Free Privacy Tools — Password, Email, Hash, QR | Freetempmail
Free browser tools for email validation, privacy checks, passwords, hashes, QR codes, Base64, URL encoding, JSON, and IP lookup without signup or remote uploads.
These utilities sit next to the temporary inbox product. Most run entirely in your browser: password generation, hashing, Base64/URL/JSON transforms, UUID and QR generation. IP detection needs a single network call and does not store results as a long-term profile. Use the email validator and privacy checker before you paste an address into a form. Nothing here requires an account. Open a tool, paste input, copy the result, leave.
QR Code Generator
Free online QR code generator: turn text or URLs into downloadable PNG images directly in your browser without uploads, built for links and codes.
UUID Generator
Free UUID v4 generator with batch mode and one-click copy. Runs locally for database keys, session IDs, test fixtures, and anonymous tokens.
Password Generator
Free strong password generator with custom length and character set controls. Computed in your browser with no upload, built for throwaway accounts.
Email Extractor
Free online email extractor: pull addresses from text, logs, or HTML in your browser. Runs locally with zero uploads and privacy warnings for bulk lists.
Email Validator
Free email format validator: check address syntax in one second. Convenient for form validation, developer debugging, and list hygiene using local rules.
Email Privacy Checker

Base64 Encoder / Decoder
Free Base64 encode/decode tool with UTF-8-safe handling in your browser. Useful for tokens, email attachment headers, and API payload debugging.
