Hex Dump

Open any file - an image, executable, archive, database, or unknown blob - to see its bytes as hex with an ASCII column, offsets, and the detected file type.

About Hex Viewer

Open any file in your browser and read its raw bytes as a classic hex dump: offsets, hex pairs, and an ASCII column side by side. The viewer identifies the file type from its magic bytes, searches for text or hex patterns, and jumps to any offset, without uploading the file anywhere.

Key Features

Recognizes PNG, JPEG, PDF, ZIP, GZIP, ELF, PE, Mach-O, WebAssembly, SQLite, MP4 and more from their signature bytes
Search by text or hex pattern with match highlighting, plus jump-to-offset in decimal or 0x hex
8, 16, or 32 bytes per line, upper or lowercase hex, copy the visible page or download the full dump

Use Cases

Checking whether a download is really the format its extension claims, or has a corrupted header
Inspecting binary protocol captures, firmware images, save files, and serialized data during debugging
Seeing the exact UTF-8 bytes behind a string, including BOMs, zero-width characters, and emoji
