Can adding a logo make a QR code unscannable?
Not if done correctly. QR codes use error correction, which means they can still be decoded even with a portion of the pattern obscured. When you upload a logo, this tool automatically switches to High error correction (H), which recovers up to 30% of data loss. Keep your logo within 25–30% of the QR area for reliable scanning.
What logo format should I use?
PNG with a transparent background gives the cleanest result — the background of your QR shows through the transparent areas of the logo. SVG logos work best if your QR background is a solid color. Avoid JPG logos as JPEG compression creates jagged edges around the logo.
What should the ideal logo size be inside the QR?
Keep your logo within 25–30% of the total QR area. For a 300×300px QR, your logo should be no more than 75–90px wide. Larger logos may cause scanning failures even at High error correction. The tool enforces a safe margin automatically.
Does a white background on my logo matter?
If your logo has a white background on a white QR background, it blends in cleanly. If your QR background is a different color and your logo has a white background, you will see a white square behind the logo. Use a PNG with a transparent background to avoid this.
What colors work best for a branded QR code?
Use your brand's primary color for the QR dots (foreground) and a light variant or white for the background. Ensure strong contrast — light background and dark foreground is the golden rule. QR codes with very low contrast (e.g. light grey on white) may fail to scan reliably.
Can I use a circular logo in the QR code?
Yes, circular logos work beautifully. Most QR scanning apps render the logo within the bounds of the QR image. Since modern QR code styling supports rounded dot styles too, a circular logo with rounded dots creates a premium, modern look.
Which dot style looks best with a logo?
For a professional, modern look, try "Smooth" (extra-rounded) dots with an "extra-rounded" corner style. This pairing with a centered logo is the most popular choice for branded QR codes in print materials. Classic Square dots work well for high-density data.
Should I use PNG or SVG for printing a QR code with logo?
SVG for all professional printing. SVG is a vector format — infinitely scalable without pixelation. Use it for business cards, menus, packaging, and posters. PNG is fine for digital use at its native resolution (set the QR size to 400px+ for high-quality PNG exports).
Can I add a frame and text below the QR?
Yes. Open the Customization section, enable Frame & Label, and type your desired text — "Scan Me", "Visit Website", your brand name, or a call-to-action. The frame and label are composited when you download PNG. The frame uses your selected QR colors.
How do I make sure my QR code scans reliably after adding a logo?
Follow these rules: keep the logo under 30% of the QR area, use a PNG with transparent background, ensure sufficient contrast between QR dots and background, test by scanning the downloaded image before printing large batches. Use the High error correction level (automatically set when a logo is uploaded).
Can I add my logo to a WiFi, UPI, or vCard QR code?
Yes. The QR Code Generator supports logo upload for any QR type — URL, WiFi, vCard, WhatsApp, UPI, location, email, phone, and text. Select the QR type, fill in the details, then open Customization to add your logo.
