DCR to CBZ Converter
FileFlip converts DCR 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 a DCR file to CBZ?#
- Drop your DCR 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 DCR to CBZ lose quality?#
No. The DCR 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 DCR files online?#
Yes, because nothing is uploaded. FileFlip converts DCR 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 DCR to CBZ actually does to the file#
Converting DCR 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.
| Engine | ImageMagick and MuPDF |
|---|---|
| Conversion path | 2 steps: DCR → 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 |
Worth knowing before you start:
- camera raw is demosaiced with ImageMagick's defaults, which will not match the camera's own rendering
- the picture is placed in the document as a picture; no text is recognised out of it
- some cameras write lossily compressed raw, so the source is not always a complete sensor record
What is a DCR file?#
A DCR file stores raw, TIFF-based sensor data from Kodak's professional DCS-series digital SLRs, the raw format Kodak wrote on cameras from the original 1991 DCS 100 through models like the DCS 760 and DCS Pro Back Plus.
There's no reason to shoot DCR today; it only matters when opening or archiving images captured on a Kodak DCS-series camera.
Convert DCR to DNG or TIFF for long-term storage, since Kodak's DCS bodies are long discontinued and fewer raw converters keep testing against the format.
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.
DCR to CBZ questions people ask#
What camera made this DCR file?
A DCR file was written by a Kodak DCS-series professional digital SLR, the line Kodak built on Nikon and Canon film bodies from 1991 to 2005. The exact model, such as a DCS 760 or DCS Pro Back Plus, is recorded in the file's TIFF metadata.
What still opens a DCR file today?
DCR files open in raw converters built on the LibRaw library, such as RawTherapee and darktable, which keep support for Kodak's DCS-series cameras. Kodak's own DCS software, which originally handled the format, is no longer maintained.
What should I convert a DCR file to for long-term storage?
Convert DCR to DNG or TIFF, since both are widely supported archival formats and DCR support in current software depends on a shrinking set of raw converters that still recognize a discontinued camera line.
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.
