XCF to CBZ Converter
FileFlip converts XCF to CBZ entirely inside your browser, using ImageMagick 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 XCF file to CBZ?#
- Drop your XCF 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 24.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick 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 XCF to CBZ lose quality?#
No. The XCF picture is placed into the CBZ document at its full resolution, so every pixel reaches it intact. What you give up is that it becomes a picture inside a document rather than text.
Is it safe to convert XCF files online?#
Yes, because nothing is uploaded. FileFlip converts XCF 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 XCF to CBZ actually does to the file#
Converting XCF to CBZ runs on ImageMagick and MuPDF, downloads 24.1 MB of WebAssembly the first time and nothing after that, places the picture into the document at full resolution, and drops layers and extra images.
| Engine | ImageMagick and MuPDF |
|---|---|
| Conversion path | 2 steps: XCF → PNG → CBZ |
| Downloaded to your browser | 24.1 MB, once, then cached by your browser |
| Quality | Pixels preserved |
| 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 |
|---|---|---|
| Layers | Dropped | The target format has nowhere to put it. |
| Extra images | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- ImageMagick is asked for a single image, so only the first frame, page, or icon size is read
- the picture is placed in the document as a picture; no text is recognised out of it
What is an XCF file?#
An XCF file is the working document format GIMP saves to, keeping an image's layers, layer masks, channels and paths independently editable instead of merging them into one picture.
Keep a project as XCF while it's still being edited in GIMP, so layers, masks and paths stay available for later changes.
Convert XCF to PNG or JPEG once the image is finished and needs to be viewed or shared outside GIMP, since almost nothing else reads the layered file.
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.
XCF to CBZ questions people ask#
Can Photoshop open XCF files?
No, Photoshop doesn't support XCF natively. GIMP itself is the only editor with full-fidelity support, though the browser-based Photopea can open XCF files with much of their layer structure intact.
What happens to my layers when I export XCF to PNG or JPEG?
Exporting an XCF file to PNG or JPEG merges every layer into one flat image, bakes layer masks and channels permanently into the pixels, and rasterizes any text so it can no longer be edited. Paths and guides are dropped entirely, since neither format has anywhere to store them.
Why won't GIMP open my old XCF file, or an old GIMP open a new one?
XCF's structure has changed across GIMP versions: layer groups, added in GIMP 2.7, won't open in GIMP 2.6 or earlier, and a text layer created in modern GIMP degrades to a flat rasterized layer if opened in GIMP 1.2. Saving from a newer GIMP generally isn't safe to assume an older GIMP can read.
What's the difference between XCF and OpenRaster?
XCF is GIMP's own internal working format, built to mirror GIMP's internal engine and prone to changing between versions, while OpenRaster (.ora) is a format GIMP helped develop jointly with Krita specifically for interchange between different programs. GIMP's own documentation recommends OpenRaster over XCF when a layered file needs to move between tools or be archived long-term.
