Stamp QR Code on PDF (Free, Private, No Upload)
Adding QR codes to PDFs creates scannable links for quick access to websites, verification systems, or digital resources directly from printed or digital documents. Marketing teams adding campaign tracking codes, educators linking to online resources from printed handouts, event organizers embedding registration URLs, or businesses creating scannable product documentation all benefit from QR code stamping. This tool generates and embeds customizable QR codes directly into your PDFs within your browser, without uploading files to external services. Create codes linking to any URL, encode contact information, embed WiFi credentials, or generate verification codes for document authenticity. Position codes anywhere on the page—corners for subtle branding, headers for easy scanning, or prominently in the center for call-to-action purposes. Perfect for adding registration links to event flyers, embedding product manual URLs in warranty documents, creating contactless menu access in restaurant PDFs, or linking certificates to verification databases. The QR codes are embedded as high-quality vector graphics that remain scannable at any print size, and you can customize size, position, and which pages receive codes for professional integration with your document design.

FAQ
What can QR codes contain?
QR codes can encode URLs (links to websites), plain text, email addresses, phone numbers, WiFi credentials (SSID and password), or vCard contact information. Choose the encoding type based on what action you want when someone scans the code.
Can I customize QR code appearance?
Yes, adjust the size, position, and which pages receive the code. While the QR pattern itself must remain black and white for scannability, you can control placement and size to fit your document design and branding requirements.
Will codes work when printed?
Yes, QR codes are embedded as scalable vector graphics that maintain quality and scannability at any print size. Test scan before mass printing to ensure adequate size—generally, codes should be at least 1 inch square for reliable smartphone scanning.
Can I add different codes to different pages?
Currently, this tool applies the same QR code across selected pages. For different codes per page (like unique tracking URLs), you'll need to process the PDF multiple times or use advanced PDF editing software.
Are files uploaded?
No, QR code generation and embedding happen entirely in your browser using JavaScript. Your documents remain on your device, ensuring privacy for internal business documents, confidential reports, or any sensitive materials.
