Yes! QRcode 88 offers a completely free tier that includes unlimited QR code generation, basic customization options, and standard download formats. We also offer premium features for users who need advanced functionality like analytics, custom domains, and bulk processing.

You can download QR codes in multiple formats including PNG (for digital use), SVG (for vector graphics and scaling), and PDF (for professional printing). Each format is optimized for different use cases to ensure the best quality.

No account is required for basic QR code generation. You can create, customize, and download QR codes immediately. However, creating an account allows you to save your QR codes, access advanced features, and manage your creations more efficiently.

Common scanning issues include: insufficient contrast between foreground and background colors, QR code is too small, poor lighting conditions, camera lens is dirty, or the QR code is damaged or distorted. Ensure your QR code has high contrast and is at least 2x2 cm for reliable scanning.

Yes! You can add your company logo to QR codes using our logo integration feature. Keep logos under 20% of the total QR code area and ensure high contrast for optimal scanning. We recommend using PNG format with transparent backgrounds for best results.

Our bulk generator supports generating hundreds or even thousands of QR codes at once. You can upload CSV files or use our URL pattern generator. For optimal performance, we recommend batches of 1000 or fewer QR codes at a time.

Static QR codes (containing direct information like text, URLs, contact info) are permanent and will work forever as long as the content remains accessible. The QR codes themselves don't expire, but if they link to websites or services that go offline, they may appear broken.

Free features include unlimited basic QR code generation, standard customization, and basic download formats. Premium features include advanced analytics, custom domains, white-label solutions, priority support, API access, and enhanced bulk processing capabilities.

We take privacy seriously. QR code generation happens in your browser when possible, meaning your data isn't sent to our servers. We don't store personal information unnecessarily, use industry-standard encryption, and comply with GDPR and other privacy regulations.

QR codes themselves cannot contain malware or viruses - they're just data containers. However, they can link to malicious websites. Always be cautious when scanning unknown QR codes and verify the URL before visiting any website. Our platform only generates legitimate QR codes based on your input.

Yes! We offer a comprehensive REST API that allows developers to integrate QR code generation into their applications. The API supports all our features including bulk generation, customization, and various output formats. Check our developer documentation for details.

Absolutely! You can cancel your subscription at any time from your account settings. Your premium features will remain active until the end of your current billing period, after which your account will revert to the free tier with no loss of previously generated QR codes.
