Use practical browser-based utilities for formatting data, testing patterns, generating identifiers, inspecting tokens, and preparing assets. The SavvyToolz developer collection includes JSON formatting and validation, regular-expression testing, UUID and password generation, JWT inspection, hashing, Base64 conversion, text comparison, Markdown editing, QR codes, barcodes, Unix timestamps, and public IP lookup. Design and file helpers cover color values, image compression, background removal, placeholder text, and PDF page export. Tool pages explain supported formats and important limitations, and many sensitive transformations run locally in your browser. There is no account gate, so you can move from a debugging task to a usable result quickly.
