I made a free tool that merges a folder of certificate PDFs into one file so you can print them all in a single print job
If you've ever bulk-created certificates in Canva (or mail merge in Word), you know the annoying part isn't making them — it's printing them. You end up with 50 separate PDFs and have to open each one, hit print, repeat.
So I built a small free tool that fixes exactly that: drop in all your certificate PDFs, it merges them into one file, and you print once. That's it.
A few things I made sure of:
- Everything runs in your browser — nothing is uploaded anywhere. Certificates have people's names on them, so I didn't want files touching a server.
- No signup, no watermark, no file limits.
- Mixed page sizes/orientations are preserved as-is, so landscape and portrait certs print fine together.
- The single merged PDF is also handy if you're handing the batch to a print shop for cardstock or parchment.

Would love feedback — especially if there's an edge case in your certificate workflow this doesn't handle.
