Random String Generator
Generate random strings instantly in your browser for test data, invite codes, temporary IDs, mock API keys, filenames, and developer workflows. Choose the length and character sets you want—such as lowercase letters, uppercase letters, numbers, or symbols—to create output that fits your use case. ToolMill runs fully client-side, so nothing you generate is uploaded to a server.

SHA-256 Hash Generator
Generate SHA-256 hashes in your browser for checksums, content verification, reproducible fingerprints, API testing, and debugging across systems. It is useful when comparing values, validating downloads, or confirming that text inputs produce the expected digest. ToolMill performs hashing locally for privacy; for password storage, use a dedicated password hashing algorithm such as Argon2, bcrypt, or scrypt instead of plain SHA-256.

UUID v4 Generator
Generate UUID v4 values instantly in your browser for database records, API requests, correlation IDs, log tracing, fixtures, and distributed systems. This tool is useful when you need quick unique identifiers during development, testing, or manual data entry without relying on a CLI or external service. ToolMill keeps generation local and does not send your data anywhere.
