Useful next steps
Choose two files
Select both local files. Their selection order determines the left and right byte streams.
Inspect changed regions
Each contiguous difference becomes an offset range. Extra bytes at the end also count as differences.
Export a precise report
Download CSV with decimal and hexadecimal starting offsets and JSON with the byte counts. Neither original file is modified.
