High resolution QR code generator
Download a high resolution QR code for print: a 4096 px PNG by default, or SVG and PDF that have no pixel limit at all. The code is static, so it never expires and nothing routes through a server. It is free with no sign-up, made entirely in your browser, and verified by a real scanner before you download it.

Off by default. When on, each downloaded code (type, content, style) is saved in this browser only, never uploaded. You can delete them at any time.
How to make a high resolution QR code
- Paste the link into Website address.
- Size is already set to 4096 px on this page; 2048 px is enough for most office printing.
- Style it if you want with Style preset, Foreground colour or Upload logo, and keep the Quiet zone at 4 modules.
- Wait for Verified: scans as URL. Then Download PNG for a pixel file, Download SVG for a designer, or Download PDF for a fixed print size.
High resolution QR code details
Resolution matters only because a code has to be printed at some physical size and scanned from some distance. The generator renders the PNG at whatever Size you choose, and this page starts at the largest preset, 4096 px, so the file survives any office printer and most posters. A 29 × 29 code plus its quiet zone at 4096 px gives each module about 110 px, far more than any printer can resolve, so the pixels are never the weak link.
The print maths
Pixels divided by the printer’s dots per inch equals inches. 4096 ÷ 300 = 13.65 in, or 34.7 cm, on a typical 300 dpi press; at 600 dpi the same file is 17.3 cm. Down the range, 2048 px is 17.3 cm at 300 dpi and 1024 px is 8.7 cm. Larger than that and the printer has to upscale, softening the edges; the fix is a vector file, not more pixels.
When SVG or PDF beat any pixel size
Download SVG and Download PDF contain shapes rather than pixels, so a shop-front decal or a trade-show wall prints as crisply as a business card from the same file. SVG goes to a designer placing the code in artwork, PDF when the code must appear at an exact width on its own page, and PNG to screens, documents and tools that reject vector formats.
Module size and distance
What decides whether a code scans is the size of each module at the scanning distance, not the pixel count. The rule of thumb is width equals distance divided by ten: 5 cm for half a metre, 10 cm for a metre, 50 cm for five metres. Denser codes, meaning long addresses, level H or a logo, need more. The size guide turns that into a calculator; only a print test confirms the size.
This code never expires
Resolution changes how many pixels describe the pattern, never what the pattern says, so a large print of a static code works for as long as the address does. This is a static QR code: the data is written into the pattern, so scanning it needs no server, no account and no subscription. There is nothing to renew and no redirect that can be switched off, which is why a code made here keeps working for as long as the printed copy exists. The trade-off is honest: a static code cannot be edited after printing and does not count scans. If you need either, encode a link to a page you control. Read how static and dynamic codes differ, and if a code you already have has stopped working, see why QR codes expire.
Styling, formats and print size
Every code can be styled in the Style panel: six dot shapes, corner shapes, solid or gradient colours, a transparent background, a quiet zone of 0–8 modules, and your own logo up to 30 percent of the width. A contrast checker warns below 3:1 and blocks downloads below 1.5:1, and after each change the preview is decoded again so the badge tells you whether the styled code still scans.
| Output | Best for | Notes |
|---|---|---|
| PNG | Web, documents, quick prints | 256 to 4096 px; transparent background supported |
| SVG | Designers and print shops | Vector, scales without limit; logo embedded |
| Printing at an exact size | Vector modules at a chosen width in mm or inches, optional caption | |
| JPG | Platforms that reject PNG | White background; no transparency |
| EPS | Legacy print workflows | Vector from the module matrix, no logo |
| Copy / Print | Pasting into a document; a quick paper test | PNG to the clipboard; print view with caption |
Print size: as a rule of thumb the code should be at least one tenth of the scanning distance wide, with the quiet zone included.
| Scan distance | Minimum width |
|---|---|
| 0.5 m (arm's length) | 5 cm |
| 1 m | 10 cm |
| 2 m | 20 cm |
| 5 m | 50 cm |
4096 px prints at 34.7 cm on a 300 dpi press and 17.3 cm at 600 dpi; for anything wider, or when the shop asks for vector, send the SVG or PDF. Scan distance divided by ten gives the minimum width.
The QR code size guide has a calculator for module size, DPI and distance.
Frequently asked questions
How large can a high resolution QR code be printed?
The 4096 px PNG covers 34.7 cm at 300 dpi, which is most posters and window signs. Beyond that, the SVG and PDF downloads are vector and have no upper limit: a banner or a wall graphic prints from the same file with perfectly sharp edges.
Is an HD QR code the same as a high resolution one?
People use HD QR code to mean a crisp, large file, and that is what the 2048 and 4096 px sizes give you. Resolution above the printer's own dpi adds nothing, so the real goal is enough pixels per module for the print size, plus a vector file when the size is unknown.
Which format is best for a QR code for print?
For a print shop, PDF at the exact width or SVG for a designer to place. For an office printer, a 2048 or 4096 px PNG in your document at actual size. For a label printer, PNG at the label's native resolution. All three come from the same verified design.
Does a bigger file scan better?
Not beyond a point. Scanning depends on the size of each module at the scanning distance and on contrast, quiet zone and print quality. Extra pixels only stop the printer from softening the edges. A 4096 px file printed at 2 cm scans no better than a 512 px one.
How do pixels relate to centimetres?
Divide pixels by the printer's dots per inch to get inches, then multiply by 2.54. At 300 dpi, 1024 px is 8.7 cm, 2048 px is 17.3 cm and 4096 px is 34.7 cm. Layout programs let you set the width directly; keep the result at or above 300 dpi.
Can I go above 4096 px?
There is no larger PNG preset because vector is the better answer at that scale. **Download SVG** or **Download PDF** gives a file with no pixels at all, which any print shop can output at any width. If a tool insists on a raster image, export one from the SVG.
