A QR code is a picture that can hold a short piece of text, such as a web address. Someone points a phone camera at the picture to read that text. QR Code Generator makes the picture in your browser.
Make one you can test
- Open the tool. In Text or URL, replace the example with
https://example.com. - Look at Preview. The square code should change as you type. There is no Generate button.
- Point a phone camera at the preview. Check that it offers
https://example.combefore you share the code. Scanning reads the address; opening it is a separate choice. - Choose Download PNG for an image file, or Download SVG for a file that can be scaled for print. Open the downloaded file and scan that too: it is the file people will actually use.
Change one setting at a time
Size changes the image size; it does not change the text inside. Margin adds empty space around the code. Keep some space so a camera can see where the code starts and ends. Error correction adds extra information that can help a damaged code still scan, but a higher level can make the pattern denser. Leave it at M for your first test.
You can add a logo in the middle, but it covers part of the pattern. Start without one. If you add one later, scan the downloaded result on more than one phone. The tool’s size hint is based on tests; it is not a promise that every camera and print surface will work.
If no code appears
Check that Text or URL is not empty. If the tool says it could not build the code, try shorter text. If a code appears but will not scan, try more margin, stronger contrast between Foreground and Background, or a smaller logo.
Where your input goes
Processing runs in your browser. The tool does not upload your input to ilham.dev.

Questions you might have
- Do I need an account, or is there a limit?
- No account, no API key and no quota. The generator runs entirely in the page.
- Which error-correction level should I choose?
- Start with M. If the code may be scratched or partly covered, try H. H adds more recovery information but makes the pattern busier. Download and scan the final image; the setting alone cannot guarantee that a phone will read it.
- Why did the PNG download fail?
- PNG download needs the browser to draw the image first. If that step fails, try Download SVG instead. SVG stays sharp when you make it bigger for print. Open and scan the downloaded file before sharing it.
- How large can a logo be before the code stops scanning?
- A logo hides squares that a phone needs to read. Make the logo small. The tool shows a warning when its size is beyond what scanned in testing, but that limit is not a guarantee for your image. Scan the downloaded file on a few phones, especially before printing many copies.
