Compare files hashes any two files with SHA-256 first; an identical hash means the byte content is identical. Only when the hashes differ, both files are 2 MB or smaller and the file headers do not look binary does it go on to decode the text intelligently and diff it line by line.

.patch.Two 5 MB binary files still get a SHA-256 comparison but no line-level text diff; two 100 KB text files produce a full patch.
The content is still reported as identical; file names are not part of the content hash.
Both files are read, hashed and diffed locally in the browser and are not uploaded.

Check two files for identical size, type and SHA-256; line-level diff for text files with .patch export
Once both are chosen, SHA-256 decides whether they match; text files also get a line-level diff
