What offline means for a manga reader
A reader shows one page at a time, and each page is an image. Offline works when those images are on the phone already. That gives you two kinds of copy to choose between.
- Downloads inside a reader app. Nothing to organize.
- Your own files in a reader that opens them. Organize them how you like; you decide where the files and their backup live.
There is a third case that is not a copy at all: a comic that is only in cloud storage. That is reading from storage you own, and it needs a connection. It has its own section below, because the question it answers is where your library lives, not what you keep on the phone.
Downloads inside a reader app
Mihon documents this side, so it is the example here. Everything in this section comes from its own pages, not from our testing; each app's documentation is the final word on its own behaviour.
Mihon manages its automatic backups, chapter downloads and Local source within one storage location you select (Mihon's storage FAQ, read 2026-10-01). Downloads land in a source folder, then a series folder, then one .cbz file per chapter; its downloads FAQ gives the layout as downloads/Source Name/Manga Name/Chapter Name (abcdef).cbz (Mihon's downloads FAQ, read 2026-10-01). Those files are on the phone, so downloaded chapters read offline.
Mihon's guide says to place series in the local folder of the storage location. Mihon's local source guide says a chapter is a folder of pictures or an archive file, lists ZIP/CBZ, RAR/CBR and EPUB as the archive formats it takes, and adds that directories and ZIP/CBZ perform better (Mihon's local source guide, read 2026-10-01). A single folder or archive is a single chapter.
Downloads and the local folder both sit in that one storage location. Mihon's library FAQ says to enable "Download only" via More → Downloaded only when you only want to read downloaded chapters, and to turn on download badges under Library → Filter → Display tab to see the number of downloaded chapters (Mihon's library FAQ, read 2026-10-01).
The catch is ownership of the copy. The files are on the phone, but they live in the app's layout, and what carries them to the next phone is a separate question. Mihon's backup guide answers it: a backup holds the library and the settings, and "Downloaded chapter files including local source chapters" are listed under what is not included (Mihon's backup guide, read 2026-10-01).
Your own files in a reader
If the comics are already your files, the phone copy is the file itself. Copy the CBZs into a folder, point a reader at it, and the copy is as portable as any other file on the phone. What is a CBZ file, and how do you read one? covers the format and how to convert other archive types to it.
Formats decide which reader you can use. Easemic (a free Android app in invite-only testing) imports CBZ and plain ZIP archives and folders of images from the phone; it does not open CBR, CB7 or PDF. Imported comics are read from the phone and are never uploaded to storage. Mihon's local source takes the wider list its guide documents, including RAR/CBR and EPUB (Mihon's local source guide, read 2026-10-01).
What happens to the offline copy when the phone changes
Google's own help for moving to a new Android phone lists "Apps and certain app data" among what copies during setup, and lists "Downloads, like PDF files" and "Data from apps that don't use Android backup" among what will not (Google's transfer help, read 2026-10-01). What an app does with its own downloads folder is that app's question, and Mihon's backup documentation answers it.
Mihon's answer is to move the downloads folder yourself: its backup guide says to "Transfer or move your previously downloaded chapters into the 'downloads' folder of your set Storage location" and then tap "Reindex downloads" in More → Settings → Advanced (Mihon's backup guide, read 2026-10-01). Your own CBZ files are ordinary files: copy the folder over like any other folder.
If the library lives in storage you own instead, a new phone is not a move. Connect the new phone to the same storage and the collected comics come back; on the new phone they read from storage until you download them. Comics that were only imported do not come back through storage: copy the folder over and import it again. Reading progress, bookmarks, history and settings travel in a one-file export, and its fuller option carries downloaded comics too. How to move a comic library to a new phone covers both routes in full.
Reading from storage you own
In Easemic, a comic can be collected into your cloud library in storage you own: S3-compatible storage, WebDAV, OneDrive or Google Drive. With storage connected, collect fetches the comic's pages to the phone, then uploads them to your storage. It can also be downloaded straight to the phone, and the two are separate actions (checked in the app, 2026-10-01).
By default the phone keeps its copy of a collected comic, so a comic collected on this phone reads offline too, and a comic you only downloaded reads offline as well. Only a comic that is in storage but not on this phone needs a connection: one collected on another phone, one on a new phone connected to the same storage, or one whose phone copy the "Keep only the cloud copy" setting cleared after upload. Download puts a copy on the phone, and reading uses the phone copy whenever there is one.
What storage adds is a library that survives the phone. Reading a comic that is only in storage takes a connection, and how much that matters depends on the storage: How fast is reading comics straight from your own cloud? has our measured page times per service, and What is WebDAV, and which drives support it? covers which drives work for this at all.
A checklist before a flight
- Decide which comics are coming, and which copy each one gets. A comic that is only in your storage is not on the phone; with the "Keep only the cloud copy" setting on, the phone copy of a collected comic is cleared once it has uploaded, so check that setting too.
- Get the copies onto the phone while you still have a connection: open the comic and tap Download (in Easemic, a comic you collected on this phone is already there by default; a comic that is only in your storage needs Download first), or copy your own CBZ and ZIP files and image folders across.
- Check the free space first: a CBZ holds its pages as image files.
- Prove it: turn on airplane mode and open each one. In Mihon, More → Downloaded only is the library FAQ's answer to reading only downloaded chapters (Mihon's library FAQ, read 2026-10-01).
Questions people ask
Can you read manga without internet?
Yes, when the pages are already on the phone: downloaded comics, your own imported files, and in Easemic a comic collected on this phone, because the phone keeps its copy by default. A comic that is only in your cloud storage needs a connection until you download it.
Where do downloaded manga go on Android?
In Mihon, its documentation says downloads are stored as downloads/Source Name/Manga Name/Chapter Name (abcdef).cbz under the storage location the app uses. Every app decides its own layout, so the app's own docs are the final word.
What happens to downloaded manga on a new phone?
Google's transfer help lists "Data from apps that don't use Android backup" among the things that will not copy during setup, and Mihon's documentation says its backups do not include downloaded chapter files. Mihon tells you to move the downloads folder yourself and tap "Reindex downloads".
Can you read a Google Drive or WebDAV manga library offline?
In Easemic, comics downloaded to the phone read offline, and a comic collected on this phone also reads offline because the phone keeps its copy by default. A comic that is only in your storage reads from storage and needs a connection until you download it.
Does Easemic work without internet?
For comics that are on the phone, yes: comics downloaded to the phone, comics collected on this phone (the phone keeps its copy by default), and imported files all read offline. Comics that are only in your storage need a connection. Easemic is a free Android app in invite-only testing.
