Hex Viewer
View file contents in hex dump format with search, offset navigation, and virtual scrolling
What is a hex viewer?
A hex viewer displays file contents in hexadecimal format, showing each byte as a two-digit hex number alongside its ASCII representation. It is essential for inspecting binary files, debugging, and data analysis.
How do I search for specific bytes in a hex viewer?
Enter a hex string (e.g., "4D5A") or ASCII text in the search box. The viewer will highlight all matching positions and allow you to navigate between matches.
Can I view very large files?
Yes, this hex viewer on www.localtoolz.com uses virtual scrolling to efficiently handle large files. Only the visible rows are rendered, so even files over 1GB can be viewed smoothly.
What is the offset column in a hex dump?
The offset column shows the byte position (in hexadecimal) of the first byte in each row. It helps you quickly locate specific positions within the file.
Is my file data safe?
Yes, all processing happens locally in your browser. Your files are never uploaded to any server. This tool runs entirely on www.localtoolz.com using client-side JavaScript.
