What is a QR code generator?

A QR code generator is a free online tool that converts text, URLs, contact information, WiFi credentials, and other data into a scannable QR code image. When someone scans the QR code with their smartphone camera or a QR code scanner app, the encoded information is instantly decoded and the phone performs the appropriate action — opening a website, connecting to WiFi, saving a contact, or sending a message. Our free QR code generator creates high-quality QR codes in PNG and SVG formats with custom colors and logo support.

How do I create a QR code for a website URL?

To create a QR code for a website URL: 1) Select URL from the QR type tabs above. 2) Paste your website URL in the input field. 3) The QR code generates live as you type. 4) Optionally customize the foreground color, background color, or add a logo. 5) Click Download PNG or Download SVG to save your QR code. Our free QR code generator for URL creates high-resolution codes that work with all smartphones.

How do I generate a WiFi QR code?

To generate a WiFi QR code: 1) Select WiFi from the QR type tabs. 2) Enter your WiFi network name (SSID). 3) Enter your WiFi password. 4) Select the security type (WPA/WPA2, WEP, or Open). 5) The QR code generates automatically. 6) Download and print it or display it on your screen. When scanned, the phone will automatically connect to your WiFi network without manually typing the password. Our WiFi QR code generator is completely free.

Is this QR code generator free?

Yes, our QR code generator is completely and permanently free. Our tool is 100% free forever with no hidden fees, no login required, and QR codes that never expire. There is no account, no login, no subscription, no credit card, and no usage limits. You can create unlimited QR codes for any purpose.

Can I create a QR code with a logo?

Yes, our QR code generator with logo support lets you upload any PNG, JPG, or SVG image to embed in the center of your QR code. The logo is automatically sized to fit within the QR code without compromising scannability. For best results, use a square logo image with a transparent or white background. QR codes with logos have higher error correction built in to ensure they remain scannable even with the logo overlay.

What QR code types can I create?

Our free QR code generator supports 8 types: URL (website links), WiFi (network credentials for instant connection), vCard (contact information saved to phone), Email (pre-filled email compose), Phone (click to call), SMS (pre-filled text message), and Plain Text (any text message). Each type is optimized for its specific use case with the appropriate fields and formatting.

What is the difference between PNG and SVG QR codes?

PNG QR codes are raster images with a fixed pixel resolution — ideal for digital use like websites, emails, social media, and PowerPoint presentations. SVG QR codes are vector graphics that scale to any size without losing quality — ideal for print materials like business cards, posters, banners, and packaging where you need high-resolution output. Our free QR code generator lets you download in both formats at no cost.

Do QR codes generated here expire?

No, QR codes generated with our free tool never expire. Our QR codes are static, meaning all the data is encoded directly in the QR code image itself — there is no server or subscription keeping them active. Unlike companies that create dynamic QR codes tied to their servers (which expire when you stop paying), our QR codes work forever as long as the content they point to (like a website) remains available.

How do I create a vCard QR code for contacts?

To create a vCard QR code: 1) Select vCard from the QR type tabs. 2) Fill in the contact fields — name, phone, email, company, and website. 3) The QR code generates automatically. 4) Download it and add to your business card or email signature. When scanned, the recipient's phone will prompt them to save the contact information directly to their address book. This is the most efficient digital business card replacement.

Can I customize QR code colors?

Yes, our custom QR code generator lets you change both the foreground color (the dark dots) and background color (the light areas) to match your brand. Click the color pickers to choose any color. Important: always ensure there is sufficient contrast between the foreground and background colors — low contrast QR codes may not scan reliably. Avoid inverted colors (light dots on dark background) as many QR scanners do not support this.

What is the best QR code size for printing?

For reliable scanning, QR codes should be printed at a minimum size of 2x2 cm (about 0.8 inches square). For business cards, 2.5x2.5 cm works well. For posters or banners, 5x5 cm or larger is recommended. Our QR code generator produces high-resolution outputs — use the SVG format for print to ensure perfect quality at any size. The scanning distance should be approximately 10 times the QR code size.

Does this QR code generator work on mobile?

Yes, our free QR code generator is fully responsive and works on all devices including iPhones, Android phones, tablets, and desktop computers. You can create, customize, and download QR codes directly from your smartphone. The live preview updates as you type on mobile keyboards, and the download buttons save the QR code directly to your device gallery.

What is error correction in QR codes?

QR code error correction allows the code to be read even when partially damaged, dirty, or obscured — such as when a logo is placed in the center. There are 4 levels: L (7% recovery), M (15%), Q (25%), and H (30%). Our QR code generator uses Level H when a logo is added and Level M for standard codes, providing a good balance between data capacity and damage tolerance. Higher error correction means slightly larger QR code patterns.

Why should I use AgeCalcAI QR Code Generator instead of some paid QR tools?

Our free QR code generator is better than some paid QR tools and similar competitors for several key reasons: our QR codes never expire (competitorsome paid tools require a monthly subscription to keep QR codes active), no login or account ever required, all generation happens in your browser with complete privacy, SVG + PNG formats both free, 8 QR types supported, custom colors and logo embedding included free, and no paid subscription requirements after the free trial period ends.

What file format should I use — PNG or SVG?

Use PNG for digital use such as websites, emails, social media posts, and presentations. Use SVG for print materials such as business cards, posters, banners, and product packaging — SVG is a vector format that scales to any size without losing quality. Both PNG and SVG downloads are completely free in our QR code generator. For most print purposes, SVG is the recommended format as it produces sharp results at any resolution.
