About .arw Files
ARW files are raw image files created by Sony cameras. They store unprocessed sensor data for optimum editing flexibility.
They retain high detail and dynamic range. This file type needs conversion in image processing software to produce finished photos.
- Purpose: Preserve maximum image information for post-processing.
- MIME Types: Identified as image/x-raw-sony and image/x-sony-arw, among others in the raw camera family.
- Usage: Preferred in professional photography and by enthusiasts for its superior quality compared with compressed formats like JPEG.
- Software: Compatible with apps like Adobe Photoshop, Adobe Lightroom, Sony Imaging Edge, and various raw conversion tools.
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
How do I open an ARW file on Windows or Mac?
You can open ARW files using the default Microsoft Photos app (requires the Raw Image Extension) on Windows or Apple Preview on macOS. For advanced editing, professional software like Adobe Lightroom, Capture One, or Sony's free Imaging Edge Desktop is recommended.
How can I convert ARW files to JPG?
To convert an ARW file, open it in an image editor like Adobe Photoshop or IrfanView and select File > Export or Save As to choose JPG format. Alternatively, you can use online conversion tools, though these may have file size limits.
Why do my ARW photos look flatter or duller than JPEGs?
ARW files are raw sensor data and do not have in-camera processing (like saturation or contrast adjustments) applied to them. They are designed to be "developed" in post-processing software, which gives you greater control over the final look compared to a pre-processed JPEG.
Why can't I see ARW thumbnails in Windows Explorer?
If your thumbnails are missing, you likely need to install the Raw Image Extension from the Microsoft Store. This codec allows the operating system to decode and display previews for raw formats like image/x-sony-arw.
What is the correct MIME type for ARW files?
When configuring servers or applications, the specific MIME type is often image/x-sony-arw or image/x-raw-sony. For a broader list of raw image media types, you can consult mime-type.com.
Can I edit ARW files on a mobile phone?
Yes, you can edit ARW files on iOS or Android using apps like Adobe Lightroom Mobile or Snapseed. However, default gallery apps may not support viewing raw files without these third-party tools.
Is an ARW file better than a JPEG?
Yes, for editing purposes. ARW files retain all the data captured by the camera sensor, allowing for significant recovery of shadows and highlights. JPEGs are compressed and discard much of this data, limiting editing flexibility.
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.
