Adobe encapsulated PostScript file magic bytes (.eps)
.eps file signature: C5 D0 D3 C6 | application/postscript
Category: Images
Encapsulated PostScript (EPS) is a graphics file format developed by Adobe and based on the PostScript page description language. It is used for vector illustrations, logos, layout exchange, and print production workflows, and is commonly supported by desktop publishing and illustration applications. As a legacy format, EPS may contain executable PostScript instructions, so files from untrusted sources should be opened with caution in software that properly restricts script execution.

Frequently Asked Questions
What is a .eps file?
A .eps file is an Adobe encapsulated PostScript file. Encapsulated PostScript (EPS) is a graphics file format developed by Adobe and based on the PostScript page description language. It is used for vector illustrations, logos, layout exchange, and print production workflows, and is commonly supported by desktop publishing and illustration applications. As a legacy format, EPS may contain executable PostScript instructions, so files from untrusted sources should be opened with caution in software that properly restricts script execution.
What are the magic bytes for .eps files?
The magic bytes for Adobe encapsulated PostScript file (.eps) files are C5 D0 D3 C6 at byte offset 0. These bytes identify the file format more reliably than the extension alone.
How do I validate a .eps file?
To validate a .eps file, read the first bytes of the file and compare them against the known magic bytes (C5 D0 D3 C6) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .eps files?
The primary MIME type for .eps files is application/postscript.
Is it safe to open .eps files?
Adobe encapsulated PostScript file (.eps) 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.
