QR Code Generator
Type or paste any link or text and watch the QR code appear as you type. It is generated entirely on your own device — nothing is sent anywhere.
- No uploads
- Runs locally
- No sign-up
Your text never leaves your browser — the code is generated locally.
Your QR code will appear here as soon as you start typing.
How to create a QR code
- Type or paste a link, some text, Wi-Fi credentials or anything else into the content box.
- The QR code appears instantly as you type — pick a size and an error correction level if you need to.
- Higher error correction keeps the code readable when printed small or slightly damaged; lower correction fits more data.
- Download the code as a crisp PNG image, or as an SVG that scales to any print size.
A QR generator that cannot see what you encode
Most QR generators send your text to a server and hand back an image — which means the server sees every Wi-Fi password, private link and phone number people encode. CoolPDF works the other way around: the generator code comes to your browser, and your text never leaves the tab. You can open the network panel while you type and watch — nothing is sent. That makes it safe for credentials, internal URLs and anything else you would rather keep to yourself.
Frequently asked questions
Do the QR codes expire?
Never. The code is a plain image of your content — there is no account, no redirect service and no expiry date. Once downloaded, it keeps working forever.
Can I use the codes commercially?
Yes. Everything you generate is yours — use it on packaging, posters, business cards or client work, free of charge and with no attribution required.
Which error correction level should I pick?
Medium (the default) suits most uses. Pick High when printing small or expecting wear — the code survives up to 30% damage. Pick Low to fit more data into one code.
Is my text uploaded anywhere?
No. The QR code is generated entirely in your browser with JavaScript. You can disconnect from the internet after the page loads — it keeps working.
Are there any usage limits?
No. Every tool is free with unlimited use — no daily caps, no quotas, and no sign-up. Your own device does the work, so there is no server cost to pass on. To keep your browser stable, each tool has a generous per-file size limit (50–150 MB depending on the tool), far more than everyday documents need.
CoolPDF is a free, browser-based PDF toolkit. Unlike traditional online PDF tools, CoolPDF processes all files locally on the user’s device using WebAssembly — files are never uploaded to any server. The tools require no account, no email, and no sign-up, and are completely free with no usage limits. This makes CoolPDF suitable for confidential documents such as contracts, medical records, and financial statements.
