Free Laser Cutting & Engraving Tools

Free browser tools for laser cutting and engraving: box and living hinge generators, kerf and material test patterns, cut and engraving time estimators, power and speed starting points, DXF viewer and converter, nesting and cost calculators. No signup.

• DXF viewer

  Drag, drop and preview AutoCAD DXF files in your browser. Fully private.

• SVG ⇄ DXF converter

  Convert SVG to DXF and back, in your browser, ready for laser or CNC.

• Cut time estimator

  Drop a DXF or SVG: cut length, pierces and the time it will take at your speeds.

• Cut list optimiser

  Lowest-waste cutting plan for panels and linear stock, blade kerf included.

• Box generator

  Closed box, open tray, lift-off lid or divided tray with finger joints, as one SVG.

• Living hinge generator

  Six slit patterns, straight to honeycomb, that let a flat sheet bend, sized to your panel.

• Kerf test gauge

  Slot gauge and reference square to measure the kerf of your laser on any material.

• Material test grid

  Power × speed squares, one layer each, to dial in a new material in one burn.

• Spur gear generator

  True involute gears from module and tooth count, a meshing pair with its centre distance.

• Power & speed starting points

  Cutting speed, passes and engraving settings per material, scaled to your laser.

• Engraving time calculator

  Raster engraving time from size, line interval, speed and overscan.

• DPI ⇄ line interval

  DPI, LPI and mm interval, and the interval that matches your spot size.

• Spot size & depth of focus

  How small your lens focuses and how much height you have, from wavelength and focal length.

• Rotary attachment calculator

  Steps and mm per rotation for roller and chuck rotaries, and the wrap-around width.

• Inlay kerf offset

  How far to grow the insert and shrink the pocket so an inlay fits without a gap.

• Sheet gauge ⇄ mm

  Gauge to millimetres and back for steel, stainless, aluminum and SWG, with the tables.

• Nesting efficiency calculator

  Compute utilisation, waste and material cost from total part vs sheet area.

• Sheet utilization calculator

  Quick grid estimate of how many rectangular parts fit on a stock sheet.

• Kerf compensation calculator

  Toolpath offset so finished parts hit dimension after the kerf is removed.

• Laser cost per part calculator

  True landed cost of a laser-cut part: material, machine, labour and margin.

• Sheet metal weight calculator

  Weight of steel, aluminum, stainless and more from sheet size and thickness.

• Sheet metal price estimator

  Price per kg into price per sheet, per m² and per part, in EUR with VAT.

• Offcut and scrap value calculator

  What a remnant saves as reusable stock versus what it fetches as scrap.

• Material cost estimator

  Per-part material cost from sheet price, utilisation and scrap recovery.
