Progwhiz Hex Editor

Progwhiz Hex Editor is a feature-rich Chrome extension designed for advanced hex file editing directly in your browser. It supports powerful search and replace operations in both text and hexadecimal formats, including sophisticated wildcard searches. Users can easily find and replace patterns such as partial words (e.g., "HEL?" or "HE?P") or hex sequences with unknown bytes (e.g., "55??AA") for precise editing tasks.

Notably, Progwhiz introduces support for 4-bit hex wildcards, enhancing flexibility by requiring two '??' symbols to represent one 8-bit unknown hex value. This capability sets it apart as a versatile tool for developers, firmware engineers, and tech professionals who require detailed manipulation of binary files. While the demo version is read-only, it provides a glimpse into its robust feature set that rivals powerful desktop hex editors.
