Generator kode QR
A QR code is a fast way to share a link, text, or contact from a flyer, business card, or menu. Paste the content, generate the image, and download PNG. The code is built in your browser — we do not create a tracking account for scans.

How to create a QR code
1. Enter text or a URL.
2. Click “Generate QR code”.
3. Check the preview.
4. Download PNG and use it in print or online.
Use cases
Link to a site or menu
Paste https://… on a menu card, event poster, or email footer. A guest scans and opens the page immediately.
Business card
Encode mailto:jane@company.com or a LinkedIn link. On paper it takes very little space.
Wi‑Fi or short instructions
You can encode a short text with a password or instructions. Remember that anyone with a scanner can read it — do not put secrets on public materials.
When to use it
• When you want to move a link from paper to a phone.
• When you prepare printed materials (flyers, posters, packaging).
• When you need a simple PNG without a third-party account.
When to be careful
• Do not encode confidential passwords on public posters.
• Very long text makes a dense code that is harder to scan from a distance.
• If you need scan analytics, this generator does not collect them (good for privacy, not for campaign stats).
How QR codes work
A QR code stores text in a grid of black-and-white modules with error correction. Longer content means more modules and a harder scan from far away or from a low-quality print. For posters, encode a short link (you can use your own short domain).
Print and contrast
A good code has high contrast, a quiet margin around it, and enough size. Avoid placing it on a busy patterned background. The PNG from this generator is black and white on purpose to maximize readability in home and professional printing.
Privacy vs. scan analytics
Some commercial generators offer scan stats because they redirect through their server. Here you create a static image with no tracking. If you need campaign analytics, use a separate link shortener; if you care about recipient privacy, a static QR is better.
Test before a big print run
Always scan the code with a phone before sending a design to print. Try a few angles and distances. If the code leads to a mobile page, make sure the site works on a small screen and does not need Flash or unusual plugins.
Pertanyaan yang sering diajukan
What can I encode?
Links, plain text, mailto:, tel:, and other short content. The longer the text, the denser the code.
Does a QR code expire?
The image does not expire. If it points to a link, validity depends on whether the destination still works.
What file format do I download?
PNG — universal for print and the web.
Can I use the code commercially?
Yes. You may use the generated image in your own materials.
Do you track scans?
No. This is a static image with no redirect server in the middle.
Why will a scanner not read my code?
Check contrast, print size, and whether the content is too long. Print a larger code.
Does it work offline after loading?
Generation is local; the first page load still needs the network.
Can I change the code colors?
The current version generates a classic black-and-white code for best readability.
