Workflow & Usage
-
Add your images Drag & drop, paste, or click to select JPEG, PNG, or WebP files. You can work with a single image or process many at once.
-
Adjust grain amount Use the Grain Amount slider to control intensity:
- Low values add subtle texture
- Mid values create a classic film look
- High values produce strong, gritty grain
-
Preview instantly Each image card shows a live preview using a fast, downscaled canvas. Grain is applied directly to pixel data so you see real texture — not an overlay.
-
Select your batch Include or exclude images, remove items you don’t need, and track export progress visually.
-
Export your results
- Download images individually
- Export all selected images as a ZIP
Files keep their original format and use clear names like:
photo-film-grain.jpg
Everything runs fully on-device and offline-friendly.
Use Cases
-
Photography & Portfolios Add subtle texture to digital photos for a more organic, analog feel.
-
Cinematic & Editorial Images Create moody visuals inspired by film stock and classic cinema.
-
Social Media & Thumbnails Break the “too clean” digital look with tasteful grain.
-
Brand & Visual Identity Apply consistent grain across a full image set for a cohesive style.
-
Creative Experiments Push grain strength for raw, gritty, or lo-fi aesthetics.
Tips for Best Results
-
Midtones benefit most from grain. Images with balanced light and shadow show the most natural texture.
-
Avoid max grain for portraits. Subtle settings preserve skin detail while still adding character.
-
Batch consistently. Apply the same grain amount across multiple images to keep a unified look.
-
Pair with optimization tools. After exporting, run your images through Image Compressor or Progressive JPEG Converter for web-ready file sizes.
How It Works
-
Luminance-aware grain Each pixel’s brightness is analyzed so grain appears stronger in midtones and softer in highlights and shadows — mimicking real film behavior.
-
Gaussian noise generation Grain is created using normally distributed noise instead of uniform randomness, producing a more natural texture.
-
Direct ImageData manipulation Grain is applied directly to pixel data on a canvas — no overlays, no CSS tricks.
-
Fast previews, full-quality exports Previews use downscaled canvases for speed, while exports run at full resolution for maximum quality.
-
EXIF-aware loading Images are loaded with
createImageBitmap({ imageOrientation: 'from-image' })to preserve correct camera orientation.
