Free Online HEIC to STL Converter

With our HEIC to STL converter, you can effortlessly convert your HEIC image file into a 3D heightmap model, which can then be loaded into your favorite 3D editing software. Our image to STL tool can batch convert up to 20 HEIC files at one time and quickly turn them into 3D models.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your HEIC file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted HEIC file before this time.

Our HEIC to STL image conversion tool comes with a set of options allowing you to fine-tune the details of how the 3D model is generated. Once you have selected a file, you will see a button, which you can click to reveal adjustable properties such as whether the tool should use a Heightmap or Extrude algorithm to create the 3D model. There are also properties to control the size and detail of the model.

Frequently Asked Questions

How can I convert my HEIC file to STL?

First, click the "Upload..." button and select your HEIC file to upload. Your HEIC file will be uploaded to our servers. When the HEIC to STL conversion has completed, you can download your STL file right away.

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

We aim to process all HEIC to STL conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the HEIC to STL conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How is the 3D model generated from my HEIC image?

Our tool uses a Heightmap process whereby the STL 3D model is created based on the luminosity of the individual pixels in your HEIC image.

Is there a limit to the size of my image?

Yes, to ensure our tool converts the HEIC image quickly and with a reasonable final file size, your tool will resize any image larger than 600x600 pixels.

File format information for HEIC and STL

Extension	HEIC
Full Name	High Efficiency Image File Format
Type	Image
Mime Type	image/heic
Format	Binary
Opens With	Paint.Net, Photoshop

HEIC files are a highly compressed bitmap image file format created specifically to offer greater compression ratios than other formats, such as JPEG, while maintaining image quality. The HEIC format is a standard format created by the MPEG group and has gained support from some major players in the industry, including Apple.

Within an HEIC file, the image data is compressed using advanced compression algorithms that try to maintain image quality while drastically reducing the amount of storage space required. Image data can be stored in either lossy or non-lossy formats, with the lossy format offering the best compression ratio.

With HEIC files being used by Apple in their range of smart phones and tablets, HEIC has become widely adopted and is supported by many image and photo editing software. For applications that do not support HEIC yet, we have an array of HEIC converters that can convert to and from many other image formats.

Extension	STL
Full Name	Standard Triangle Language
Type	3D Model
Mime Type	application/vnd.ms-pki.stl
Format	Text
Opens With	Blender, MeshLab, CAD Assistant, DAZ Studio

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

Information for converting from HEIC to STL

Our HEIC converter will convert your HEIC file to a 3D model using the Heightmap process, whereby 2D pixels, based on their luminosity, are converted into 3D space to create a full 3D STL model ready for download for further processing in your favorite 3D editing package or for printing on a 3D printer.
