Image noise is the fine, random grain that characterises analogue film and high-ISO camera shots. This tool adds it on purpose: each pixel gets a random brightness offset that is the same for all colour channels, so the colours are preserved and a monochrome grain appears.
Noise is useful for an analogue film look, to make smooth digital gradients livelier, to mask banding, or to give a graphic some texture. The amount controls how strong the grain is; at 0 the image is unchanged. The output keeps your original format and dimensions.
Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. The grain is monochrome (the same offset on red, green and blue), so the colour impression is preserved. Animated images are flattened to a single frame.

Limitations: Lays monochrome random noise over the image; the amount (0 to 100) scales the maximum per-pixel brightness offset. The same offset hits red, green and blue, so colours are preserved; 0 leaves the image unchanged. The original format and dimensions are preserved (PNG keeps transparency; JPEG flattens onto white). Animated inputs are reduced to a single frame.

No. The grain is monochrome - the same offset is applied to all channels, so only the brightness fluctuates locally and the colours are preserved.
For an analogue film look, livelier gradients, masking banding, and texture on smooth areas.
Yes. A PNG stays a PNG (with transparency), a JPEG stays a JPEG, and the dimensions are unchanged.
