Why can’t my laser software open WebP?

WebP is a web image format, and most CAD and laser software was built around DXF, SVG and older picture formats. Converting to DXF gives you outlines instead of a picture.

What happens to an animated WebP?

Only its first frame is traced. Save the frame you want as a still image if you need a different one.

Does a transparent WebP work?

Yes. Transparency is filled with white before tracing, so dark artwork on a transparent background is outlined and the background is ignored.

What size will the DXF be?

It has no units: one pixel is one unit, so a 600-pixel-wide WebP is 600 units wide (600 mm if your software assumes millimeters). Scale it after importing.

Why is the outline rough?

Small website pictures have few pixels and soft edges, and the tracer follows them. A larger version of the same picture gives smoother curves.

What happens to my files?

The WebP is uploaded over HTTPS, traced on our server and deleted automatically within 2 hours, along with the DXF.

How to Convert WebP to DXF

1
Upload the WebP
The .webp file your browser saved, up to 50 MB (up to 10 files at once).
2
Dark areas are outlined
The picture is flattened onto white and every area darker than mid-gray gets a closed outline.
3
Scale it in your software
Open the DXF in LightBurn, Fusion 360 or AutoCAD and set its real size.

Pictures saved from websites

Many websites serve pictures as WebP, so “Save image as” often gives you a .webp file instead of a JPG or PNG. Many CAD and laser programs cannot open WebP, and those that import pictures place them as an image, not as outlines to cut. This converter traces the picture into outlines your software can cut, engrave or edit.

What happens to a WebP before tracing

In the WebP	Before tracing
Transparent background	Filled with white, so only the artwork is outlined
Animation	Only the first frame is used
Colors	Turned to gray; anything darker than mid-gray is traced
Light parts (yellow, pale gray)	Treated as background and left out

Working with the DXF

Each dark area becomes a closed POLYLINE, with a separate outline for every hole. There is no fill, color or unit in the file: one pixel of the WebP is one drawing unit, so a picture 600 pixels wide arrives 600 units wide.

Measure one length you know after importing and scale the whole drawing to match.
Delete stray specks from the background before cutting.
In Fusion 360, closed outlines can be extruded into a part.

Choosing a good picture

Website pictures are often small, and small pictures trace roughly. Use the largest version you can find.
Logos, icons, silhouettes and line art trace cleanly; photos give blotchy outlines.
A white or light logo made for dark backgrounds comes out empty. Use the dark version.
