What files can I scan?

Any binary file up to 40 MB — images, PDFs, archives, media, firmware images, or disk dumps.

How deep does the scan go?

It finds every recognizable file signature embedded at the top level of your file — appended ZIPs, extra images, archives, and more. Nested archives are recovered whole so you can open them again.

Is this a malware scanner?

No. It carves out embedded files so you can inspect them. Always treat recovered files like anything you did not create.

Find hidden files in a binary

Bought an image, document, or download and suspect it is more than it looks? This page finds hidden files in a binary and gives you everything it can carve out.

How to find hidden files

Upload an image, PDF, firmware blob, archive, or any other file up to 40 MB.
Press Convert file.
Download the hidden files it recovered, plus a manifest describing each one.

What you get

Every embedded file binwalk can identify: ZIP and TAR archives, extra images, documents, compressed streams, certificates, executables, and more.
A manifest.json with the byte offset of each discovery, its detected type, its size, and where it was extracted.

A nested archive is pulled out as a complete file you can unpack again — nothing is silently dropped.

When this helps

You want to inspect a download or image for appended payloads before you trust it.
You are doing forensic or security analysis and need to carve recoverable files out of a blob.
You received a document that seems to carry more than its visible contents.

This is a carving tool, not a malware scanner. It surfaces what is embedded in the file without judging whether it is safe — only you choose whether to open it.
