Hex File Viewer
Open any file to inspect it as a classic hex dump — offset, hex bytes and ASCII side by side — paged so even larger files stay fast. The file never leaves your device.
No file loaded. Page size: 512 bytes.
Hex dump will appear here.
How to use
- Choose any file from your device.
- Read each row: offset, 16 hex bytes, then the ASCII view.
- Use Previous and Next to page through the file.
Tips
- The left column is the byte position (offset), the middle is the raw data, the right shows readable text.
- Odd bytes at the very start of a file often reveal its real type (for example, PDFs start with “%PDF”).
- Dots in the text column are bytes with no printable character — that is normal for binary files.
Note: Non-printable bytes are shown as a dot in the ASCII column, exactly like classic hex editors. Nothing is uploaded — the file is read with the browser FileReader API.
