QR Code Generator
Enter some content to generate your QR code.
Processing happens locally on your device. Nothing is uploaded.
What Is This Tool?
QR Code Generator is a free, browser-based tool that turns any text or link into a scannable QR code. You type or paste your content, adjust the size, colors, margin and error tolerance, and download the result as a PNG image or a vector SVG file. Everything runs locally in your browser — no account, no upload, no watermark.
QR codes have become the universal bridge between print and digital: a poster, business card, menu or product package can send people straight to a link with one camera scan. This tool exists to make creating those codes instant and private, without forcing you through a sign-up wall or a paid "pro" tier just to download your own code.
Why Use This Tool?
Many online QR generators look free until you finish designing and hit a paywall, or they quietly route your link through their own redirect domain — which means your printed codes break the day their service shuts down or starts charging. Codes made with this tool encode your content directly, with no middleman, so they keep working forever.
Control matters too. A QR code that goes on a dark flyer needs different colors than one on a white receipt. Error tolerance lets you place a logo in the middle of the code or print it small on packaging without losing scannability. And because generation happens on your device, sensitive content — a private link, a Wi-Fi password, an internal URL — never travels across the internet just to become a QR code.
How It Works
The tool uses a standards-compliant QR encoder that runs entirely in your browser. When you enter content, the encoder analyzes its length and character set, packs it into the most efficient QR encoding mode, adds the level of error-correction redundancy you selected, and lays the modules out on the grid with all required alignment and timing patterns.
The result is rendered as a crisp image at your chosen pixel size for PNG downloads, or as resolution-independent vector paths for SVG downloads — which is what you want for print, since an SVG QR code stays sharp at any physical size. Color choices are applied to the foreground modules and the background, so you can match your brand as long as enough contrast remains for scanners.
How to Use
Follow these steps to create a QR code:
- Type or paste your content into the content field — a URL, plain text or any short string.
- Watch the preview update automatically as you type.
- Adjust the size slider for the pixel dimensions of the exported PNG.
- Set the margin if you want more quiet space around the code.
- Pick an error tolerance level: higher levels survive damage and logos, lower levels keep the code less dense.
- Optionally choose custom foreground and background colors.
- Download the code as PNG or SVG, or copy the image straight to your clipboard.
Before printing, always scan the code with a real phone camera to confirm it reads correctly with your chosen colors and size.
Features
- Generate QR codes from any text or link, live as you type.
- Adjustable output size from 128 to 1024 pixels.
- Adjustable quiet-zone margin.
- Four error-correction levels: L (7%), M (15%), Q (25%) and H (30%).
- Custom foreground and background colors.
- Download as PNG bitmap or scalable SVG vector.
- One-click copy of the QR image to the clipboard.
- Codes encode your content directly — no redirect service, no expiry, no tracking.
Frequently Asked Questions
Do these QR codes expire?
No. The code encodes your content directly, so it works as long as the content itself (for example, the linked page) exists. There is no account, server or subscription involved that could deactivate it.
PNG or SVG — which should I download?
For web use and messaging, PNG at 512 pixels or more is fine. For print — posters, packaging, business cards — choose SVG, because it scales to any physical size without going blurry.
Can I put a logo in the middle of the QR code?
Yes, indirectly: set the error tolerance to Q or H, download the code, then overlay your logo in an image editor. The extra redundancy lets scanners read the code even with part of the center covered. Always test-scan the final result.
Will custom colors still scan?
They will as long as the foreground is clearly darker than the background. Scanners rely on contrast, so avoid pale-on-pale combinations, and never invert to a light code on a dark background unless you test thoroughly — some scanners struggle with inverted codes.
Is there a length limit for the content?
QR codes hold up to a few thousand characters, but codes get denser as content grows, which makes them harder to scan at small sizes. For links, shorter is better — the preview updates live, so you can see the density before downloading.
Is my content uploaded anywhere?
No. Encoding happens entirely in your browser. Nothing you type is sent over the network, which makes the tool safe for private links, Wi-Fi passwords and internal URLs.
