Binary file compare (xdelta3)

Comparison

Compares two binary files and produces a difference ("patch") file by means of xdelta3 tool.

This online tool lets you compare two binary files and see how they differ from each other . It also lets you patch one binary file with a «diff» file (usually having extension .diff or .patch) to generate a new («patched») version. 

This tool uses xdelta3 utility.
Note that this tool compares binary files – for text file comparison it's much more convenient to use a text diff tool. 

Max size of the input data is 10 MiB.

Wrappers are executed in sequence on shared data string. For example, to supply base64-encoded stream of GZIP-compressed data enter wrappers: base64, gzip and fill the data input with the base64 stream. 

If data is not entered information from other tabs (upload, by URL and direct) is used to replace data on this page. This lets you enter gzip as a wrapper here and upload a file using upload tab while leaving data on this page empty. 

Currently supported wrappers are: base64, bzip, cslashes, datauri, direct, ftp, ftps, gzip, hex2bin, http, https, qprintable, upload, url, urlencoding, zlib.
