Before using the Img2Img tool, it is important to know what its usefulness is and how we can use it. Let’s explore practical scenarios where image-to-image generation can be a game-changer:

Imagine starting with an image and enhancing it with unique artistic styles. Whether you want to change colors, add or modify details, or apply various artistic effects, image-to-image generation makes it possible. You can create one-of-a-kind pieces of art by experimenting with different denoising strengths and styles.

2. Upscaling Low-Resolution Images

Do you have low-resolution images that need a boost in quality? Image-to-image generation is your solution. By specifying a higher resolution, you can upscale your images while maintaining or even improving their overall visual quality. This is particularly useful when you need larger images for printing or high-definition displays.

Denoising Strength
Denoising Strength

One of the most crucial settings in the Img2Img generation is the denoising strength. This setting determines how much the new image will resemble the original. It ranges from 0 (no change) to 1 (completely different). Striking the right balance between retaining the core features and introducing desired modifications is the key to success.

Denoising Parameters

For example, setting the denoising strength to 0.6 is a popular choice when you want to retain much of the original composition while adding details. This results in an image that maintains its core elements but with significant enhancements.

Resize Mode: Tailoring Your Canvas

Just Resize: This option stretches or shrinks your original image to fit the new canvas size.

Crop and Resize: It preserves the aspect ratio of your original image and crops it to fit the new canvas.

Resize and Fill: This setting adapts the original image to the canvas while filling any blank spaces with colors from the input image.

A Pro Tip: “Just resize” is suitable for most cases, while “Just resize latent upscale” is handy if you need to upscale the image as well.

Additionally, we’ll tick the “restore faces” option, retain the default resizing settings, and keep our dimensions unchanged. To add a touch of finesse to our output, we’ll set the denoising strength to 0.7 Simply you will practice all these things and you will be perfect. You will see the results by changing the settings yourself and will get your result based on denoising and prompts.

Sketch Tool: Draw anything and Replicate it into the Realism

If you are not a very good artist then don’t worry it will convert your bad drawing into a realistic image.

Sketch tool is an amazing experimental tool with the help of which we can draw anything on the canvas according to our imagination with color compositions and desired prompt and can generate realistic images using img2img stable diffusion.

  • Simply upload a white or black image into your canvas so that it will act as your background.
  • Then you draw something with colors, suppose you have drawn a painting.
  • Generate usage by adjusting the settings as per your requirement.

By dropping a white or black mask into the provided canvas, you can easily sketch out your ideas. This allows you to not only visualize your concepts but also add a personal touch to your work.

Pro Tip: You can add any elements to your images with the help of color tool and prompt.

Suppose for example you have a boy image in which you want to wear glasses, with the help of this tool, you can draw glasses with the simple color tool and give the prompt such as “man with yellow glasses” and it will generate as you want”

Inpainting: Target Edits


Sometimes, you might love the composition of your image but wish to alter specific details. In such cases, “In Paint” comes to your rescue.

It allows you to paint over the parts of the image you want to change. This feature is especially useful when you wish to retain the overall composition while making minor adjustments. This technique is especially useful when you want to focus on enhancing specific parts of an image while leaving the rest untouched.

It has its own settings in Inpainting, which are important to know if you want to use it properly.

Mask Blur: This setting controls the amount of blurring applied around your painted mask, influencing the softness or sharpness of the edges.

Mask Mode: You get 2 options here, one is “Inpaint Masked” which you can use when you want to make changes only in the painted areas and the other one is “Inpaint Not Masked” which can be used to make a slight change in the whole images.

Masked Content: In-Paint offers the “Masked Content” setting, which plays a pivotal role in generating the new image part. The “Fill” option uses the impainted area as a basis for generating new content. On the other hand, the “Original” setting keeps the base image unaltered while generating a new image. You can also opt for “Latent Noise” if you desire a completely different result or “Late Nothing” to blend colors from surrounding pixels.

Inpaint Area: It’s important to differentiate between “In-Paint Area” and “Mask Mode.” While “Mask Mode” determines what parts of the image are changed, “In-Paint Area” influences the inspiration source for the in-paint generation. Select “Whole Picture” if you want your painted area to seamlessly blend into the rest of the image. Alternatively, choose “Only Masked” to treat the masked area in isolation. You can also adjust the padding size to control the number of neighboring pixels used for inspiration.

Inpaint Sketch: Added Elements with Sketch

InPaint Sketch is a versatile digital tool that allows artists to manipulate images and transform them into unique and eye-catching pieces.

If you struggle to translate your creative ideas into a digital canvas, the “In Paint Sketch” tab is your artistic playground. You can effortlessly sketch out your vision by using a white or black mask and a paintbrush. Highlight the details you want to emphasize, add color, and pair it with your prompt to transform your sketch into a remarkable piece of art.

Please Don’t Confuse in Sketch Tool and Inpaint Tool

“Sketch tool” allows you to change the overall image but in “Inpaint tool” you can mask a particular area and change the same particular meshed area with the help of color and prompt.


Upscaling involves increasing the resolution of your images. This can be particularly handy when you have low-resolution images that need to be turned into high-resolution versions. By using the right denoising strength and settings, you can upscale your images while preserving their core features.
