Place GD&T callouts on PDF and image drawings straight in the browser — auto-numbered, drag-to-adjust leader lines, and vector export ready for inspection. No install. No upload to a server.
Quality engineers still balloon drawings by hand in generic markup tools built for contracts, not tolerances. BallooningIQ is built for the callout — auto-numbered, GD&T-aware, and gone the moment you close the tab.
Five balloon shapes, a full GD&T symbol set, and leader lines that actually behave.
Circle, oval, square, hexagon, and flag — pick what matches your drawing standard.
Flatness, position, runout, diameter, and more — drawn to spec, not typed as text.
Four numbering formats. Renumber a whole sheet top-to-bottom in one click.
They stop at the balloon's border, not its center — and you can drag the arrow tip by hand.
Merge PDFs and images, reorder or rotate sheets, balloon each page independently.
No account, no upload. Your drawing is processed entirely on your own machine.
No account to create before you can see it work.
Drag in a PDF, PNG, or JPG. Multiple files merge into one working set automatically.
Click to place, drag to adjust position and leader length, numbers increment on their own.
Vector PDF, print-ready, balloons burned in — hand it straight to inspection.
Start free. Move to Pro when a sheet outgrows it.
No signup. No install. Just open a PDF and start clicking.
