Choose two files to compare locally. Review changed byte offsets and values without decoding either format.
Choose two local files (50 MB each).
A QUICK WALKTHROUGH
How to use this tool
- Choose two files within the 50 MB per-file limit.
- Compare their bytes in your browser.
- Review the first 1,000 differing offsets and hexadecimal values.
Local comparison
Files stay in this browser and are not uploaded.
Limits
Each file is limited to 50 MB; at most 1,000 differing rows are displayed.
Raw byte offsets
Offsets start at zero. Values are shown in hexadecimal; this tool does not interpret file formats.
