Toggle read, write, and execute checkboxes for owner, group, and others and see the numeric chmod value update in real time. Or type a number and see the permission breakdown.

It sets Unix file permissions — who can read, write, and execute a file. The three digits represent owner, group, and others.
Owner can read+write+execute. Group and others can read+execute but not write. Standard for web server directories.
The calculator shows both octal (755) and symbolic (rwxr-xr-x) formats side by side. Toggle checkboxes to see both update.
