About
Chmod Calculator builds Unix file permissions with a visual read/write/execute toggle grid for owner, group, and others, showing the resulting octal value like 755, symbolic notation like rwxr-xr-x, and the actual chmod command to run — useful when you know what access you want but don't want to do the binary-to-octal math by hand. Runs entirely in your browser.
