K25 Converter
FileFlip converts K25 files into 62 other formats entirely inside your browser, using ImageMagick, MuPDF and Pandoc compiled to WebAssembly. The K25 file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a K25 file?#
- Drop your K25 file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert K25 files online?#
Yes, because nothing is uploaded. FileFlip converts K25 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 is a K25 file?#
A K25 file holds the raw sensor dump written only by the Kodak DC25, a 1996 consumer digital camera and one of the first to save photos to a removable CompactFlash card.
K25 only comes up when opening images pulled from an original Kodak DC25 memory card; there is no reason to create one today.
Convert K25 to TIFF or PNG for long-term storage, since almost no current photo software recognizes the format directly.
The K25 file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
K25 questions people ask#
What camera made this K25 file?
A K25 file comes exclusively from the Kodak DC25, a consumer digital camera released in 1996. No other camera ever wrote this format.
What still opens a K25 file today?
K25 files open in raw converters built on the LibRaw library, such as RawTherapee and darktable, which still list the Kodak DC25 among their supported cameras. Kodak's own software for the camera is long unsupported.
Is K25 the same as other Kodak raw formats like DCR or KDC?
No. K25 is specific to the Kodak DC25, while DCR belongs to Kodak's professional DCS-series cameras and KDC belongs to later Kodak consumer models. The extensions come from the same manufacturer but are not interchangeable.
