What is MIME type "image/bpg"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

Better Portable Graphics (BPG) is an image format that uses modern compression techniques. The MIME type image/bpg signals that a file follows this format. It tells programs how to decode and display the image.

BPG was created to offer better image quality at smaller file sizes compared to older formats. This can be useful when you want high-quality images without heavy storage or bandwidth needs.

Efficient Compression: Cuts file sizes while keeping details sharp.
High Quality: Maintains fine details and supports rich colors.
Advanced Features: Offers support for alpha transparency and higher bit depths.
Web Use: Suitable for online images where speed and quality matter.

Files using this format come with the BPG extension. For more details on the format, check out the Better Portable Graphics homepage.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
