Create QR codes from text or URLs
The MailDrop QR code generator turns any text or URL into a scannable QR code right in your browser. Type a web address, a piece of text, a Wi-Fi note, or contact details, choose a size, and the code is rendered instantly on the page. When it looks right, download it as a PNG image ready to drop into a document, a slide deck, a flyer, or a product label.
QR codes bridge the gap between screens, paper, and phones. They let people reach a URL without typing it, which is why they appear on menus, posters, business cards, event tickets, packaging, and conference slides. Generating your own code takes seconds here, and the size options let you produce anything from a small icon for a web page to a large, high-resolution image that stays sharp when printed.
The code is generated client-side by JavaScript, so the text or link you encode is never uploaded to any server, an important point when the content is a private URL or personal note. The tool is free with no registration, part of the same toolkit as MailDrop temporary email.
Type or paste the content you want to encode. A full web address with https is the most common choice, but any text works, including phone numbers, short messages, and identifiers.
Choose from the available size options depending on where the code will live. Larger sizes hold up better in print and scan reliably from farther away, while smaller sizes suit screens and tight layouts.
The code appears on the page as soon as it is generated. Point a phone camera at your screen to test that it scans and opens exactly the content you intended before you distribute it anywhere.
Click the download button to save the QR code as a PNG image. The file is created in your browser and saved directly to your device, ready for documents, print materials, or websites.
No. The QR code is drawn entirely by JavaScript running in your browser, and the PNG download is produced locally as well. Nothing you type is transmitted, stored, or logged, so you can safely encode private links, internal URLs, or personal notes without them leaving your device.
No. The code you download is a static image that permanently encodes exactly the text you entered, with no redirect service in between. It will scan forever. The only thing that can break is the destination itself, for example if the URL you encoded is later taken offline or changed.
A QR code can store up to a few thousand characters, but practical capacity is lower because denser codes are harder to scan, especially when printed small. Short URLs scan fastest and most reliably. If your link is very long, consider encoding a shorter address that leads to the same place.
Pick the largest size available when the code is headed for print, since a PNG scaled up beyond its pixel dimensions turns blurry and may fail to scan. As a rule of thumb, the printed code should be at least two centimeters across for close-range scanning, and larger for posters viewed at a distance.
QR codes on posters and packaging often lead to signup pages that demand an email address before showing anything useful. Scanning with a MailDrop disposable email inbox at the ready lets you register, grab the content, and walk away without handing over your real address, and you can generate codes for your own campaigns here just as privately.
