Tools that run in your browser

Every tool on this page works entirely on your own computer. There's no account, nothing is uploaded, and your label text and font files never leave the page. That matters when labels contain customer names or product details you'd rather not paste into a stranger's server.

Which one should I open?

If you know what size you want in millimetres and need the number of dots, use the size calculator. If you need a quick label and don't want to type ZPL by hand, the label generator writes it for you. If you've already got ZPL and want to see what it will look like, paste it into the live preview. If a font or script won't work on your printer, the text-to-graphic converter turns text into a picture the printer can always print. And the cheat sheet is for sticking beside the printer.

How they fit together

The tools are designed to hand work to each other. The generator and the converter can open their output in the preview with one click, and the calculator's numbers go straight into a label. A common flow is: work out sizes in the calculator, build a layout in the generator, refine it in the preview, then print a single test label. The article on testing ZPL labels without wasting media turns that into a routine.

What they can't do

They don't talk to your printer. You copy the ZPL and send it with your usual software, or save it as a file. They also approximate: the preview draws fonts with stand-ins, so it shows layout, not letter shapes, and no screen can show you how your media and heat settings will behave. Treat the tools as a way to get most of the way there quickly, and finish with a real test print.

Learn while you use them

If you'd like to understand what the tools are producing, the ^A command guide and the ten commands every developer should know explain the syntax. For graphics, read printing any font as a ^GF graphic. And if you've got an idea for a tool we haven't built, let us know.
