.SRF File Extension Reference
The .SRF format is a specialized digital image specification utilizing raster or vector encoding for graphical assets. It maintains structured color palettes, coordinate bounding boxes, and compressed pixel arrays. Files with the .SRF extension are categorized under Images and are widely utilized in modern computing environments for storing, rendering, and exchanging structured data. By verifying the header signature (49 49 2A 00) using forensic byte inspection tools, users can authenticate file integrity and rule out disguised executable payloads.

What is a .SRF File? (Technical Definition & Architecture)
The .SRF format is a specialized digital image specification utilizing raster or vector encoding for graphical assets. It maintains structured color palettes, coordinate bounding boxes, and compressed pixel arrays. Files with the .SRF extension are categorized under Images and are widely utilized in modern computing environments for storing, rendering, and exchanging structured data. By verifying the header signature (49 49 2A 00) using forensic byte inspection tools, users can authenticate file integrity and rule out disguised executable payloads.
Optimized raster or vector algorithms designed for digital rendering and photo encoding.
Encapsulates color matrices preserving natural contrast and tonal distribution.
Enables layered compositing, icon cutouts, and transparent website assets.
SRF Binary Structure & Header Specifications
The .SRF format organizes data into validated sequential or hierarchical byte structures. Inspecting the header offset reveals the magic byte sequence 49 49 2A 00.
- File Signature (Magic Bytes): 49 49 2A 00
- MIME Content-Type: image/x-sony-srf
- Payload Structure: Optimized data stream with metadata headers and checksum records.
- Safety Classification: Low Risk – TIFF tag structure storing raw Bayer matrix pixels Files ending in .SRF should always be inspected for valid magic bytes to verify they match legitimate Images specifications.

.SRF MIME Types & HTTP Server Headers
When serving .srf files over HTTP or configuring REST APIs, web servers must send the official IANA registered Content-Type headers:
| MIME Type Identifier | Standard Usage | File Extensions | Copy |
|---|---|---|---|
| image/x-sony-srf | Standard official MIME type for .srf files | .srf |
# Nginx mime.types
types {
image/x-sony-srf srf;
}
# Apache .htaccess
AddType image/x-sony-srf .srf.SRF Magic Bytes & Hex File Signatures
In digital forensics and file signature analysis, authentic .srf files begin with a standardized magic byte sequence at byte offset 0x00 to verify file integrity and prevent extension spoofing:
