Love reading manga online but wish you could enjoy your favorite chapters offline — on a plane, in bed, or anywhere without Wi-Fi? You're not alone. Millions of manga fans use popular online readers every day, but these platforms are online-only: once you close your browser or lose connection, your chapter is gone.
In this guide we cover the best online manga reading platforms, explain how each works, and then show you step by step how to use the free Chrome extension All Images & Manga Downloader to save any chapter as a clean, single PDF — for personal offline use.
📚 Best Online Manga Reading Sites
All the platforms below display manga in a vertical scrolling format, loading pages lazily as you scroll — which makes them ideal candidates for a smart image-capture extension. Here is a comprehensive overview of the most popular ones.
MangaPlus
MangaPlus is the official free manga platform run by Shueisha, the powerhouse Japanese publisher behind One Piece, Jujutsu Kaisen, Naruto, Dragon Ball, and My Hero Academia. It is one of the most legitimate and trusted places to read manga online.
MangaFire
MangaFire is one of the most popular unofficial manga readers, boasting a library of over 30,000 titles across every genre. It stands out for its genuinely clean, zero pop-up interface — rare among free manga sites.
Bato.to
Bato.to (also known as BATO) is a community-driven scanlation hub beloved for its extensive collection of hard-to-find titles alongside mainstream hits. It mixes fan translations with officially licensed works, making it a great discovery platform.
MangaDex
MangaDex is one of the most respected community-driven manga platforms, known for its best-in-class image quality and support for an extraordinary number of languages. Users upload scanlations and fan translations, making it a truly global library.
ComicK
ComicK stands out with its excellent user interface, minimal image compression, and advanced filtering by detailed tags and categories. It's favored by readers who want to discover new titles based on granular genre and theme filters.
Webtoon (LINE Webtoon)
Webtoon pioneered the infinite vertical scroll format now used across the industry. While technically hosting webtoons (primarily Korean) rather than traditional manga, its vast library of manga-style stories and seamless mobile experience make it essential reading for fans of illustrated serial fiction.
VIZ Media
VIZ Media is one of the leading official manga publishers in the West, offering a massive catalog of 10,000+ chapters including hits like Bleach, Naruto, One-Punch Man, and Demon Slayer. Free previews go up to 60 pages per volume.
ComicWalker
ComicWalker, powered by Kadokawa, provides a rich selection of official free manga featuring full-color chapters and exclusive series in romance, fantasy, and action. It supports vertical scrolling and multilingual options, with regular promotional events giving access to dozens of free episodes.
Other Notable Manga Sites
🔧 All Images & Manga Downloader — Overview
All Images & Manga Downloader is a Chrome extension that scans any webpage and grabs every image it can find — including tricky blob: and data: sources, classic <img src> tags, canvas-rendered images, and custom data-url attributes. It then lets you export everything either as individual files or as a single, clean PDF — perfect for offline manga reading.
📖 How to Download a Manga Chapter — Step by Step
The process is identical regardless of which manga site you use — MangaPlus, MangaFire, Bato.to, MangaDex, or any other scrolling reader. Here is the complete workflow:
Go to the Chrome Web Store page and click Add to Chrome. Once installed, pin the extension icon next to your address bar for easy access.
Navigate to your manga site of choice (MangaPlus, MangaFire, Bato.to, etc.) and open the specific chapter you want to save. Let the page fully load before proceeding.
Click the extension icon to open the popup, then press the SCAN button. The extension will automatically scroll the page top-to-bottom to trigger all lazy-loaded images, capturing them in real time into the gallery preview.
Use the Min Width and Min Height sliders to filter out small images like avatars, icons, and ad banners. For manga pages, a minimum of 300–400px on both axes usually works well to keep only the full-size panel images.
Use Select All to grab everything, or click individual checkboxes to select specific pages. The live gallery lets you preview each image before exporting, so you can deselect anything you don't need.
Choose your export mode:
The extension stores original images in IndexedDB locally in your browser, so even if you close the popup and reopen it later, your previously scanned images are still there at full resolution — ready to export without needing to rescan the page.
