How to convert ICO to DWG

Upload your ICO file

Drop your .ico on the converter, click to browse, or paste a screenshot with Ctrl+V.

We trace the lines

Every frame inside the .ico is decoded and the largest one is chosen automatically, because it carries the most detail for the tracer to work with.

Download a real DWG

You get a native 2018-format DWG with editable LWPOLYLINE geometry on its own A-SKETCH layer — editable geometry, ready to draft on, not a picture to trace again.

What you get: lines, not pictures

A floor plan with solid walls, furniture and text — and the CAD geometry this converter produces from it. Walls keep both faces, every thin line is a single editable polyline, and labels become real editable text.

Example ICO floor plan before conversion — Input: raster image (solid walls, thin furniture lines, text)

Editable DWG vector drawing produced by the converter — Output: editable DWG polylines (walls outlined, lines centerlined)

About ICO to DWG conversion

An .ico is not one image but a small archive of the same picture at several sizes — 16×16, 32×32, 48×48 and, on anything made this century, 256×256. It exists so Windows and browsers can pick the right size without scaling, and it occasionally becomes the last surviving copy of a company mark after a rebrand: the website is gone, the design files are gone, but the favicon is still sitting in a backup somewhere.

That recovery job is what this page is for. Every frame is decoded and the largest is selected automatically, since more pixels means more for the tracer to work with. Be realistic about the ceiling: a 256×256 icon holds enough shape to give a usable DWG outline you can clean up and build a proper drawing from, while a 16×16 one is thirty or forty meaningful pixels and will produce a blocky approximation at best. Icons are usually solid shapes rather than line art, so expect outlined regions — both edges of every form — rather than centerlines.

Frequently asked questions

Which size inside the .ico gets used?

The largest frame, chosen automatically by pixel count. A 256×256 entry converts surprisingly well; a 16×16 one carries too few pixels to give clean geometry, and no upscaling can invent the missing detail.

Why is my icon traced as outlines rather than lines?

Because icons are usually solid shapes, not strokes. The tracer classifies ink by thickness: thin marks become centerlines, but a filled glyph is traced along both of its real edges — which is what you want if you plan to cut or engrave the shape.

Are multi-resolution and PNG-compressed ICO files supported?

Both. Frames are stored either as raw bitmaps or as embedded PNGs depending on the tool that made the file, and both encodings are decoded here. Multi-size icons are the normal case, not an edge case.

Can I recover a logo from just a favicon?

Well enough to redraw from, not well enough to publish. A 256×256 trace gives you accurate proportions and shape boundaries to draft over in your CAD. Treat the result as a template, not as final artwork.

What about the .ico's transparency?

Transparent pixels are composited onto white before thresholding, so only the visible glyph is traced. An icon designed as a white shape on transparency will need inverting before upload, since white-on-white leaves nothing to find.
