File Content ComparisonUser Guide
Read two local files piece by piece and check whether the complete byte contents are consistent; the same file name and file extension does not mean that the content is the same.
How to use
Import file A and file B separately.
Start the comparison and wait for a complete read. You can cancel it on the way.
Check whether they are exactly the same, size and difference position, and copy the complete result.
Formats and limits
Compare two files at a time, up to 100 MiB each.
This tool checks bytes, does not parse file semantics, and does not provide virus or source verification.
Output
Complete comparison report, the original file remains unchanged.
Frequently asked questions
The two documents look the same, so why are the results different?
Encoding, newlines, metadata, or compression may cause byte differences. This tool is based on complete file bytes.
