Are the generated passwords and tokens actually random?

Yes. The password and token generators use window.crypto.getRandomValues(), which is cryptographically secure: the same source browsers use for TLS.

Do the generated QR codes get stored anywhere?

No. QR codes are generated client-side and never sent to a server. You download them directly from your browser.

Can I customize the Lorem Ipsum generator?

Yes: you can control the number of paragraphs, sentences per paragraph, and starting word style. It also supports a few placeholder text variations beyond standard Latin.

What type of UUID does the generator output?

Version 4 UUIDs by default: random 128-bit identifiers in the standard xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx format. Suitable for database primary keys, file names, and session tokens.

Can the invoice generator produce a print-ready PDF?

Yes. Fill in your details and export to PDF directly from the tool. It produces a clean, professional-looking invoice layout with no watermarks.
