What happens when you convert DCR to PDF
- The DCR is developed by LibRaw, the open-source camera RAW decoder, on our conversion server: the sensor data is turned into a full-colour picture with the white balance the camera recorded, AHD demosaicing and standard sRGB colour.
- ImageMagick then saves it on a PDF page the size of the photo, JPEG compressed at 92 percent quality, at the camera's full resolution, 8 bits per channel. The photo is turned the way the camera was held.
- This is a neutral, straight development, much like the camera's own JPG settings switched off: no lens corrections, noise reduction or creative styles are applied, so it can look flatter than an edited version.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert DCR to PDF online
- Press "Choose DCR files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to PDF". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each PDF with its download button. Our server has already deleted both your DCR and the PDF by then.
Why convert DCR to PDF?
DCR files usually come from Kodak professional DCS cameras such as the DCS Pro 14n. People convert them to PDF because a PDF looks the same on every device and is what forms, portals and printers ask for.
In short, DCR is good at what it was made for, and PDF is the more practical choice when the file has to open, upload or print somewhere else. DCR does not open in browsers; Lightroom, darktable and RawTherapee open it, while PDF opens in every browser's built-in viewer.

Best settings for DCR to PDF
There are no settings: camera white balance, sRGB colour and the full sensor resolution, up to 16,384 pixels a side.

About DCR and PDF files
What is a DCR file?
DCR is the raw format of Kodak's professional DCS cameras, which Kodak built on Nikon and Canon bodies, such as the DCS 760 and the DCS Pro 14n. Kodak stopped making them in 2005, so few programs besides raw developers still open the files.
What is a PDF file?
A PDF fixes the layout of every page so it looks the same on any device. Converting a PDF to an image renders each page to pixels; converting an image to PDF wraps it as a page.
DCR to PDF not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit, and raw files from high-resolution cameras can pass it. Switch the camera to its compressed raw setting, or develop very large files in a desktop raw editor.
- "This file is not really in DCR format." The converter checks every file before it runs anything, so a file of another format renamed to .dcr is refused. Choose the page for its real format.
- "The photo could not be read." The decoder on our server, LibRaw 0.20, knows cameras released up to about 2020. Raw files from newer models, and Canon CR3 and Sigma X3F files, may not open.
- The colours look flat. The photo is developed neutrally, without the contrast and styles a camera adds to its own JPGs. Adjust it in a photo editor.
Convert DCR to PDF from the command line
LibRaw and ImageMagick do the same on your own computer:
dcraw_emu -w -o 1 -q 3 -T input.dcr
magick input.dcr.tiff output.pdfConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
DCR to PDF converter FAQ
Will I lose quality converting DCR to PDF?
The PDF is 8 bits per channel, while the DCR held 12 or 14 bits of sensor data, so the extra room for adjusting exposure and colour is gone. Keep the DCR for editing.
Why is the PDF a different size from the DCR?
Usually smaller than the DCR, because JPEG compression is much more compact than raw sensor data.
Are my DCR files uploaded?
Yes, for this conversion. A faithful DCR to PDF conversion needs LibRaw and ImageMagick, two open-source tools, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the PDF as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several DCR files to PDF at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PDF file?
PDF opens in every browser's built-in viewer. PDF is common for documents, forms, invoices and print-ready files.
Is this DCR to PDF converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert DCR to PDF on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the PDF is saved to your Downloads folder.
