Discord Permissions Calculator

Discord permissions are stored as a single integer called a bitfield, where each bit represents one permission. This tool lets you toggle permissions visually and see the resulting number — or paste an existing number to instantly decode which permissions it represents.

Why bitfields? Discord serializes a variable-length permission integer as a decimal string. This calculator uses BigInt to keep the complete value. Each permission corresponds to a power of 2 (a specific bit position). Combining permissions is done with bitwise OR; checking a permission is done with bitwise AND. This is efficient and language-agnostic.

Common use cases for this calculator: - Setting up bot role permissions in Discord developer portal - Debugging "Missing Permissions" errors in bots - Generating the permissions integer for a bot invite URL (?permissions=NUMBER) - Understanding what permissions a role has from API responses - Building custom role templates for large servers

Key permissions explained: - Administrator (8) — grants all permissions, bypasses channel overrides - Manage Server (32) — change server name, region, integrations - Manage Roles (268435456) — create, edit, delete roles below bot's highest role - Moderate Members (1099511627776) — timeout members - Use Application Commands (2147483648) — use slash commands

Paste a non-negative decimal integer from a Discord API response, bot configuration or invite URL. Known flags are shown individually, and unrecognized bits are preserved. This is a role-level bitfield, not a calculation of effective channel access.
