Generate a QR code for links, docs, menus, and flyers in seconds.
About the QR code generator
The QR code generator turns a link or block of text into a scannable QR code you can download as a PNG. Paste a web address, a note, or any string, set the image size, and press generate to get a code ready for a flyer, a menu, a business card, a slide, or a product label. People scan it with a phone camera and land on your link or read your text, no typing required.
You control the output size in pixels, so you can make a small code for a sticker or a large one for a poster. The image downloads straight to your device, and the text you enter is sent only to build the code image, not stored on this site.
How to use
- Type or paste your link or text into the URL or text box. A full web address starting with https works best for scanning.
- Set the QR size in pixels (from 160 up to 640) to match where the code will be printed or displayed.
- Press Generate QR code to render the code in the preview area below the inputs.
- Scan the preview with a phone camera to confirm it opens the right link or shows the right text.
- Select Download QR code to save it as a PNG image you can drop into your design.
Worked examples
https://stsapps.biz to QR code
Paste a homepage or landing page link to give print readers a one-scan path to the site.
Wi-Fi note or address text to QR code
Encode plain text such as a guest Wi-Fi note or a meeting room address so people can scan instead of copying it by hand.
Size 320 for a flyer, 600 for a poster
A smaller pixel size suits a handout, while a larger size keeps the code crisp when blown up on a wall poster.
Frequently asked questions
- What can I put inside a QR code here?
- Any link or plain text. A full URL is the most common use because scanning opens it directly, but short notes, an address, or any string of characters also work and will display as text when scanned.
- What size should I choose?
- Pick a size in pixels that fits where the code will appear. Around 160 to 320 pixels suits screens and small print like cards or stickers, while 480 to 640 keeps the code sharp on posters and large signs. You can regenerate at a different size anytime.
- How do I download the QR code?
- After you generate it, use the Download QR code link below the preview. It saves a PNG file named qr-code.png that you can place into a document, slide, or design file.
- How do people scan the code?
- Most modern phones scan QR codes with the built-in camera app. The person points the camera at the code, and a tap on the link that pops up opens it. No separate scanner app is usually needed.
- Will the code still work after I edit the text?
- Each code is tied to the exact text you generated it from. If you change the link or text, generate again so the new code matches. An old downloaded image keeps pointing at the original content.
- Does a printed QR code expire?
- The code itself does not expire; it always encodes the same link or text. What can break is the destination, so if the URL it points to is taken down or changed, the code will lead to a dead page even though the image is intact.
- Is the text I enter stored or shared?
- Your text is sent only to render the QR image and is not stored on stsapps.biz. Generation happens for that image request alone, and no account or sign-up is required.
