from the chapter list

Open the chapter list, tick the chapters you want and save them in one go. Perfect for catching up on a series.

No login, no fees

Install and go. There's no account to create and nothing to pay.

Night mode & 15 languages

A calm paper-and-ink interface that follows your system theme — in English, 日本語, 한국어, 中文 and more.

Respectful by design

Koma helps you keep what you can already read. It doesn't break the rules of the sites you love.

  • Only what you can read

    Chapters you haven't unlocked show as unavailable. Koma never tries to get around a paywall.

  • Credits stay with the work

    Chapters saved from MangaDex include a credits file naming the site and the translation group.

  • Nothing leaves your device

    Koma has no servers and no tracking. Your downloads and history stay on your computer.

Frequently asked questions

How do I download a manga chapter?

Install Koma, open the chapter on a supported site and click the Koma button at the edge of the page. Every page is selected — press Save and the chapter downloads in reading order.

Is Koma free?

Yes. Koma is a free manga downloader: every feature is free to use, and there's no account to create.

Can I download several chapters, or a whole series?

Yes. Open the series page or its chapter list, select the chapters you want in Koma and save them in one go. They download one after another, and you can pause and resume at any time.

Does Koma work with webtoons and manhwa?

Yes. Koma supports Naver Webtoon and Tapas and handles long vertical strips: previews stay readable and every strip is saved at full length.

Can I read downloaded manga offline?

Yes. Saved chapters are ordinary files on your computer, so you can read them without an internet connection, copy them to a tablet or phone, or open them in your favorite comic reader.

What format are the files saved in?

You choose: a ZIP archive, a CBZ comic-book archive (opens directly in most comic reader apps and includes chapter info), or separate image files. ZIP and CBZ keep each chapter in a single file.

Which manga sites are supported?

Shonen Jump+, Naver Webtoon, MangaDex and Tapas, plus 19 more Japanese publisher sites including Comic DAYS, Sunday Webry, Tonari no Young Jump and KadoComi — 23 sites in all. The full list is above.

What if my site isn't on the list?

Email us at [email protected] and tell us which site you'd like Koma to support.

Will Koma download paid or locked chapters?

No. Koma only saves pages that are already open to you in the reader. Chapters you haven't unlocked show as unavailable, and Koma never tries to get around a paywall.

Is Koma safe? Does it collect my data?

Koma runs entirely on your device. There's no account and no tracking, and your reading history never leaves your computer. Koma asks for permission to read the pages you open, because that's how it finds the images.
