PDF QR Code Best Practices
Follow these tips to maximize the performance of your pdf QR codes.
Optimize PDF for Mobile
Use large fonts (14pt minimum), high-contrast colors, and a portrait orientation for the best mobile reading experience.
Compress Before Uploading
Use tools like iLovePDF to reduce file size. Smaller PDFs load faster on mobile connections.
Add a Download Button
Ensure your PDF landing page has both a viewer and a download option for users who want offline access.
Version Control
Keep older PDF versions archived. When you swap a document, track the date of change for your own records.
Frequently Asked Questions
Common questions about pdf QR codes answered.
Can I encode a PDF directly into a QR code?
No. QR codes can only store text data (up to ~4KB). Qodex hosts your PDF and encodes a short URL that opens the document when scanned.
Is there a file size limit?
Qodex supports PDF uploads up to 20MB. For larger files, we recommend compressing the PDF or splitting it into multiple documents.
Do recipients need a PDF reader app?
No. Both iOS and Android open PDFs natively in the mobile web browser. No additional apps are required.
Can I replace the PDF without changing the QR code?
Yes. With a dynamic QR code, you can swap the hosted PDF file anytime in your Qodex dashboard. The printed code remains identical.
