Free Online HEIC to STL Converter

Welcome to our HEIC to STL image to 3D model file converter that will take your HEIC image file and convert it into a full 3D model that you can then download in the STL format using either a heightmap or extrusion process. Our tool supports up to 20, HEIC to STL conversions at one time, allowing you to batch convert your files quickly.

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

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

Our HEIC to STL converter offers several options when converting your HEIC image files; these options are accessed by clicking the button next to your file once selected. Some of the options available include the choice of mode, which can be either heightmap or extrude (with color as an additional option), the dimensions, smoothing options, and more.

File information for HEIC and STL

Full NameHigh Efficiency Image File Format
Mime Typeimage/heic

An HEIC file is a relatively new image format created to offer greater quality and compression ratios than older formats such as JPG. HEIC has found widespread adoption among image editing software thanks to the use of the format by Apple on their phones and tablets.

Apple's adoption of the format was critical. Photos taken on Apple devices, such as their smart phones, being saved to the HEIC format has created a lot of interest in the format and a desire from third parties to support it.


As HEIC was designed to be a direct replacement for the JPG format, it shares the same uses; for example, it is best used for storing photographic images rather than logos and other images that require a lossless compression format.

The STL file format is used for storing 3D models and is a common format for distributing 3D printable models. STL files emerged in the 1980s as a format for storing a 3D mesh as a simple list of triangles. Due to its age and simplistic format, it has gained widespread support within 3D modeling and CAD applications.

As a result of the simple file format and its widespread support amongst 3D editors, the STL format has found itself as the format of choice for the distribution of 3D printable objects. There are many websites that offer 3D printing downloads in the STL format.

Mesh Geometry

As mentioned, STL files make use of a simple structure for containing the 3D mesh data. The 3D model is stored as a continuous list of triangles, with each triangle containing three vertices specifying the location in 3D space of the triangle, which, along with a single vector normal, is all that is required to render the model contained within the STL file. There are two formats of STL files: plain text and binary. When used with large and complex 3D models, the text format leads to very large file sizes and should be avoided, with the binary format offering more efficient storage of the mesh data.

Frequently Asked Questions

How do I convert my HEIC to STL?

First, click the "Select File" button and choose your HEIC file. We will upload and convert your HEIC file. Once the conversion from HEIC to STL completes, use the provided link to download your STL file.

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

We aim to process all HEIC to STL file conversions as soon as possible; this should take around 5 seconds; however, this may be longer for larger files.

How is my HEIC image turned into a 3D model?

Our tool uses a heightmap process in which the STL model is created based on the color and brightness of the individual pixels in your HEIC image.

Is there a size limit for uploaded image files?

Yes, our conversion tool has a limit of 600x600 pixels for the HEIC image and will resize any file that is larger than this.
