Binary Hex Editor

About This Tool

This tool provides a binary hex editor that enables byte-level viewing and editing of arbitrary files. It presents raw data in hex and ASCII views, supports direct byte replacement, and allows insertion or deletion of data blocks. Users perform precise edits without converting to higher-level representations, preserving data integrity for downstream processes such as firmware modifications, data recovery, and reverse engineering.
For workflow, the editor loads the target file into memory, offers endianness and word-size interpretation, and exposes navigation by address, offset, or search results. Changes are staged and can be reviewed before saving, with optional checksum recalculation to maintain consistency in many file formats.
Audience includes software developers, firmware engineers, digital forensics professionals, and security researchers who need deterministic byte-level control. The tool differentiates itself by focusing on low-level data manipulation rather than text-only editing, supporting large files, and exposing rigorous input validation and reversible edits to minimize data corruption risks.
Key features include hex/ASCII views, search and patch capabilities, region selection, endianness controls, and export of modified files or patch manifests. Typical use cases are patching configuration bytes, repairing corrupted sectors, or diffing two binaries at the byte level to identify intentional changes.
