What is Puzil.Net (PuzilNet)?

Puzil.Net is a free collection of browser tools that needs no install and no account: JSON validation, Base64, passphrase encryption, QR codes, character counting, world time zones, a color picker, images to PDF, and Korean real estate and loan calculators.

Almost every tool runs entirely in your browser, and preferences such as menu order, language, and theme are stored only in this browser — so you can work with personal files without uploading them.
