二维码生成器

将当前 URL 或文本转换为可扫描的二维码。

QR codes are everywhere — menus, business cards, posters, product packaging, conference slides, documentation — yet generating one usually means visiting a third-party website, entering your URL, waiting for ads to load, and downloading a low-quality image. DevSuite Pro's QR Code Generator is built right into your browser. Open the tool and the QR code for the current page is already generated. Want a different URL? Just type it. Need to encode plain text, a Wi-Fi password, or a vCard? Enter it directly. The QR code updates in real-time as you type. Choose from three output sizes (128px for small icons, 256px for standard use, 512px for print-ready quality), preview the result, and download as a lossless PNG. No accounts, no watermarks, no ads.

核心功能

Auto-Generated from Current URL

The moment you open the tool, a QR code for the current page URL is already generated and ready. No need to copy-paste the URL — it's detected automatically from the active tab. Switch tabs and reopen to generate a code for a different page.

Custom URL or Text Input

Not limited to the current page. Enter any URL, plain text, email address, phone number, Wi-Fi credentials, or any string up to 4,296 characters. The QR code regenerates in real-time as you type, showing you the updated code instantly.

Multiple Output Sizes

Choose from three size presets: 128×128px (for small inline icons and favicons), 256×256px (standard size for web and presentations), or 512×512px (high-resolution for print materials, posters, and packaging). All sizes maintain crisp module edges.

Download as Lossless PNG

Export the QR code as a high-quality PNG image with a white background and clean module rendering. The file is named with the encoded content for easy identification in your downloads folder. No watermarks or branding added.

Real-Time Preview

The QR code updates live as you type or change the size. See exactly what the final output looks like before downloading. Test by scanning with your phone to verify it decodes correctly.

使用场景

Sharing Pages During Presentations
