RMF File Format (.rmf)
An RMF file with image content is handled by treating its bytes as raw camera sensor data, since ImageMagick routes the .rmf extension to its DNG decoder rather than to a decoder built for an independently documented RMF image format.
RMF at a glance#

| File extension | .rmf |
| Category | Image Files |
| Compression | Varies from file to file |
| FileFlip support | FileFlip reads this format but does not write it |
Strengths and limitations of RMF#
What RMF does well
- Decodes through the same DNG raw-image pipeline ImageMagick already uses for camera raw files, so no separate decoder had to be written for it
Where RMF falls short
- No public specification for an RMF image format could be found, so there's no way to confirm what a given .rmf file's bytes actually mean
- The .rmf extension is also used for at least three unrelated formats elsewhere: Valve's Hammer Rich Map Format for level editing, Beatnik's Rich Music Format for MIDI audio, and Adobe's rights-management license files, none of which are images
- A file will only open successfully if its bytes happen to match the raw sensor layout the DNG decoder expects; most .rmf files will not
There's no established reason to create a file as RMF; treat one only as raw camera sensor data if that's confirmed to be its actual source.
Convert an .rmf file to DNG or JPG as soon as it needs to open outside of ImageMagick's raw-image pipeline, since almost nothing else recognizes the extension as an image.
How to open a .rmf file#
A .rmf file opens in the programs below, grouped by the platform you are on. If you would rather not install anything, FileFlip converts RMF into a format your machine already opens, and it does it in the browser tab rather than on a server.
| Platform | Programs that open it |
|---|---|
| Windows | ImageMagick |
| macOS | ImageMagick |
| Linux | ImageMagick |
| Web | FileFlip |
RMF questions people ask#
What is an RMF file?
As an image, an RMF file is data that ImageMagick decodes using its DNG raw-camera decoder, because no independently published RMF image format specification exists. The .rmf extension is also used, unrelatedly, for Valve level-editor files, Beatnik MIDI music files and Adobe rights-management licenses, so a file's actual contents depend entirely on what produced it.
What program opens RMF image files?
ImageMagick and libraries built on it will attempt to open an RMF file as raw camera sensor data through the same decoder used for DNG files. Because there's no confirmed RMF image specification, there's no other software known to open it as an image.
Why won't my RMF file open as an image?
Unlike JPG or PNG, .rmf is not a fixed, documented image format, so a decoder only succeeds if the file's bytes happen to match the raw sensor layout ImageMagick's DNG decoder expects. A file with this extension might just as easily be a Hammer level file, a MIDI-based audio file, or a rights-management license, none of which are images at all.

FileFlip does not write .rmf files, so nothing on the site converts into this format. It works as a source only.
Every conversion runs inside your browser. The file is read from your disk, the work happens on your own machine, and nothing is uploaded. How FileFlip works names the engine behind each family and how to verify that for yourself.
