3D stereogram generator

Create images with hidden 3D shapes from text, logos, silhouettes, or depth maps.

Depth map

3D stereogram

Look through the image

1:1 view. The image is not scaled down because changing the horizontal scale can affect the perceived 3D effect.

How to view the 3D figure

Look as though you are focusing on a point behind the screen. If you use the two guide dots, relax your eyes until a third dot seems to appear between them. Hold that focus and lower your gaze to the pattern to see the hidden shape.

Privacy:the depth map and stereogram are generated entirely in your browser. The images you select are not sent to UtiliTools Pro.

Create your own hidden 3D image

A stereogram, also known as an autostereogram, uses small horizontal variations in a repeating pattern to encode depth. UtiliTools Pro creates this pattern directly from a depth map generated from text or an uploaded image.

Hidden text

Convert short words, numbers or phrases into a 3D figure.

Image or silhouette

Use logos, shapes or depth maps as hidden figure.

Three optimized patterns

Choose dots, colors, or geometric patterns for a clearer 3D effect.

Depth control

Adjust the strength, spacing, and direction of the relief effect.

Guide points

Add visual guides to make it easier to focus on the stereoscopic image.

PNG and JPG

How to create a tridimania

1
Choose Text or Image and define the figure you want to hide.
2
Select points, colors or a geometric pattern.
3
Adjust the 3D strength and spacing until you get the relief effect you want.
4
Generate the autostereogram, check the effect, and download as PNG or JPG.

Text, silhouettes and depth maps

Light silhouettes on a dark background work especially well for a clear figure. You can also turn off silhouette mode and use an image’s shades of gray to represent different depth levels.

No AI or server required

This first version creates the depth map and autostereogram using Canvas directly on your device. You can experiment with patterns and depth without uploading your images.

Frequently asked questions

What is an autostereogram?

It is an image with a repeating pattern that contains depth information. Relaxing your eyes and focusing behind the image may reveal a hidden 3D shape.

Can I create a tridimania from text?

Yes. Write a word, number or short sentence and the tool makes it a depth map to generate the 3D effect.

Can I use a logo or a picture?

Yes. You can upload PNG, JPG or WebP. For logos and simple figures you can activate the silhouette mode; for depth maps you can keep the shades of grey.

What does inverting depth mean?

Change which areas appear to come forward or recede. This is useful when a shape’s depth looks reversed.

What are the guiding points for?

These guides help your eyes converge correctly. Relax your gaze until you see a third dot between the two dots in the image.

Are the images uploaded to a server?

No. The generation is done locally by means of Canvas in your browser.
