Ballooning for CMM, CNC and inspection reporting

Drawing ballooning (also known as bubble drawings or ballooned prints) is the first step in most quality inspection workflows. Before you write a CMM program, complete a first article inspection (FAI / AS9102), or build a dimensional inspection report, every dimension on the drawing needs its own balloon number. This free tool lets you balloon a PDF or scanned drawing right in your browser and export a clean, numbered print to hand to inspectors, machinists, or your CMM operator.

Who uses this free ballooning tool

  • Quality engineers preparing first article (FAI), PPAP and dimensional inspection reports.
  • CMM programmers numbering features before writing a measurement program.
  • CNC machinists and inspectors checking machined parts against the drawing.
  • Manufacturing, aerospace and automotive teams that need fast, traceable drawing markup.

Why it is 100% free

No login, no email, no ads, and no watermark on your exported PDF. The entire tool runs in your browser, so there is nothing to install and nothing to pay for. When you are ready for full inspection reports with automated tolerance checks, dimension tables and CMM data import, QA-Report's CMM inspection software picks up where this free ballooning tool leaves off.

Frequently asked questions

What is drawing ballooning?

Ballooning means adding small numbered markers, called balloons, onto a drawing so every measurement has its own number. Inspection and quality teams use those numbers to check each dimension. This free tool lets you add balloons to a PDF or image and download the result.

Is this drawing ballooning tool free?

Yes. It is completely free and there is no signup. Open the page and start ballooning right away.

Can I balloon a multi-page PDF?

Yes. You can move between pages and add balloons on any of them. The numbers stay in order across the whole document, and the PDF you download includes the balloons on every page.

What file types can I upload?

PDF, PNG, and JPG. If you upload an image, you get back a one-page PDF with your balloons on it.

Is my drawing private? Do you keep a copy?

Yes, it is completely private, and no, we never keep a copy. The tool works right inside your web browser, like a calculator or a photo app on your own computer. Your drawing opens on your device, you add the balloons on your device, and the finished PDF is created on your device. We never receive your file and it is never sent anywhere.

How can I be sure my drawing is not sent anywhere?

Turn on airplane mode, or switch off your Wi-Fi, and then use the tool. It keeps working perfectly even with no internet at all. That is only possible because everything happens on your own device. If your drawing were being sent somewhere, the tool would stop working the moment you went offline.
