Multi-Mode Hex Viewer
View binary data in professional hex dump format with offset addresses, byte values color-coded by type (null, printable, control, high-byte), and synchronized ASCII panel.
View any .bin, .img, .rom, .dat or binary file in hex, ASCII, text and binary formats. 100% browser-based — your files never leave your device.

Everything you need to inspect, analyze, and understand any binary file — right in your browser, for free.
View binary data in professional hex dump format with offset addresses, byte values color-coded by type (null, printable, control, high-byte), and synchronized ASCII panel.
Search for specific hex byte sequences, ASCII strings, or plain text patterns within your binary file. All matches are highlighted instantly across the viewport.
Automatically detects file type from magic bytes, calculates entropy, byte frequency distribution, printable vs binary ratio, and identifies embedded strings.
All processing happens entirely in your browser using JavaScript. Your binary files are never uploaded to any server. Perfect for sensitive firmware, proprietary data, or confidential files.
Export the full hex dump as a .txt file for documentation, reporting, or sharing. Includes offset addresses, hex bytes, and ASCII representation in standard format.
Handles binary files up to 50MB smoothly. Large files are paginated in chunks of 4096 bytes so your browser stays fast and responsive regardless of file size.
Switch between Hex dump, ASCII view, printable Text strings extraction, raw Binary bit view, and comprehensive File Info panel — all with instant rendering.
Fully responsive layout. Use drag-and-drop on desktop or file browse on mobile. The hex viewer adapts beautifully across all screen sizes without horizontal scroll.
No plugins, no extensions, no registration required. Works on any modern browser on Windows, macOS, Linux, iOS, and Android. Bookmark and use anytime.
No technical expertise needed. Inspect any binary file in seconds.
Drag and drop your binary file (.bin, .img, .rom, .dat, .exe, or any binary format) onto the drop zone, or click Browse Files to select from your device.
Select Hex, ASCII, Text, Binary, or File Info view from the tabs. Switch instantly between modes. Use the search bar to find specific byte patterns or strings.
Inspect file structure, magic bytes, entropy, and byte distribution. Copy the output to clipboard or export a complete hex dump as a text file for offline use.
All analysis is done entirely in your browser. Close the tab when done — no traces are left on any server. Safe for firmware, ROM dumps, and sensitive binary data.
Everything you need to know about opening and viewing binary files online.
Open and analyze any file format — from Excel and CSV to PDF and DOCX — all online, free, and private.
A binary file viewer (also called a hex editor or hex viewer) is a tool that lets you inspect the raw bytes of any file. Unlike text editors that show only human-readable characters, a binary viewer displays every byte in hexadecimal notation, giving you full visibility into the underlying structure of firmware, executables, disc images, and other binary data files.
Engineers, reverse engineers, security researchers, embedded developers, and curious power users open binary files to: verify file integrity using magic bytes, debug firmware issues, examine file structure and offsets, extract embedded strings or resources, detect compression or encryption, and compare binary versions of files.
A hex dump presents binary data in three columns: the offset (position from the start of the file), the hex bytes (16 bytes per row in hexadecimal), and the ASCII representation (printable characters shown, non-printable shown as dots). This format is the industry standard used by tools like xxd, hexdump, HxD, and 010 Editor. Our online tool replicates this format accurately so results are familiar to any developer or analyst.
