How to Make a QR Code for a PDF

The brochure is a PDF on your laptop, and the code on the flyer has to open it on a stranger's phone. Between those two things, the file needs to live somewhere a phone can reach.

A QR code cannot hold a PDF. It holds a link, and the link opens the file. So the job is really two jobs: putting the PDF online, then making a code for where it lives.

Two ways to do it

• Upload it to a PDF QR code generator. One step. The file is stored for you, and the code opens a page with the document on it.
• Put it on Google Drive and make a code for the link. Free, and fine for a one-off. Set the file's sharing to “Anyone with the link”, copy the link, and turn that into a code with any generator.

The Drive route has one weakness worth knowing before you print. The code works only while that file stays shared, in that account. Moving it, tidying the folder or changing who can see it breaks every printed copy.

Canva and other design tools make codes from links too, so the PDF still has to live somewhere first. They are the right place to design the flyer, not to host the file.

What the reader sees

With our PDF QR code generator, the code opens a short page rather than dropping the reader straight into a file viewer.

• A title and a line of description, so the reader knows they have the right document.
• A preview of the first page, made from the file you upload.
• Two buttons: one to view or download the PDF, one to share it. You can rename both, so “Open the price list” is fine.

Files can be up to 20 MB. That limit is generous on purpose, because a scanned brochure is routinely over a few megabytes.

Swapping the PDF without reprinting

Prices change, a phone number moves, the spring brochure becomes the summer one. If the code points at a page you control, none of that needs new print.

With ours, you open the code, upload the new file and save. The printed code keeps working, it now opens the new document, and the old file is deleted when you save, so last season's prices do not linger.

On Drive, the equivalent is “Manage versions”, which replaces an uploaded file while keeping its link. Uploading a new file the ordinary way gives it a new link, and the printed code keeps opening the old one.

Keep it small enough for a phone

Twenty megabytes is the most you can upload, not a target. Someone scanning on a train is on mobile data, and a heavy file is a long wait for a page that may never finish loading.

A few megabytes is comfortable. Scanned pages are what make a PDF heavy, and the same fix that gets a file under an email limit works here.

The how, with the numbers we measured: shrinking a PDF that is too big to email.

A menu is a special case

Restaurant menus have their own problems: diners on a phone at a table, prices that change weekly, and a PDF that is often the wrong format entirely. They are covered in a restaurant menu QR code done properly.

Before you print

• Open it on mobile data. Office Wi-Fi hides a slow file.
• Read the first page on a phone. A landscape A3 poster saved as a PDF is unreadable at phone width. If that is your file, a one-page summary may serve the reader better.
• Say what the scan opens. “Scan for the price list” earns more scans than a bare code.
• Test the printed proof, not the screen. A code that scans from a monitor can still fail on glossy card in a dim room.

Put the file somewhere you control, keep it light, and test it on a phone on mobile data. The code is the easy part.
