QR code generator

No. Encoding runs entirely in your browser with JavaScript. Your content is not uploaded, stored, or logged anywhere, and closing the page discards it completely.

Higher correction levels (Q or H) add redundancy so the code scans even when partially damaged or obscured. They make the matrix denser, so allow a slightly larger size for the same content to keep scanning reliable.

Yes, the code is a standard QR readable by any phone camera, Instagram, and dedicated scanner apps. Keep the white quiet zone clear and display it at the size that matches your export choice.

SVG is resolution-independent vector data, so it prints sharp at any size - essential for packaging, stickers, and large displays. PNG is a bitmap, better for previews, email, and social posts where the exact pixel dimensions are fixed.

Any text, including URLs, WiFi configs (as plain network strings), email addresses, phone numbers, or bulk text. For a rich QR that opens an app directly, use the URL of a deep link.

No. A QR code only needs strong contrast between modules and background. Dark on light reads most reliably, but colored QR codes work if the contrast stays high and the quiet zone is kept clear - the code generated here stays classic black-on-white for maximum scan reliability.

Yes, designers often overlay a small logo in the center of a QR, and higher error-correction levels (Q or H) tolerate that damage to the pattern. Keep the logo to about 15-20% of the code width and away from the three finder squares in the corners.

They work identically as long as the customization does not break the timing: keep high contrast, a clear quiet zone, and enough open space. This is why designers choose a stronger error-correction tier (Q or H) when they plan to add logos or colors.

Yes, QR codes are proportionally resizable. Scan reliability depends on printing resolution and distance: on a business card, print at minimum the size shown by the export size you choose, and for packaging or posters simply scale up - the same vector SVG stays crisp at any print size.

A customized QR carries your brand, looks intentional on packaging and marketing, and typically earns more scans because it signals a trusted brand rather than a plain square. The module pattern is the same; only the presentation changes.

A dynamic QR stores a short redirect link instead of your destination, so the code itself never changes while the target behind it can be edited later - and scanners are often tracked. This page creates static QR codes that embed the data directly and never expire.

A static QR encodes your destination directly, so it never changes and needs no network to scan. A dynamic QR encodes a redirect URL, letting you update the destination, fix typos, and track scans - at the cost of depending on a QR hosting service.

Yes - that is the main reason for using a dynamic QR. Because it only encodes a short redirect link, you can change where that link points after the code is already printed. A static QR, like the ones generated here, is permanent once created.

No. A dynamic QR must contact a redirect service when scanned, so it needs a network connection to work. A static QR stores its data directly in the pattern, so it scans and resolves entirely offline - which is why static codes are safer for permanent, physical print.

Use them where content changes or you want analytics: menus, brochures, event posters, and campaigns whose targets you may edit mid-flight. For links, WiFi passwords, or contact details printed permanently, a static code generated here works fully offline for life.

Dynamic codes are only valid while the hosting service keeps the redirect link alive and paid for. Static QR codes contain their data directly, so they never expire and need no service - the print is the data.

Dynamic codes are usually generated in batches through a hosting dashboard. Here, you can generate as many permanent static QR codes as you want, one after another with no limit, and download each as a PNG or SVG.
