KDC to BMP Converter
FileFlip converts KDC to BMP entirely inside your browser, using ImageMagick 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 KDC file to BMP?#
- Drop your KDC 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 BMP and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the BMP file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting KDC to BMP lose quality?#
No. Converting KDC to BMP writes the data out again without discarding any of it, so nothing that was in the KDC file is lost on the way. What changes is the size of the file, not what is inside it.
Is it safe to convert KDC files online?#
Yes, because nothing is uploaded. FileFlip converts KDC 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 KDC to BMP actually does to the file#
Converting KDC to BMP runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, writes the data out again without discarding any of it.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: KDC → BMP |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossless |
| 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
- some cameras write lossily compressed raw, so the source is not always a complete sensor record
What is a KDC file?#
A KDC file holds raw sensor data from a Kodak camera, though the extension covers two unrelated file structures: an older TIFF-based format used on 1990s DC-series models like the DC40, DC50 and DC120, and a separate format Kodak reused on later EasyShare P-series and Z-series cameras.
KDC only matters when opening images pulled from an old Kodak DC-series or EasyShare P/Z-series camera; there is no reason to create one today.
Convert KDC to DNG or TIFF for long-term storage, since Kodak's cameras are discontinued and support for the older of the two KDC variants is thin in current software.
What is a BMP file?#
A BMP file holds a device-independent bitmap: a pixel grid stored with a Microsoft-defined header and, in the overwhelming majority of BMP files in the wild, no compression at all.
Use BMP when a Windows-native application, printer driver, or legacy tool specifically expects it, or when pixel data has to be stored with zero encoding overhead for a processing pipeline.
Convert BMP to PNG or JPEG for anything leaving that pipeline, since both produce a far smaller file and PNG matches BMP's lossless, generation-safe quality.
KDC to BMP questions people ask#
What camera made this KDC file?
A KDC file was written either by a 1990s Kodak DC-series camera such as the DC40, DC50 or DC120, or by a later Kodak EasyShare P-series or Z-series camera. The two eras use different internal structures despite sharing the same extension.
What still opens a KDC file today?
KDC files open in raw converters built on the LibRaw library, such as RawTherapee and darktable, which list both the older DC-series and the later EasyShare P and Z-series models among their supported cameras.
What should I convert a KDC file to for long-term storage?
Convert KDC to DNG or TIFF, since Kodak stopped making cameras in 2012 and DNG or TIFF will stay readable long after raw converters drop support for a discontinued camera line.
Why are BMP files so much bigger than JPEG or PNG?
Most BMP files store every pixel's color value directly with no compression, so a BMP is close in size to the raw uncompressed image data. JPEG and PNG both apply compression, lossy in JPEG's case and lossless in PNG's, which is why the same photo saved as either is a fraction of the size of a BMP.
