About this tool
Convert text, URLs, contacts, Wi-Fi credentials, and more into high-quality QR codes with real-time preview and customization.
Text to QR Code encodes plain text, a URL, an email, a phone number, an SMS, a WhatsApp link, Wi-Fi credentials, a vCard contact, a geo location or a calendar event into a scannable QR code using the standard payload formats each phone camera already understands. Pick the payload type, fill the fields, and the code redraws live as you type. You control colour, size from 150 to 512 px, quiet-zone margin, error-correction level L/M/Q/H and an optional centre logo, then export PNG, SVG or JPEG.
Open Text to QR Code on AltFTool — it loads instantly in your browser.
Pick a payload from the ten type tabs — Text, URL, Email, Phone, SMS, WhatsApp, Wi-Fi, Contact, Location or Event — and fill in its fields; the code redraws as you type.
Under 'Customize QR Code', set the colours, a Size from Small (150) to Print (512), the Margin, Error Correction from Low (7%) to High (30%), and optionally Upload a centre logo.
Choose PNG, SVG or JPEG in the Format selector and press 'Download QR Code' — the file saves as qr-code.png, qr-code.svg or qr-code.jpeg, with Copy, Print and Share below.
Text, URL, mailto with subject and body, tel, SMS, wa.me, WIFI, vCard, geo and iCalendar are each built to their own spec rather than pasted as raw text.
L, M, Q and H recover roughly 7%, 15%, 25% and 30% of a damaged or logo-covered code, so you can raise the level before adding a centre logo.
Export SVG for signage that scales without pixel edges, or PNG/JPEG at up to 512 px, with a transparent-background option for overlaying on artwork.
Use H, which recovers about 30% of the code. The logo here covers roughly 18% of the code's width with the modules beneath it excavated, so levels L (7%) and M (15%) can leave too little redundancy to scan reliably; test the printed code before committing to a run.
Choose the Wi-Fi type and enter the SSID, encryption (WPA, WEP or none) and password. The tool writes the standard WIFI:S:<ssid>;T:<type>;P:<password>;; payload that iOS and Android cameras recognise natively — no app needed. Anyone who can photograph the code can read the password, so keep it off public-facing walls.
Most failures come from too little contrast, too small a print size, or no quiet zone. Keep a dark foreground on a light background, keep the margin at 4 modules or more rather than 0, and size the print so the code is at least about 2 cm square at normal scanning distance — long payloads such as vCards make a denser grid that needs more physical area.
Download SVG for anything printed and PNG for anything on screen. SVG stays sharp at any size because it stores the modules as shapes, while PNG at the 512 px Print setting is ample for web, slides and small labels; JPEG is offered for legacy workflows but its compression can soften module edges.
