Frequently asked questions
- Are these QR tools free?
- Yes — free, no signup, no watermark, and no daily limit.
- Are my QR codes uploaded anywhere?
- No. Every QR code is generated entirely in your browser — your password, location or contact info never leaves your device.
- Will the QR codes work forever?
- Yes. The codes are static — they encode the data directly, so they don't depend on our servers and won't expire.
- What error correction level do you use?
- Medium (~15%) by default — a good balance between density and resilience. The QR text/URL tool lets you raise it to High (~30%) when you want a logo overlay.
- Which barcode formats do you support?
- Code-128, EAN-13, EAN-8, UPC-A and Code-39 via JsBarcode. The reader uses ZXing and recognises most 1D and 2D formats.
