File Checksum FAQ
Is this checksum calculator free?
Yes, with no account and no limits.
Are my files uploaded?
No. They are read in your browser tab and never leave your device, so even large files are checked without waiting for an upload.
Which checksum files are read?
The sha256sum style (hash, two spaces, file name), the BSD style (SHA256 (file) = hash) and .md5 files.
How fast is it?
It depends on your device. All chosen algorithms are computed in one pass over the file.
