How do I create a QR code for free?

Open ToolSuite QR Code Generator, select your content type (URL, WiFi, text, etc.), enter your data, customize colors and style if desired, then download as PNG, SVG, or PDF. No signup, no watermarks, no limits. The QR code is generated instantly in your browser.

How do I make a WiFi QR code?

Select 'WiFi' as the content type, enter your network name (SSID), password, and encryption type (WPA/WPA2/WPA3). The tool generates a QR code that, when scanned, automatically connects the device to your WiFi network. This is perfect for restaurants, offices, and guest networks.

Can I add my logo to a QR code?

Yes. Upload your logo image in the Logo section. Adjust the logo size and padding to fit within the QR code. The tool automatically increases error correction to H (30%) when a logo is present, which ensures the QR code remains scannable even with the logo covering part of it.

What is QR code error correction?

Error correction allows QR codes to be scanned even if part of the code is damaged or obscured. There are four levels: L (7% recovery), M (15%), Q (25%), and H (30%). Higher levels make QR codes more robust but increase their complexity. Use H when adding logos, and L or M for simple, unobstructed codes.

What size should my QR code be for printing?

For print, the minimum recommended size is 2x2cm (about 0.8x0.8 inches) for close-up scanning. For posters or signage, use at least 10x10cm. A general rule: the scanning distance should be about 10x the QR code size. Export as SVG or high-resolution PNG (2000px+) for print quality.

How do I create a vCard QR code for my business card?

Select 'vCard' as the content type and enter your contact details: name, phone, email, organization, title, and website. The generated QR code follows the vCard 3.0 standard. When someone scans it, their phone automatically offers to save your contact information.

Is it safe to generate QR codes with this tool?

Yes. ToolSuite generates QR codes entirely in your browser using the qr-code-styling library. Your data (WiFi passwords, contact details, URLs) is never sent to any server. The QR code image is created locally on your device. This is especially important for WiFi passwords and personal contact information.

What's the difference between PNG and SVG QR codes?

PNG is a raster (pixel-based) format — great for digital use but can pixelate when scaled up. SVG is a vector format that scales to any size without quality loss — ideal for print materials, banners, and large displays. Use PNG for web/digital, SVG for print. ToolSuite also offers PDF for print-ready output.

How many characters can a QR code store?

A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric digits at the lowest error correction level. However, more data means a more complex (denser) QR code that's harder to scan. For best results, keep content under 300 characters — use URL shorteners for long links.

Can I customize the colors and style of my QR code?

Yes. ToolSuite offers full customization: choose any foreground and background color, select from 4 dot styles (square, rounded, dots, classy), pick 2 corner styles (square, dot), and add your logo. Always ensure sufficient contrast between foreground and background for reliable scanning.

1. Introduction

ToolSuite ("we", "us", or "our") operates a suite of free online tools at toolsuite.app and its subdomains. This Privacy Policy explains what information we collect, how we use it, and your choices regarding that information. By using any ToolSuite product, you agree to the collection and use of information as described in this policy.

2. Information We Collect

We collect anonymous usage analytics to improve our tools. This includes: actions performed within the tool (such as button clicks, feature usage, and settings selections); file metadata such as file size, file type, and dimensions (we never access or store the contents of your files); randomly generated session identifiers; timestamps of interactions; browser type, version, and language; operating system and device category (desktop, tablet, or mobile); screen resolution; and referring URL. We do not collect names, email addresses, IP addresses in our analytics storage, or any other personally identifiable information.

3. How We Collect Information

Usage analytics are collected via HTTP POST requests sent from your browser to our API endpoints when you interact with a tool. Each interaction (such as compressing an image, formatting JSON, or generating a QR code) sends a small analytics payload containing only the anonymous data points listed above. File processing happens entirely in your browser. Your files are never uploaded to our servers for processing.

4. Why We Collect Information

We use anonymous usage data to: understand which features are most used so we can prioritize improvements; identify usability issues and bugs; guide product development and new feature planning; monitor tool performance and reliability; and analyze aggregate usage patterns across our suite of tools.

5. Cookies and Local Storage

ToolSuite uses minimal browser storage. We store a session identifier in sessionStorage that expires when you close your browser tab. Your dark mode preference is saved in localStorage under the key "toolsuite-dark-mode". A cookie consent acknowledgment flag is stored in localStorage under "ts_cookie_consent". We do not use tracking cookies. We do not use third-party advertising cookies. We do not use fingerprinting techniques.

6. Third-Party Services

ToolSuite does not currently use any third-party analytics services, advertising networks, or tracking pixels. All analytics are collected and processed by our own infrastructure. If this changes in the future, we will update this policy and notify users via the cookie consent banner.

7. Data Retention

Anonymous analytics data is retained indefinitely in aggregate form. Because the data contains no personally identifiable information, it cannot be linked back to any individual user. Session identifiers are randomly generated per browser session and are not associated with any user account or identity.

8. Your Rights

Because we do not collect personally identifiable information, traditional data subject rights under GDPR (such as access, rectification, or deletion requests) do not apply to our anonymous analytics data, as there is no personal data to access, correct, or delete. If you prefer not to send analytics data, you can use browser extensions that block outgoing requests to our analytics endpoints, or disable JavaScript (though this will prevent the tools from functioning). You may clear your localStorage and sessionStorage at any time through your browser settings to remove the session ID, dark mode preference, and cookie consent flag.

9. Children's Privacy

ToolSuite tools are general-purpose utilities not directed at children under 13. We do not knowingly collect any personal information from children. Since we collect no personal information from any user, there is no children's data at risk.

10. Data Security

All communication between your browser and our servers is encrypted using TLS (HTTPS). File processing occurs entirely client-side in your browser using JavaScript and WebAssembly, meaning your file contents never transit our network. Analytics payloads contain only the anonymous data points described above.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last Updated" date at the top of this page. Continued use of ToolSuite after any modifications constitutes acceptance of the revised policy. For significant changes, we will display a notice on our tools.
