Begrensninger

Requires JavaScript. Extremely large inputs may slow the browser tab. Results depend on your browser APIs; there is no server-side processing quota because nothing is uploaded.

When to use

When you want a quick, free utility without creating an account or sending content to an online converter.

When not to use

When you need server-side integration, batch automation at scale, or certified compliance tooling.

Privacy note

Tool inputs are processed in your browser only. Theme, language and favorites may use localStorage; hosting may keep standard access logs (IP, UA, URL) without tool payloads.

FAQ（5）

Symbolic vs octal?

Toggle rwx bits or type 755-style modes—both stay in sync.

Sticky/setuid?

Advanced bits included when the UI exposes them.

Uploaded?

No.

Applies to remote files?

It only calculates modes—you still run chmod on the host.

Directories?
