ComicFlow - CBR & CBZ to PDF

ComicFlow converts CBR and CBZ comic archives to PDF, reads them directly, and organizes your collection — 100% offline and private. No ads, no account, no subscription.

YOUR COMPUTER, YOUR LIBRARY
Two new ways to get comics onto your device, neither of which needs a cable. Both are free.

- WATCH FOLDERS: Point ComicFlow at a folder in Files, including iCloud Drive or a network share you have mounted there.
- WI-FI UPLOAD: Open one address in a browser on your computer and drag comics onto the page.

CONVERT CBR/CBZ TO PDF
Convert comic book archives to PDF with one tap. ComicFlow extracts every page from your CBR, CBZ, RAR, and ZIP files and builds a clean, correctly ordered PDF in seconds.

- Three quality settings: Low for sharing, Medium for everyday reading, High for collectors
- Batch conversion: queue multiple files and watch per-file progress

CBZ EXPORT — FREE FOR EVERYONE
Turn any comic into a standard CBZ that opens natively on Kobo, Boox, PocketBook, KOReader, and practically every comic reader app. No re-encoding, no quality loss. Included in the base app — no purchase needed.

READ COMICS DIRECTLY — NO CONVERSION NEEDED
Open CBR, CBZ, and PDF files instantly in the built-in reader, optimized for high-resolution comic pages.

- Double-tap or pinch to zoom into artwork
- Tap zones for one-handed page turns
- Reading position saved automatically for every file
- Bookmark pages and jump back anytime

ORGANIZE YOUR COLLECTION
- Custom collections for series or genres
- 5-star ratings, personal notes, and tags
- Reading status: unread, reading, completed
- Instant search; filter by publisher, year, genre, rating, or status
- ComicInfo.xml metadata read automatically

FLEXIBLE READING MODES
- Single page, double-page spread, or vertical scroll for webtoons
- Right-to-left page order for manga
- Thumbnail grid for quick navigation

iCLOUD SYNC
Reading progress, bookmarks, ratings, and notes sync across your Apple devices. Optional, no account needed — and it never uploads your comic files.

COMICFLOW PRO — OPTIONAL, ONE-TIME UPGRADE
The base app is complete and stays that way. Pro is a single in-app purchase — pay once, keep it forever, no subscription — that adds:

- Face ID-locked collections: keep private comics behind Face ID, Touch ID, or your passcode
- Reader presets: save your manga, western, and webtoon setups and switch in one tap
- EPUB export for e-readers: fixed-layout EPUB3 tuned for Kobo, Boox, reMarkable, and PocketBook, with a .kepub option for Kobo
- E-ink image optimization: auto-crop, contrast and sharpening tuned per device, grayscale palettes, double-page splitting for manga, webtoon strip splitting

An honest note on Kindle: Kindle devices don't open sideloaded EPUB files. ComicFlow's EPUB export works together with the free Calibre desktop app to get comics onto a Kindle — the app explains the exact steps instead of pretend
