Byte Lens

ByteLens is a powerful hex editor and binary file inspector designed for developers, security researchers, and anyone who works with raw data. INSPECT ANY FILE Open any binary file and view its contents in a clean, structured hex dump. Every byte is displayed with its offset, hexadecimal value, and ASCII representation — all in a crisp monospaced layout. INTERPRET DATA INSTANTLY Select any byte or range of bytes and instantly see values interpreted as: - Unsigned and signed integers (8, 16, 32, 64-bit) - Floating point numbers (Float and Double) - Hexadecimal, decimal, and binary representations - Switch between little-endian and big-endian byte order SEARCH WITH PRECISION Find exactly what you're looking for with dual search modes. Search for ASCII text strings or hex byte patterns in flexible formats — with spaces, dashes, or continuous digits. Navigate between matches effortlessly. EDIT BYTES SAFELY Make targeted edits to any byte in a file. ByteLens uses a non-destructive patch layer so your original file stays untouched until you choose to save. Atomic file writes protect against data loss. BUILT FOR EVERY SCREEN ByteLens adapts intelligently to your device. On larger screens, the inspector panel sits alongside the hex view. On iPhone, it slides up as a convenient bottom sheet. Full keyboard shortcut support on iPad.
