Guide to Resolution and High-Res

Selecting image resolution in AI Generator

In both the Essential and SD modes of AI Generator, you'll find resolution settings in the "Aspect ratio" section on the left side of the page.

Essential mode

In Essential mode, you can quickly select from a variety of preset aspect ratios:

1. Head to AI Generator.

2. Open the dropdown list in the "Aspect ratio" section.

3. You can choose from a wide range of aspect ratios (e.g., 1:1, 16:9, 4:5, etc.). Next to every option, you'll see the image's exact dimensions.

It's that simple! The tool will then generate images using the selected aspect ratio.

SD mode

SD (Stable Diffusion) mode offers more flexibility, allowing you to choose preset aspect ratios or set custom dimensions. To choose your own resolution:

1. Switch to AI Generator's SD mode.

2. You'll see a dropdown list similar to Essential mode but with an additional "Custom" option at the end. Select it.

3. Two input fields for width and height will appear below; enter your desired dimensions in pixels to set a custom resolution.

High-Res

Most models were trained on images with resolutions of 512x512 pixels or 768x768 pixels, and they don't always know how to behave when we try to generate bigger or smaller images. This most often manifests through images with duplicate people or objects.

The High-Res option allows you to generate images with double the resolution of the default settings, all while helping to avoid duplication. Using it will also slightly improve the details of your image—you can spot that difference at the end of the video below or in comparison at the end of this article.

Availability

You can't use High-Res in every mode and with every model. Take note of the following limitations:

• High-Res is only available in AI Generator's SD mode;

• it can't be used with models tagged with "XL" in the model selection menu (Stable Diffusion XL-based models);

• this feature only works with preset aspect ratios; it doesn't appear if you set a custom resolution.

Usage

To use High-Res, simply toggle this option before generating your image. Make sure you're using a non-XL model.

If you want to create an image with an even higher resolution, you can use an Upscale option. It recreates your original image with a 4x higher resolution. You can learn more about it in this guide and see its possibilities in the comparison below.

Comparison

Here is a comparison of the differences in images created using each feature mentioned earlier.

Default settings (512x512)

With High-Res (1024x1024)

Generated with default settings, then Upscaled (2048x2048)

Generated with High-Res, then Upscaled (4096x4096)

Below, you can view a zoomed-in version of the generated images. This will enable you to better examine any differences in quality.

Default settings (512x512)

With High-Res (1024x1024)

Generated with default settings, then Upscaled (2048x2048)

Generated with High-Res, then Upscaled (4096x4096)

We hope this guide helped you better understand Resolution and High-Res so that you can use these functions to your advantage while creating to your heart's content.

Frequently Asked Questions

What is image resolution in AI Generator?

Image resolution refers to the dimensions of the generated image, usually measured in pixels (width x height).

Can I use High-Res with any model?

No, High-Res is not compatible with XL models or when using custom resolutions. It’s specifically designed to work with non-XL models and preset aspect ratios.

Can I set custom resolutions in Essential mode?

No, custom resolutions are only available in SD mode. In Essential mode, you're limited to preset aspect ratios.
