About Online Tools
Online Tools is a collection of browser-based utilities for text and data work. The homepage groups them into hashing, cryptography, compression, encoding, formatting, conversion, and generator tools. Users can calculate hashes such as SHA-2, SHA-3, and BLAKE, apply encryption algorithms such as AES and ChaCha20, compress or archive files in formats such as GZIP and ZIP, and encode or decode values such as Base64 and URL strings. It also includes JSON and XML formatting, case conversion, UUID, password, and QR code generators.
The source does not say whether data is processed locally in the browser or sent to a server, and it does not describe the security of the cryptographic tools. Users handling sensitive data should check how each tool works before relying on it. Pricing is not stated in the source.
