PEA (.pea)
.pea file signature | application/octet-stream
PEA (Pack, Encrypt, Authenticate) is an open archive file format developed by Giorgio Tani and maintained as part of the PeaZip project. It is used for compressing files, grouping directories, and applying optional encryption and integrity checks for backups and file exchange. The format is less widely supported than common archive types, so compatibility may depend on dedicated software; files from untrusted sources should still be scanned before extraction.

Frequently Asked Questions
What is a .pea file?
A .pea file is identified by the magic bytes 78 56 34 at byte offset 0. PEA (Pack, Encrypt, Authenticate) is an open archive file format developed by Giorgio Tani and maintained as part of the PeaZip project. It is used for compressing files, grouping directories, and applying optional encryption and integrity checks for backups and file exchange. The format is less widely supported than common archive types, so compatibility may depend on dedicated software; files from untrusted sources should still be scanned before extraction.
What are the magic bytes for .pea files?
The magic bytes for PEA files are 78 56 34 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .pea file?
To validate a .pea file, read the first bytes of the file and compare them against the known magic bytes (78 56 34) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .pea files?
There is no officially registered MIME type for .pea files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .pea files?
PEA (.pea) 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.
