How to Use the Noise Image Generator
The Noise Image Generator lets you customize rough noise and film-style grain, then save the result as a PNG image. You can create noise images on solid or transparent backgrounds, or upload your own image and apply a noise or grain effect.
1. Choose a template
Click “Choose Template” to select one of the preset noise and grain designs.
Templates range from fine noise to film-style grain, making it easy to choose a look you like and then fine-tune each setting.
Changing the template does not reset your uploaded image or output size settings.
2. Choose noise or grain
Select “Noise” or “Grain” under “Type.”
Noise creates a sharp texture from small, randomly placed particles. It works well when you want to add a subtle roughness to a photo or image.
Grain creates a softer texture inspired by the particles found in film photography. It works well when you want to give a photo or image a film-like appearance.
3. Choose a background
Choose “Color,” “Transparent,” or “Image” for the background.
“Color” creates a noise image using the background color of your choice.
“Transparent” saves only the noise or grain as a transparent PNG. This is useful when you want to overlay the generated texture in a web design or image-editing application.
“Image” lets you upload your own image and add a noise or grain texture to it. The selected image is processed in your browser and is not sent to or stored on a server.
4. Adjust the noise or grain
Use “Color Mode” to switch the particles between monochrome and color.
When using a solid or transparent background, choose any particle color under “Grain Color.”
“Strength” controls how visible the noise or grain appears. Lower values produce a subtle texture, while higher values make the noise more pronounced.
“Grain Size” changes the size of the particles that make up the noise or grain. Use a lower value for a fine texture or a higher value for a coarser, more prominent texture.
“Density” controls how many particles are shown. Lower values create a sparse pattern, while higher values spread more particles across the image.
Click “Regenerate” to change only the particle arrangement while keeping your current settings.
5. Check the preview
Your settings appear in the preview in real time.
Switch between “Before” and “After” to compare the image before and after processing.
Adjust the strength, grain size, density, and other settings until you achieve the texture you want.
6. Download the PNG image
Enter the output width and height under “Output Image Settings,” then click “Download PNG” to save the image.
When you upload a background image, the output width and height automatically change to match the original image dimensions. If you change either the width or height, the other value updates automatically to preserve the original aspect ratio.
Noise vs. Grain
Noise and grain both add a rough texture to an image, but they differ slightly in appearance and common use.
Noise
Noise is a sharp texture made from small, randomly placed dots or pixels.
Adding a small amount of noise to a solid color or gradient can reduce the flat, overly digital appearance of the design.
It is well suited to website backgrounds, banners, gradient backgrounds, and other designs that need a subtle texture.
Grain
Grain is a softer, more organic texture inspired by the particles visible in film photography.
Adding it to a photo or illustration can create a film-like atmosphere or a slightly retro appearance.
It works well for photo editing, social media graphics, posters, featured images, and more.
Tips for Creating Noise and Grain Textures
Noise and grain often look more natural when applied subtly rather than at maximum strength.
For a website background or gradient, use a low “Strength” and a small “Grain Size” to create a fine texture that does not distract from the design.
For a film-style appearance, select “Grain” and use a slightly larger particle size to make the texture easier to see.
Even when you want a prominent texture, try adjusting “Density” and “Grain Size” along with “Strength.” Combining these settings gives you a wider range of effects.
FAQ
What is the difference between noise and grain?
Noise consists of fine, sharp, randomly placed particles, while grain is a softer particle texture inspired by film photography.
Noise is recommended for adding fine texture to a web background, while grain works well for giving a photo a film-style appearance.
Can I create a noise image with a transparent background?
Yes. Select “Transparent” under “Background” to save the noise or grain without a background as a PNG image.
Can I add noise or grain to my own image?
Yes. Select “Image” under “Background,” upload an image, and then apply either noise or grain.
Is my uploaded image stored on a server?
No. The selected image is processed in your browser and is not uploaded to or stored on a server.
What is the difference between Monochrome and Color modes?
In Monochrome mode, the same brightness variation is applied to all particles, allowing you to add natural-looking noise or grain while preserving the original colors. In Color mode, different variations are applied to the red, green, and blue channels, creating a digital-noise effect with colored particles. Monochrome is recommended for adding a natural texture to photos and images, while Color is better for creating more colorful, stylized noise effects.
Can I change only the particle arrangement?
Yes. Click “Regenerate” to change the particle arrangement while keeping settings such as strength, grain size, and density.
Can I use the generated images commercially?
Yes. You may use noise and grain images generated with this tool for commercial purposes, and no credit is required.
If you upload and edit an existing image, you must follow the original image’s license terms and copyright restrictions.
