PDF4me lets you add a barcode to a PDF right in your browser, whether you need a scannable QR code for a link or a Code 128 label for tracking. Upload your document, set what the code should contain, and place it exactly where you want on the page. There is no software to install and no account needed to get started.
Barcodes turn a plain PDF into something a scanner can read, which is perfect for invoices, shipping labels, tickets, and inventory sheets. Because everything runs online, you can add a barcode from a laptop, a tablet, or your phone without changing a thing.
One tool covers both worlds. Add a classic barcode when you need a machine readable label, or drop in a QR code when you want people to scan straight to a website, a contact, or plain text.
A QR code is a great way to connect a printed PDF to something online, so readers can open a link or a form with their phone camera. Your barcode sits on top of the existing page without disturbing the rest of your content.
Different jobs call for different codes. PDF4me supports common barcode types, including QR Code for links and 2D data and Code 128 for compact text and numbers, so you can match the format your scanner or workflow expects.
Whether you are labelling stock, numbering documents, or sharing a link, you can pick the type that fits and generate a clean, sharp code every time.
You stay in control of what each code says and where it goes. Type in a URL, a serial number, an order reference, or any short text, and PDF4me encodes it into the barcode or QR code for you.
Then position the code on the page so it sits neatly in a corner, along an edge, or next to a specific field, ready to print or scan.
Your documents stay your own. Files are uploaded over an encrypted HTTPS connection, processed on protected servers, and removed automatically once your barcode has been added.
We do not sell your data or share your files, so you can add codes to invoices, contracts, and shipping documents with confidence.
If you add barcodes to documents regularly, you can skip the manual steps. The PDF4me API and ready made connectors for Zapier, Power Automate, and Make let you generate and place barcodes automatically inside the workflows you already use.
It is a dependable way for teams and developers to stamp codes onto PDFs at scale, such as adding a unique barcode to every invoice or label. See the Pricing page for higher limits and faster processing.
Adding a barcode is only the start. With PDF4me you can also edit, merge, protect, and mark up your documents from the same place, so your whole PDF workflow lives in one tool.
