All the free tools
Every tool fastast serves, each on its own page. No account, no e-mail, nothing stored — open one, use it, close the tab.
Every tool here does one thing, on one page, and asks nothing of you: no account, no e-mail address, no cookie banner to dismiss before you can work. Type what you need, read the answer, close the tab. Nothing you enter is kept.
Each tool has its own address, so a link to one is a link to that tool alone. The list below is the whole set, and the search box filters it by name or by what a tool does.
Free vCard QR code: scanned, it adds your details to a phone's address book. Also an e-mail signature to paste and a printable sheet for a whole team.
Free WiFi QR code: guests scan it and their phone offers to join, no key to spell out. Print a guest card or a sheet for several networks. Nothing stored.
Free barcode generator: EAN-13, UPC-A, Code 128, ITF-14, DataMatrix, PDF417 and more, check digit worked out, a run of codes as a sheet of labels.
Free QR code generator for a link, phone number, e-mail, place or calendar event. Download as PNG or SVG, print a sheet, or read a code back.
