🎛️ Photo Grain / Noise Generator
Add film grain, monochrome noise, or colored texture to photos locally in your browser with before/after preview and download.
Fine monochrome grain for portraits, product shots, and clean editorial crops.
Choose a photo to start. Grain and noise generation runs locally in this browser.
Why it is useful
It is useful for making clean digital photos feel less sterile, matching a film-inspired campaign, adding texture to thumbnails, or preparing gritty editorial graphics without opening a heavy editor.
How it works
The selected image is decoded locally, drawn to a canvas, then each pixel block receives seeded monochrome or RGB noise blended with the original image.
Best input
Use a sharp, already-edited image. Apply grain after cropping and color correction so the texture matches the final exported size.
Style controls
Start from a preset, then tune grain mode, intensity, grain size, blend, seed, contrast lift, and export format for the final copy.
Privacy note
Image processing is browser-local. The page does not intentionally upload selected images or save them to a server.
Important limitation
Canvas exports can remove metadata, flatten animated images, and shift color profiles. Grain is a creative texture effect, not a photo restoration or denoising tool.
Quick answers
Does this upload my photo?
No. The grain effect uses local browser APIs and Canvas processing.
What is the seed for?
The seed changes the repeatable noise pattern so you can regenerate a similar texture or choose a different grain layout.
Common Use Cases
Add subtle film grain to a portrait
Use Subtle Film with low intensity to soften a clean digital portrait without obvious texture.
Create a gritty editorial crop
Use Gritty Documentary with larger grain and higher blend for a street-photo or zine-style image.
Texture a social thumbnail
Use Lo-fi Poster color grain to give flat graphics and promo images a more tactile feel.

Move between vintage, duotone, noir, vignette, grain, cinematic color grade, and background blur effects while keeping selected image pixels local to the browser.
