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 — no signup, no upload.
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 a downloadable PNG in your browser. No upload, no signup — ideal for links and one-time codes.
UUID Generator
Free UUID v4 generator with batch mode and one-click copy. Runs locally — great for database keys, session IDs, test fixtures, and anonymous tokens.
Password Generator
Free strong password generator with length and character-set controls. Computed in your browser with no upload — ideal with temporary email signups.
Email Extractor
Free online email extractor: pull addresses from text, logs, or HTML in your browser. Local-only — no upload, with a privacy warning for bulk lists.
Email Validator
Free email format validator: check address syntax in one second. Handy for form validation, developer debugging, and list hygiene — local rules only.
Email Privacy Checker
Free email privacy checker: detect aliases, role prefixes, and disposable-domain signals. Local rule checks only — your email never leaves the browser.
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.
URL Encoder / Decoder
Free URL percent-encode and decode with zero network requests. Ideal for query strings, callbacks, redirects, and temporary-email verification links.
JSON Formatter
Free online JSON formatter and validator: pretty-print, minify, and check syntax locally — perfect for API debugging and config cleanup.
Hash Generator
Free hash generator for MD5, SHA-1, SHA-256, and SHA-512. Nothing is uploaded — useful for integrity checks and developer debugging.
IP Detector
Free public IP and approximate geolocation lookup. One query, no long-term retention — handy for VPN, proxy, and egress checks.
