Grain Filter
Add a film-grain texture to an image. Upload an image, adjust the grain intensity, and download the result.

Pro Tips
- •Grain is added as random per-pixel noise, similar to the texture of analog film photography
- •Higher intensity values produce a more pronounced, gritty texture, while lower values add a subtle finish
- •Adding grain can also help disguise banding artifacts in smooth color gradients
- •The whole file is processed locally in your browser - nothing is uploaded anywhere
Most Popular
Most users use a moderate intensity around 20-40% for a subtle vintage texture
When to Use This Tool
Add a nostalgic, analog film texture to a digital photo.
Use grain to add atmosphere and a tactile feel to an otherwise flat, clean image.
Break up visible color banding in smooth gradients by adding a layer of fine noise.
Add a gritty texture as a stylistic element in a design or social media post.
How It Works
Read the uploaded image and decode it using the browser's native image support
Add random noise to each pixel's color channels, scaled by the selected intensity
Draw the noisy pixel data onto a new canvas
Encode the canvas as PNG, ready to preview and download

Frequently Asked Questions
Does this add real film grain characteristics?
This tool adds uniform random noise, which approximates the look of film grain but doesn't replicate the specific chemical grain patterns of actual analog film stocks.
Will grain make my file size larger?
Yes, slightly. Random noise reduces how well PNG compression can predict pixel values, so grainy images typically compress to a somewhat larger file size.
Is my image uploaded to a server?
No. The entire process runs locally in your browser using the Canvas API. Your image never leaves your device.
What format is the output?
The result is downloaded as a PNG file, which preserves any transparency in the original image.
Can I remove grain from a photo instead?
This tool only adds grain. Removing existing noise requires denoising algorithms, which are a different kind of processing not covered by this tool.
