File QR editor.

No. QRKong generates a QR code that encodes a URL you provide — you need to host the file yourself and paste in the direct link.

Common options: Google Drive, Dropbox, S3, or your own server. Make sure the link is publicly accessible before printing.

Any file that can be accessed via a public URL works — PDF, DOCX, XLSX, PNG, ZIP, and so on.

PDFs are the most reliable choice for print materials because every phone can open them without installing anything extra.

QRKong itself has no size limit — it just encodes a URL. The practical limit depends on your hosting provider and how quickly you want the file to load on a mobile connection.

For scanned materials, keep files under 10 MB when possible. Large files on slow connections frustrate users who just scanned your code.

The phone opens the URL in its default browser. Depending on the file type and the browser settings, it will either preview the file inline (common for PDFs) or prompt the user to download it.
