Make a Wi-Fi QR, not a checkout code

Barcode generatorDraw a 1-D barcode — Code 128, EAN-13, or UPC — and download SVG in this tab. This does not register a GTIN with GS1. QR codes are a different tool.
Color palette generatorFive swatches to unblock a mock. Accessibility is a ratio on real type sizes, not a pretty ramp.
Fancy text generatorSocial-bio decoration, not typography. If a form must be searchable or accessible, stay in normal letters.
Invoice generatorBuild a simple line-item quote with a tax percentage you type, then print or save it from this tab. It is a freelance bill, not a VAT/GST tax invoice, not e-invoicing, and not bookkeeping software.
Password generatorMint a random charset password in this tab and glance at a strength estimate. It is not a passphrase wordlist, not a password manager, and we never see the string — you still have to save it somewhere that is not a sticky note.
QR code generatorEncode a URL, Wi-Fi login, vCard, or plain text into a static QR PNG in this tab. The data lives in the pixels, so the code does not expire and we cannot tell you who scanned it. This is not a payment QR.
QR code scannerDecode a QR from a screenshot or photo in this tab so you can read the URL before you visit it. This is not the phone’s live camera scanner and not a virus check.
UUID / ULID / NanoIDGenerate UUID v4, UUID v7, ULID, or NanoID in this tab. v7 and ULID leak creation time by design; v4 and NanoID do not. None of these is a password, and collisions are unlikely — not impossible — at huge scale.

Create a string, a code, or a dummy asset locally. Static QR is Wi-Fi, vCard, or URL — not a WeChat or Pix checkout.

You need a throwaway password, a v7 id for a row, a Wi-Fi QR for a guest network, or a 800×600 gray box for a mock. Generators here run in the tab. They are not Bitwarden, not Stripe, and not a tax invoice.

Honest product lines

Password generator is a random charset. Not Diceware. Not a vault.
UUID / ULID / NanoID — say which version you copied. v4 is random; v7 sorts by time.
QR code encodes a static payload (WIFI:…, URL, vCard). Do not chase payment-app checkout QR. Barcode is a different symbology.
Invoice generator is line items plus a tax %. Freelance quote, not a VAT e-invoice.
Lorem, placeholder image, favicon are mock assets.

Scan a screenshot of a QR on QR scanner — that is decode, not WeChat Scan.

What we generate — and refuse

Passwords are random charset, not Diceware, not a manager. QR is static Wi-Fi/vCard/URL, not a payment network. UUID offers v4, v7, ULID, NanoID. Invoice is line items plus a tax % — not a statutory e-invoice. Lorem and placeholder images are mocks.
