Add Noise to Image Tool - Free Grain and Film Grain Online
Our add noise image editor helps you create texture, grit, and analog character in seconds. Choose between Gaussian, Uniform, Salt & Pepper, Film Grain, and Monochrome modes, then fine-tune intensity and grain size. Everything runs in your browser for fast and private editing.
Five Noise Algorithms
Switch between smooth sensor-like grain and stylized speckle effects without leaving the page. Use Gaussian for realistic photo texture or Salt & Pepper for high-contrast static looks.
Intensity + Grain Size Control
Dial subtle micro-noise or coarse chunky grain with two sliders. For block-style censoring instead of grain texture, try our pixelate image tool.
Film Grain Simulation
Film Grain mode adds luminance-weighted texture, so midtones carry more grain while extreme shadows and highlights stay cleaner for a natural analog feel.
Creative Filter Stack Ready
Grain pairs well with posterize image and sepia filter workflows for vintage and editorial styles.
Private In-Browser Processing
Your image is processed locally via Canvas API. No uploads needed for noise generation, so sensitive images stay on your device.
Format Flexibility
Export as PNG, JPG, or WEBP. If you want monochrome styling after adding texture, use black and white filter or grayscale image.

Frequently Asked Questions About Add Noise to Image Tool
Learn how to add grain and noise online, choose the right noise type, and export high-quality noised images.
How do I add noise or grain to an image online for free?
Upload your image, choose a noise type, adjust intensity and grain size, then download. The preview updates in real time so you can fine-tune before export.
What is the difference between Gaussian, uniform, and salt and pepper noise?
Gaussian noise follows a bell-curve distribution and looks more natural. Uniform noise spreads random variation evenly. Salt and pepper noise creates sparse black and white speckles for a static-like effect.
How do I make a photo look grainy like film?
Use Film Grain mode with moderate intensity and a small grain size. Start around intensity 15 to 35 and grain size 1 to 3, then adjust to match the look you want.
What is film grain and how is it different from digital noise?
Film grain is a texture associated with analog film stock and often appears more organic in midtones. Digital noise usually comes from sensor limitations and may look harsher or more color-biased.
How much noise should I add for a vintage look?
For subtle vintage texture, use intensity 10 to 25. For stronger stylized grain, use 30 to 55. Very high values are useful for creative effects but may hide fine detail.
Can I add noise to a PNG with transparency?
Yes. PNG files are supported. You can choose whether transparent pixels should be affected or left unchanged by using the transparent-pixel option.
Does adding noise reduce image file size?
Not usually. Noise often increases visual complexity, which can make compressed formats less efficient. If file size is important, export as JPG or WEBP and tune quality settings.
How do I add noise in Photoshop versus online tools?
Desktop apps offer advanced layer workflows, but online tools are faster for quick edits. This page gives immediate browser-based controls for noise type, intensity, grain size, and export format.
Is my image uploaded to a server when I add noise?
No. Processing is done locally in your browser using Canvas. Your image does not need to be uploaded for noise generation.
What if I want to remove grain instead of adding it?
Noise and grain removal is a different workflow. If your goal is cleanup, use a denoise or restoration tool rather than adding grain filters.
