Frequently Asked Questions
Are the generators free?+
Yes, all 5 generators are free with unlimited use. UUIDs, QR codes, lorem ipsum, favicons, and mock data are produced locally in your browser.
Can I customize what the generators produce?+
Yes. The UUID generator supports v4 and v7, the mock data generator produces realistic typed fields, and the QR generator lets you choose size, colors, and error-correction level.
Are generated UUIDs truly random?+
The UUID generator uses cryptographically secure randomness from the Web Crypto API, so every identifier is unique and unbiased.
Do I need an account to generate output?+
No. All generators work instantly on the page with a single copy or download action — no signup and no API keys.
