About the Barcode to PDF Engine
Retail, logistics, and inventory workflows rely on barcode formats that a plain QR generator can't produce — Code 128 shipping labels, EAN-13 and UPC-A retail codes, Code 39 asset tags, and 2D formats like Data Matrix and PDF417. iCreatePDF renders any of these symbologies and compiles them into a clean, print-ready A4 PDF entirely in your browser.
Zero-Server Privacy Architecture
Unlike conventional web utilities that transmit your files to cloud processing clusters, iCreatePDF executes barcode to pdf completely client-side. WebAssembly modules and local JavaScript engines handle all parsing, layout calculation, rendering, and file encoding inside your browser sandboxed memory buffer. Your files never cross network boundaries.

Frequently Asked Questions
Q: Which barcode format should I use?
Use EAN-13 or UPC-A for retail products, Code 128 or Code 39 for shipping and inventory labels, and Data Matrix or PDF417 when you need to encode more data in a compact 2D code.
Q: Why does EAN-13 or UPC-A reject my input?
These formats require a specific digit count (12–13 digits for EAN-13, 11–12 for UPC-A) including a valid check digit. Double check the code matches the official format.
Q: Is the barcode generated locally?
Yes, the barcode image and PDF are both generated entirely in your browser — nothing is uploaded to a server.
Q: What page size is the output PDF?
The barcode is compiled onto a clean A4 page, ready for printing onto labels or documents.
