Org to CBZ Converter
FileFlip converts Org to CBZ entirely inside your browser, using Pandoc and MuPDF compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an Org file to CBZ?#
- Drop your Org file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to CBZ and the conversion starts on its own. FileFlip downloads 65.8 MB of WebAssembly the first time and nothing after that, then runs Pandoc and MuPDF on your own machine.
- Save the CBZ file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting Org to CBZ lose quality?#
Not in the sense of pixels or samples. Converting Org to CBZ rebuilds the file in CBZ's own model rather than re-encoding it, so everything CBZ can represent comes through exactly and anything it cannot has to be dropped. Expect the words to come through exactly and the page breaks to move.
Is it safe to convert Org files online?#
Yes, because nothing is uploaded. FileFlip converts Org files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What Org to CBZ actually does to the file#
Converting Org to CBZ runs on Pandoc and MuPDF, downloads 65.8 MB of WebAssembly the first time and nothing after that, rebuilds the file in the target's own model, keeps selectable text, and drops page layout.
| Engine | Pandoc and MuPDF |
|---|---|
| Conversion path | 2 steps: Org → HTML → CBZ |
| Downloaded to your browser | 65.8 MB, once, then cached by your browser |
| Quality | Rebuilt in the target's model |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Selectable text | Kept | Carried through into the converted file. |
| Page layout | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- reflowable input is laid out on a fixed 595x842pt page at 11pt before anything else happens
- the file passes through HTML on the way, so anything HTML cannot express does not survive
What is an Org file?#
An ORG file holds Org mode markup, Carsten Dominik's 2003 outlining format for Emacs where headings can double as a to-do list, an agenda entry and, through Org Babel, an executable code block, none of which survive being read as plain markup elsewhere.
Use Org mode inside Emacs for notes that mix prose, a to-do list and code you actually want to run, not just display.
Convert Org to Markdown or another format when sharing the content outside Emacs, since the agenda, TODO states and live code execution have nowhere to go in plain markup.
What is a CBZ file?#
A CBZ file is a ZIP archive of page images, usually JPEG or PNG, named so they sort into reading order, with nothing else defining it as a comic beyond that convention.
Use CBZ to distribute a scanned or digital comic as sequential page images that any comic reader opens without conversion.
Convert CBZ to PDF when a comic needs to move into software that expects a page-based document instead of a folder of images.
Org to CBZ questions people ask#
What is an ORG file and what opens it?
An ORG file is plain text written in Org mode, Emacs' outlining and notes format, so any text editor shows the raw markup. Reading it as intended, with folded headings, clickable links and a working agenda, means opening it in Emacs, which has Org mode built in.
What happens to Org mode's to-do lists and agenda when converting to another format?
Org's TODO keywords, scheduling and the agenda view are Emacs features layered on the heading structure, not separate data the file carries independently. Converting an Org file to Markdown or another format keeps the heading text but drops the TODO state, deadlines and agenda integration, since the target format has no equivalent concept.
Can Org files run code?
Yes. Org Babel lets a code block inside an Org file be executed directly in Emacs, in dozens of supported languages, with the output inserted back into the document next to the source. This literate-programming behavior is specific to Org mode and does not carry over when the file is exported or converted.
What is a CBZ file?
A CBZ file is a ZIP archive holding a comic's pages as individual image files, named so they sort into the right reading order. There is no page-layout data or text encoding involved, which is the entire format: a comic reader just opens the ZIP and displays the images in sequence.
