About this tool
This tool overlays your photo with a randomised noise texture, letting you dial the intensity from a barely-there 5% fine grain up to a heavy 50% gritty texture reminiscent of pushed 35mm film or an old low-light photograph. A live preview updates as you move the intensity slider, so you can find the exact amount of grain that suits a retro poster, a moody portrait or a vintage-style social media post. Unlike a blurry filter, noise adds fine random detail rather than removing sharpness, which is what gives scanned film and old photographs their distinctive gritty character. The effect is generated per-pixel on an HTML canvas, so results are unique every time you regenerate them, and everything happens locally without your photo ever leaving your device. JPG, PNG and WebP files work as input, with PNG output preserving any transparency from the original image.

Why use this tool
Modern digital photos can look clinically clean, and adding grain is a quick way to give them the warmth and texture of analog film for retro posters, band promo shots or vintage-styled social content. Recreating this manually with layered noise filters in a design app takes several steps, while this tool applies an authentic-looking grain in one adjustment.
Tips & best practices
- Use a lower intensity (5-15%) for a subtle texture that still looks like a clean photo.
- Combine noise with a duotone or black-and-white conversion for a full vintage film effect.
- Regenerate the noise pattern a few times if you want a specific grain look with more or less clumping.
Common use cases
- Giving a digital photo a vintage 35mm film look for a retro poster
- Adding texture to a band promo photo for an analog aesthetic
- Styling a moody portrait with heavier film grain
- Making a smooth studio photo look like an old print for a nostalgic post
- Blending a new photo with archival images by matching their grain texture
Frequently asked questions
What's the difference between noise and grain?
The terms are often used interchangeably here; both describe adding random pixel-level texture that mimics analog film.
Will adding noise make the image look worse?
Used at a moderate intensity, it usually adds character and a vintage feel rather than degrading the photo.
Can I control how strong the grain effect is?
Yes, an intensity slider lets you choose anywhere from a subtle 5% texture to a heavy 50% gritty look.
Does the noise pattern change every time?
Yes, the noise is randomly generated, so regenerating gives a slightly different texture each time.
Does adding noise increase the file size a lot?
It can increase file size somewhat since noise adds high-frequency detail that compresses less efficiently.
