Binary & Hex Tools

Upload any file to view its raw binary contents as an interactive hex dump with side-by-side hex and ASCII column display. Search for byte patterns using hex notation (FF D8 FF) or ASCII text, navigate through pages of 1024 bytes, and inspect every byte. Supports files of any type and size -

Convert text to binary (0s and 1s) or decode binary to text with 8-bit UTF-8 and 16-bit UTF-16 representation modes. See a detailed character breakdown table showing binary, decimal, and hex values for each character. Supports swap direction, real-time conversion, and copy/download. All processing is local in your.

Compute Cyclic Redundancy Check (CRC) values for text strings or files using CRC-8, CRC-16, CRC-32, and CRC-64 with 18 polynomial standards including IEEE 802.3, MODBUS, Castagnoli, Kermit, XMODEM, ECMA-182, and more. View results in hex, decimal, and binary formats. Verify computed values against expected checksums.

Upload any file to count byte values (0-255) and view a complete frequency distribution. Calculates Shannon entropy to classify files as text, binary, compressed, or encrypted. Displays an interactive histogram, detailed byte statistics (mean, median, mode), and top/bottom byte frequency tables -

Upload any binary file and define a structure template with field types (uint8, uint16, uint32, uint64, int8, int16, int32, int64, float32, float64, string, hex, bytes, struct) at specific byte offsets. Includes 10 pre-built templates for BMP, PNG, JPEG, GIF, ELF64, WAV, ZIP, PDF, and WebP headers. Supports per-field.

Upload any file or paste text to detect Byte Order Mark (BOM) at the start. Shows the BOM hex sequence, interpreted encoding, and endianness. Supports UTF-8, UTF-16 (BE/LE), UTF-32 (BE/LE), UTF-7, SCSU, BOCU-1, and GB-18030. Interactive hex dump with highlighted BOM bytes and a complete BOM reference table - all.

Free online BOM (Byte Order Mark) Detector. Upload any file to detect BOM signatures for UTF-8, UTF-16, UTF-32, and other encodings. View hex dump with BOM bytes highlighted, encoding details, endianness, and cross-platform compatibility recommendations. 100% private browser-based processing - no signup required.

Free online File Chunk Analyzer. Upload any PNG, IFF (ILBM), WAV, or AVI file to analyze its internal chunk structure. Lists all chunks with type, offset, size, CRC validation (PNG), and format-specific descriptions. 100% private browser processing - no signup required.

Free online File Offsets Finder. Upload any file and jump to any byte offset in decimal, hex (0xNN), or percentage format. See each byte as hex, decimal, and ASCII with plain-English interpretation. Navigate byte by byte with context table. Supports any file type, 100% private browser-based processing. No signup.
