Image Noise Generator
Add grain or color noise to any photo for a film or analog look.
Adds per-pixel random offsets to RGB values, producing a grain or noise texture. Toggle monochrome for an authentic film-grain feel, or keep color noise for digital sensor look. Adjustable intensity from 0 to 120.
Common use cases
- Add film grain to photos for an analog 35mm aesthetic
- Roughen up sterile UI screenshots for editorial spreads
- Mask compression artifacts in low-bandwidth images
- Generate noise textures for design overlays and backgrounds
Frequently asked questions
What's the difference between mono and color noise?▾
Monochrome adds the same random offset to R, G and B per pixel — that's classic film grain. Color noise picks independent offsets per channel, which looks like digital sensor noise.
Will it work on transparent PNGs?▾
Yes. The alpha channel is preserved untouched; only RGB pixels get noise.
Why is my output much larger than the original?▾
Random pixel variation defeats compression. Noisy PNGs are big — re-export as JPEG quality 0.85 with our image compressor for a smaller file.
