Comparing files

Use a checksum from a trusted source. Matching hashes show that file bytes match the expected digest; they do not establish that a file is safe. This tool reads the whole file into memory and limits input to 100 MiB. If your browser blocks hashing from a local file, use HTTPS or localhost.
