SVGZ (.svgz)
.svgz file signature | image/svg+xml
SVGZ is a compressed Scalable Vector Graphics file format standardized by the World Wide Web Consortium (W3C) as part of the SVG specification. It is used for web graphics, icons, illustrations, logos, and other vector images that need smaller file sizes while remaining scalable in browsers and vector-editing applications. SVGZ files are generally safe to open, although, as with SVG, they may contain scripts, links, or external resources, so files from untrusted sources should be handled with standard caution.

Frequently Asked Questions
What is a .svgz file?
A .svgz file is identified by the magic bytes 3C 73 76 67 at byte offset 0. SVGZ is a compressed Scalable Vector Graphics file format standardized by the World Wide Web Consortium (W3C) as part of the SVG specification. It is used for web graphics, icons, illustrations, logos, and other vector images that need smaller file sizes while remaining scalable in browsers and vector-editing applications. SVGZ files are generally safe to open, although, as with SVG, they may contain scripts, links, or external resources, so files from untrusted sources should be handled with standard caution.
What are the magic bytes for .svgz files?
The magic bytes for SVGZ files are 3C 73 76 67 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .svgz file?
To validate a .svgz file, read the first bytes of the file and compare them against the known magic bytes (3C 73 76 67) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .svgz files?
The primary MIME type for .svgz files is image/svg+xml.
Is it safe to open .svgz files?
SVGZ (.svgz) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
