Laser tools that run on your device

Measure first.
Cut with intent.

Check your artwork, confirm its real size, measure kerf, prepare the job, and move to the offline Desktop app when it is time to work with a machine.

A clear path from file to finished plan

Know what you are cutting before you start

KerfCanvas keeps size, cut and engrave choices, measured settings, warnings, and saved steps together so you can see what changed.

01 / INSPECT

Know the file

Resolve units, dimensions, layers, open paths, duplicate cuts, fonts, and unsupported features.

02 / CALIBRATE

Know the material

Measure kerf, focus, interval, and fit for this machine, lens, material, and batch.

03 / PREPARE

Build the job

Create patterns, prepare engraving, arrange parts, choose cut order, and save your settings.

04 / MOVE TO DESKTOP

Review before cutting

Download the project and open it in Desktop before any machine action.

A clear safety boundary

The website prepares. Desktop connects.

The website never connects to, moves, starts, pauses, or resets a laser. Desktop checks your selected machine and setup again before supervised output.
