DCR to PNG Converter
FileFlip converts DCR to PNG 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 DCR file to PNG?#
- 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 PNG 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 PNG file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting DCR to PNG lose quality?#
No. Converting DCR to PNG writes the data out again without discarding any of it, so nothing that was in the DCR file is lost on the way. What changes is the size of the file, not what is inside it.
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 PNG actually does to the file#
Converting DCR to PNG 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: DCR → PNG |
| 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 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 PNG file?#
A PNG file stores a raster image using lossless DEFLATE compression, which is why screenshots, logos, and graphics with flat colour or sharp edges use it instead of JPEG.
Use PNG for screenshots, logos, icons, and any graphic with flat colour or transparency, where exact pixel reproduction matters more than file size.
Convert PNG to JPEG or WebP when the image is a photograph and file size matters more than pixel-perfect reproduction, since a photographic PNG is typically several times larger than an equally sharp lossy file.
DCR to PNG 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.
Is PNG lossless?
Yes, PNG is always lossless. It compresses image data with the DEFLATE algorithm, the same family of compression used in ZIP files, so every pixel decodes back exactly as it was encoded. There is no lossy PNG mode, unlike JPEG.
