Files & datasheets

Upload files to qr3 and link them to a code — perfect for product datasheets, manuals or certificates.

Attach files to a code

1. Open the code’s detail page in the dashboard.
2. In the Files section, upload one or more files (PDF, images, …).
3. Choose the visibility when uploading:
   • Public (pre-selected in the dashboard) — served at a stable link and shown on the code’s landing page.
   • Private — uncheck Public to store the file without serving it publicly.

One code, several datasheets

A code can hold multiple files. To let a single scan reach all of them, enable landing page mode: the scan opens a qr3-hosted page listing every public file of that code.

Note

In the dashboard the Public option is pre-selected, so uploaded datasheets appear on the landing page right away — uncheck it for files that should stay private. Visibility is chosen at upload time.

Update a datasheet without reprinting

Use Replace on a file to swap its contents while keeping the same download address. The printed QR code keeps working: the link stays identical, only the file behind it changes. Upload the new version, and scans serve the updated datasheet.

Tip

Point your printed code at the landing page (not a single file’s direct link) when you expect frequent changes — the landing page always lists the current files. Note that a replaced public file may take up to a few minutes to propagate through caches before everyone sees the new version.
