How to Add Grain to a Photo
Add grain to any photo in seconds - no Photoshop, no account, no install. Grainy is a free browser tool that processes images locally on your device.
Step-by-Step Guide
Upload Your Image
Open Grainy and drag your photo onto the upload area, or click to browse. JPG, PNG, and WebP are all supported. Images larger than 4096px are automatically resized.
Choose Your Grain Style
Pick fine grain for a subtle film look, medium for visible texture, or coarse for a heavy analog feel. Use the intensity slider to dial in exactly how much grain you want.
Preview and Compare
The preview updates in real time as you adjust settings. Use the "Compare" button to toggle between the original and the grained version so you can see exactly what changed.
Pick Your Export Format
Choose JPEG for the smallest file size, WebP for a modern format, or PNG for lossless quality. JPEG and WebP include a quality slider for fine control over file size.
Download
Hit download and your grainy photo is saved to your device. The estimated file size is shown before you download - no surprises. Your photo never leaves your browser.
When to Add Grain to a Photo
Instagram and Social Media
A subtle grain effect makes photos stand out in feeds full of over-processed images. Fine grain at 20-30% intensity adds just enough texture to feel intentional.
Portrait Photography
Grain adds warmth and character to portraits. It softens the clinical sharpness of digital cameras and gives skin a more natural, film-like quality.
Black and White Photos
Grain is essential for convincing black and white conversions. Without it, digital B&W photos can look flat and lifeless. Medium grain at 40-60% works well.
Album Art and Posters
Heavy grain creates a raw, lo-fi aesthetic popular in album covers, gig posters, and editorial layouts. Coarse grain at high intensity delivers this look.
Why Use Grainy Instead of Photoshop?
Photoshop's “Add Noise” filter uses pure random noise that creates unnaturally large file sizes and doesn't look like real film. Grainy uses spatially-correlated noise that mimics actual silver halide grain - it looks more realistic and compresses far better.
Plus, Grainy is free, runs in your browser, and takes seconds instead of requiring a subscription and a learning curve.
