Add Noise to Image Online Free
Runs 100% in your browser — your files never leave your device.
Add film grain to a too-clean digital photo, give a flat graphic some texture, or match the grain of a reference image. The noise strength controls how pronounced the speckle is. The grain is generated and applied entirely in your browser.

About this tool
How the added grain works
The noise filter sprinkles random brightness variation across the image at the strength you set. At low strength it reads as film grain — a fine, organic texture; at high strength it becomes static, the way a detuned screen looks.
When to reach for it
Give sterile digital photos an analog feel, match a new image to the grain of a scanned reference, texture flat graphics and gradients so they band less, or make composites feel like single photographs.
Tips for the best result
Grain reads most naturally at low strength on photos, and heavier on flat graphics. Adding noise after posterizing breaks up the flat bands beautifully — texture over structure.
Frequently asked questions
Is added noise the same as film grain?
It is a close visual cousin. Real film grain varies with the stock and the development; the filter produces uniform random variation. At modest strengths, the eye reads both simply as texture.
Will the original file change?
No — the add noise effect is applied to a working copy in memory. Your original file stays untouched on your device, and the download is a brand-new file.
Which formats and sizes work?
JPG, PNG, and WebP files up to 50 MB. The result downloads in the original format with dimensions unchanged.
Does adding noise increase the file size?
Yes — random detail is the hardest thing to compress, so expect JPG and PNG files to grow. Add noise last, after all other edits, so the intermediate steps stay small.
