About this tool
Stamping a QR code onto a PDF turns a static document into something a phone camera can act on instantly — a link to an updated policy, a payment page, a feedback form, or a tracking URL, printed right on the page itself instead of buried at the bottom in tiny text. Type in the URL or text to encode, watch a live preview render as you type, then choose which corner of the page it should sit in, how big it should be, and how far from the edge — apply it to every page at once, or only the ones you pick.
The QR code is generated once and drawn onto each targeted page as an image, leaving all of the existing page content completely untouched underneath it — nothing is covered up or clipped unless you choose a size and margin combination too large for the page, in which case this tool tells you exactly which page is too tight instead of silently producing a broken file. Everything happens in your browser: the PDF and whatever you type into the QR field never leave your device.
Frequently asked questions
Will the QR code still work if I resize or print the PDF?
Yes — the QR code is embedded as a real vector-scaled image within the PDF, so it scales cleanly with the page and prints at full resolution just like any other image. Just make sure the printed size stays large enough (QR codes typically need to be at least ~2cm/0.75in per side to scan reliably from a normal reading distance).
Can I encode more than just a URL?
Yes — the text field accepts any plain text, not just URLs: a Wi-Fi network name, a short message, contact details, an event reference number, or anything else you want a scanner to read. A QR code is just an encoding for arbitrary text; the "opens a website" behavior only happens if the text you enter looks like a URL.
