Which MIME types are related to file extension ".mmr"?
The .mmr file extension is associated with 1 MIME types:
image/vnd.fujixerox.edmics-mmr.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .mmr Files
MMR files are compressed fax image files used to store scanned, monochrome documents. They are associated with the MIME type image/vnd.fujixerox.edmics-mmr.
These files use a Modified Modified READ compression algorithm that efficiently encodes binary (black and white) images, making them ideal for fax transmissions and scanned document storage.
- Main use: Archiving fax and scanned document data.
- Image type: Typically, bitonal (black and white) images.
- Software support: Some fax viewers, image converters, and scanning utilities like IrfanView or XnView may open these files.
They work well for users who need to quickly view or archive fax images without requiring full-color detail.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .mmr file used for?
An .mmr file is a compressed image format primarily used for storing fax transmissions and scanned documents. It utilizes the Modified Modified READ algorithm to efficiently compress monochrome (black and white) data, reducing file size for storage and transmission.
How do I open an .mmr file on Windows?
Standard Windows image viewers usually do not support raw MMR files. You will need third-party software such as IrfanView (with plugins installed), XnView, or specialized EDMICS viewing software to open and view these documents.
Can I convert an .mmr file to PDF or JPG?
Yes, you can convert .mmr files using image viewers like XnView or IrfanView. Open the file in the software and use the File > Save As or Export menu to save the document as a standard PDF, JPG, or TIFF file.
What is the MIME type for .mmr files?
The standard MIME type associated with these files is image/vnd.fujixerox.edmics-mmr. This identifier helps systems recognize the file as a vendor-specific image format used in Fuji Xerox EDMICS systems. You can learn more about image types at mime-type.com.
Why is my .mmr image only in black and white?
The MMR compression algorithm is designed specifically for bitonal images, meaning it only stores black and white pixels without grayscale or color data. This design is intentional to maximize compression efficiency for text documents and faxes.
Is an .mmr file the same as a TIFF file?
Not exactly, though they are closely related. A TIFF file acts as a container that often uses MMR compression internally to store images. A standalone .mmr file is typically a raw data stream of that compressed image without the standard TIFF file headers.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
