Hex Editor

Fhex – full-featured hex editor

Fhex aims to be a lightweight yet full-featured hex editor. This project is based on qhexedit2, capstone and keystone engines.

This is cross-platform software which runs under Linux, macOS and Windows.

Fhex is published under an open source license.

Features include:

  • Chunks loader – Used to load only a portion of large files without exhaust the memory (use alt + left/right arrows to move among chunks). Please note that in chunk mode, all the operations (e.g. search) applies only to the current chunk except for file save (the entire file is saved). However, each time you edit a chunk, save it before to move to another chunk, otherwise you will lose your changes.
  • Search and replace (UTF-8, HEX, regex, reverse search supported).
  • Colored output (white spaces, ASCII characters, 0xFF, UTF-8 and NULL bytes have different colors).
  • Interpret selected bytes as integer, long, unsigned long.
  • Copy & Paste.
  • Copy selected Unicode characters.
  • Zeroing all the selected bytes.
  • Undo & Redo.
  • Drag & Drop to diff two files.
  • Overwrite the same file or create a new one.
  • Goto offset.
  • Insert mode supported in order to insert new bytes instead to overwrite the existing one.
  • Create new instances.
  • Basic text viewer for the selected text.
  • Reload the current file.
  • Compare two different files at byte level.
  • Browsable Binary Chart.
  • Hex – Dec number converter.
  • Hex String escaper (e.g from 010203 to \x01\x02\x03).
  • Pattern Matching Engine.
  • Disassembler based on Capstone Engine.
  • Assembler based on Keystone Engine.
  • Zoom-Out/Zoom-In bytes view.
  • Shortcuts for all these features
