TWiki to CBZ Converter
FileFlip converts TWiki 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 a TWiki file to CBZ?#
- Drop your TWiki 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 TWiki to CBZ lose quality?#
Not in the sense of pixels or samples. Converting TWiki 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 TWiki files online?#
Yes, because nothing is uploaded. FileFlip converts TWiki 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 TWiki to CBZ actually does to the file#
Converting TWiki 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: TWiki → 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 a TWiki file?#
A TWiki file holds a wiki topic written in TWiki markup, the plain-text syntax the TWiki enterprise wiki engine uses to store a page before rendering it as HTML.
Leave a topic as TWiki markup only while it still lives inside a running TWiki or Foswiki installation that renders it.
Convert TWiki markup once its content needs to leave an aging or decommissioned TWiki install, since almost nothing outside TWiki and Foswiki reads it.
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.
TWiki to CBZ questions people ask#
What is a .twiki file?
A .twiki file holds one topic's worth of TWiki markup, the plain-text syntax TWiki uses to store wiki pages before turning them into HTML. TWiki itself doesn't normally export topics with this extension; it shows up when a topic has been dumped to a file for backup, migration or conversion.
Is TWiki still maintained?
TWiki's own site is still online, but its last software release was version 6.1.0 in July 2018. In 2008 most of the original developers split off to start Foswiki instead, which is the actively maintained continuation most TWiki installations have since migrated to.
What's the difference between TWiki and Foswiki?
Foswiki is the fork that most of TWiki's developer community started in 2008 after a dispute over the project's direction, and it has been developed continuously since. Foswiki still reads TWiki markup, so a TWiki topic generally opens correctly in a Foswiki installation without changes.
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.
