Convert your ICO file to STL

to

Use our free and fast online tool to convert your ICO (Icon) image or logo into 3D STL (Standard Triangle Language) mesh/model files suitable for printing with a 3D printer or for loading into your favorite 3D editing package.

How to Convert your ICO to STL Online?

Here are three simple steps to create an STL file from a ICO file.

Upload a ICO

Click the "Upload a File" button and select ICO to upload. The maximum file size is 100MB.

Select your Options

Set the dimensions and other options, and click the "Convert to STL" button to convert your ICO to STL.

Download your STL

Click the download link once completed to receive your STL file.

Frequently Asked Questions

How can I convert my ICO file to STL?

First click the "Upload..." button, select your ICO file to upload. Select any configuration options. When the ICO to STL conversion has completed, you can download your STL file straight away.

How long does it take to convert my ICO to STL?

We aim to process all ICO to STL conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the ICO to STL conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my ICO to STL on ImageToStl.com?

Yes, of course! We do not store the ICO file you submit to us. The resulting STL file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert ICO to STL on Windows, Linux, Android, iOS or Mac OS?

Yes! Our ICO to STL tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our ICO conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

What is the maximum ICO image resolution I can upload?

The ICO image you upload can be any size, however our tool will resize it to a maximum of 800x800 pixels for normal users and for premium subscription holders this is increased to a maximum of 1200x1200 pixels.

What STL formats can I convert to?

Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.

Description

The ICO file is an image format that started life on Microsoft Windows 1.0 and was used exclusively for storing image icons used by the operating system. Back then, ICO files were limited in size to 32x32 pixels with only two colors. With subsequent versions of Windows, the format has been amended and upgraded to support larger images with more colors.

Although the initial ICO format was not compressed due to their already small sizes (and limited computing power to decompress them in real-time), as the size of image icons has increased over the years, Microsoft recommends that for larger icon files, PNG compression be used for storing the raster data.

Description

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format, namely SolidView and VisCAM, whose formats included limited 15-bit color information for each mesh face, which is often ignored by most modern 3D software. The STL format can be either text or binary; our tools will support both formats.

STL Notes

The standard STL file format does not support colored faces, vertices, or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default, which is perfect for 3D printing.

The tool also has the option to save the file to one of the non-standard formats that support colored faces, such as VisCAM and SolidView which is perfect if you want to further process the STL in software that supports these formats.

Supported Features

  • Mesh geometry
  • Face colors via the VisCAM and SolidView formats
  • Binary and text versions are supported

Converting Your ICO File for 3D Printing

Software used to prepare a 3D model file for printing, which is also known as 3D slicer software, cannot directly 3D print image files such as ICO. This is due to the fact that slicing software is designed for use with 3D models rather than flat 2D images.

Slicer software can, however, handle files formatted to the STL standard. This is because the STL format was specifically designed as a medium of storage and exchange for 3D printable models. Our ICO to STL conversion tool will first create either a heightmap or an extruded 3D model from your ICO image file. This 3D model can then be loaded into your slicer software and sent to your 3D printer for printing.
