Étapes & astuces (hex brut)

Utilisation

  1. Always work from a copy; use “Backup original” before any edit.
  2. Upload any file. The grid shows offset, 16 hex bytes per row, and ASCII. Click a byte to select it and read LE integers/floats in the inspector.
  3. Change bytes with the small hex input (00–FF) and Apply, or use diff to compare against the original buffer.
  4. Download writes the modified bytes with the same filename and MIME type as the upload.

Limites

  • No format validation is performed — suitable for unknown binaries, proprietary formats, or manual patch experiments.
  • Large files only virtualize rows on screen; very huge files may still stress the browser — keep backups.
  • Inspector values assume little-endian and may be meaningless if alignment is wrong — verify against known offsets for your game.
  • Prefer the JSON, Base64, or GVAS pages when you already know the file matches those patterns.
