Online generators
Tools that make something from a few settings: a password from a set of rules, a gradient from two colours, a batch of test records from a schema.

About these tools
Generators produce something from a specification rather than transforming a file you already have: a QR code from a link, a barcode from a product number, a password from a set of rules, a batch of plausible test records from a schema.
Local generation matters most for the secret ones. A password produced by a server is a password that has been transmitted, whatever the site promises; here it is generated by your browser's own cryptographic random source and never leaves the tab. The same applies to the contents of any QR code you create.
Questions people ask
Will printable paper come out at the right size?
Yes, if you print at 100% (“Actual size”). The paper pages draw their lines in exact points — college ruling 9/32 inch apart, graph squares exactly 1/4 inch or 5 mm — on a page box the size of the real sheet. “Fit to page” shrinks everything by a few percent, so switch it off and measure a few squares with a ruler to check.
Is a password made in the browser actually random?
Yes. The password generator uses the browser's cryptographic random source (crypto.getRandomValues), and the password never leaves the tab. Length adds far more strength than symbols: a 16-character password from letters and digits beats a 10-character one with every symbol class.
Are the random name and number pickers fair?
They draw from the same cryptographic random source, so every entry has an equal chance on every draw. For giveaways where some entrants hold more tickets, use the weighted raffle draw instead.
