Kodak KDC to JPG

KDC is a proprietary raw format written by older Kodak digital cameras. It stores the sensor data as captured and needs specialized software to open, which modern operating systems, browsers and most photo apps no longer provide. Converting to JPG makes your older photographs easy to view, share with clients or print. This tool does it by extracting the preview image stored in each file.

Drag your KDC files onto the drop area, or click it to browse; you can add several at once. Set the JPG Quality slider, which starts at 90, then click Convert to JPG. The files are processed one at a time, each showing Extracting and then Done, and every JPG downloads automatically with the original name. Click Clear List to start a new batch.

The KDC file holds the raw sensor data, with more room to recover highlights and shadows, but it is hard to open. The JPG from this tool is the camera's own rendering of the scene, taken from the preview inside the file, with the in-camera white balance and colors applied, at 8 bits per channel. It opens anywhere, but offers less flexibility for heavy editing.

Convert when easy access matters more than deep retouching: archiving old shoots, building an online portfolio, or sending past work to a client who cannot open KDC files. JPG copies are instantly viewable on any device. Keep the original KDC files on a backup drive as well, and use the JPGs for daily viewing, posting online and client delivery.

The JPG is the preview your camera rendered at the time, using its own white balance and color processing. Raw software develops the sensor data separately and may render it differently, so colors can differ from what you remember or from another program. This tool does not re-develop the raw data. For critical color, adjust white balance or tint in a photo editor afterwards.

The tool sets no file size or batch limit. Everything happens in your browser on your own device, so the only practical limit is your computer's memory, and KDC files from early cameras are small by today's standards. Files are processed one after another, so a large archive simply takes longer. If your browser feels slow, convert a few dozen files at a time.

The JPG is built from the embedded preview image alone, so none of the original metadata is copied: not the shutter speed, aperture, ISO, date taken, nor Kodak's own tags. The only thing the tool reads from the file's metadata is the orientation, which it uses to rotate the picture correctly. Keep the KDC originals if you need the shooting data.

Check that each file ends in .kdc; files sometimes lose their extensions when copied between old systems, so rename them if needed. If a file shows No preview image found, it holds no JPEG preview the browser can decode, and the tool cannot develop the raw data instead. If the preview could not be decoded, the file may be damaged; try another copy or a different browser.

Yes. The converter runs in the browser, so it works on phones and tablets as well as computers. Select KDC files from your device's storage, convert them, and the JPGs save to the device. Everything is processed locally, so no mobile data is used for the conversion itself. Large batches do take memory and storage space, so a computer is more comfortable for big archives.

Start from intact original KDC files straight from your archive. Set the JPG Quality slider high, 90 to 100, since the slider controls how strongly the extracted preview is compressed. The resolution of the result is set by the preview the camera stored, so it cannot be increased. Afterwards, avoid repeatedly re-saving the JPG, because each new save adds compression loss; edit from the first copy.
