Free means free
Every tool here works without an account and without a trial clock. Results are yours to download, copy and share.
Private by default
Tools run in your browser. What you type stays on your device, except the link preview checker, which has to fetch the public page you ask it to check.
When to use VISU
Static results cannot change after you share them. A VISU account adds dynamic QR codes, link pages and campaigns you can edit and measure.
