Open tool →Frequently Asked Questions
Does any design tool upload images or data to a server?
No. Image Resizer processes images entirely in your browser. Password Generator runs locally. No data is transmitted.
What colour formats does the converter support?
HEX (#0052ff), RGB (rgb(0, 82, 255)), and HSL (hsl(221, 100%, 50%)). All three formats are shown simultaneously.
What WCAG level should my website target?
At minimum WCAG AA — 4.5:1 contrast ratio for normal text. Public sector websites in the EU, UK, and US typically require AA compliance by law.
How strong is a 16-character password?
Using uppercase, lowercase, numbers, and symbols: ~10²⁸ possible combinations. At 100 trillion guesses per second, cracking it would take over 3 billion years.
