This free tool adds realistic noise to an image in three flavors. Mono is the classic grainy static: the same random brightness shift lands on every color channel, which keeps the photo's colors honest while making it visibly textured. Color gives every channel its own randomness, the look of a high-ISO digital sensor or analog TV static. Film grain is different from both: soft, slightly clumpy grains that concentrate in the midtones and stay out of deep shadows and bright highlights, the way grain behaves on real film stock. Pick a type, drag the strength slider, and the preview updates live.
Drop in a photo, choose Mono, Color or Film grain, and set the strength - 10 to 25 reads as subtle texture, 30 to 50 as a deliberate effect, and everything above as heavy static. Download as PNG for a lossless result, or as JPG or WebP for smaller files. Everything runs in your browser: the image is never uploaded, there is no signup, and no watermark is added.
Noise is one of the quickest ways to give a clean digital image some character: a vintage or documentary mood, a lo-fi aesthetic for social posts, or a film-photo feel on renders and AI-generated images that look suspiciously smooth. It is also a practical fix - smooth gradients like skies and studio backgrounds often show ugly banding stripes after compression, and a small amount of mono noise breaks the bands up so the gradient looks continuous again. Designers also use noised images as overlay textures for posters, album art and web backgrounds.
Mono (grayscale) noise shifts each pixel's brightness without touching its hue - the safest choice for portraits and anything where skin tones must survive. Color noise perturbs red, green and blue independently, producing colorful speckle that reads as electronic: sensor noise, VHS static, glitch aesthetics. Film grain is not per-pixel at all: real grain forms small soft clusters, and its visibility follows the exposure - strongest in the middle tones, nearly absent in blacks and whites. This tool reproduces that, and it sizes the grains relative to the image, so a phone photo and a 40 megapixel scan get the same visual grain, not the same pixel count.
The preview responds to the slider instantly, and the download applies your exact settings to the full-resolution image - every pixel processed on your device through the canvas API, nothing sent to any server. The tool works offline once the page is open. For the opposite job - smoothing or softening an image - see the dreamy effect; for plain black and white conversion there is the black and white converter.
Open the image, pick a noise type and drag the strength slider until it looks right - the preview shows the look you are choosing. Then download in PNG, JPG or WebP at full resolution, where the noise is regenerated over every pixel of the original: film grain matches the preview exactly, while mono and colour grain come out finer on a large photo, because each speck is one real pixel. No account, upload or watermark is involved.
Choose the Film grain option. Unlike pixel static, it builds soft grain clusters that concentrate in the midtones and spare the deepest shadows and highlights, which is how grain looks on real film. The grain size scales with your image, so the effect looks the same whether the photo is 1 or 40 megapixels.
Grayscale (mono) noise shifts each pixel's brightness equally across all channels, so colors stay true - best for portraits and subtle texture. Color noise randomizes red, green and blue separately, giving the colorful speckle of high-ISO sensors and TV static.
Yes - that is a standard trick. Visible banding in skies and smooth backgrounds comes from too few tone steps, and a low strength of mono noise (around 5 to 15) dithers the steps apart so the gradient reads as smooth again.
No. The noise is generated and applied entirely in your browser on your device, at preview and at full download resolution alike. Nothing is transmitted, and the tool keeps working offline once the page is open.
Not here - this tool processes still images (PNG, JPG, WebP and other picture formats). For a video, export a frame as an image to test the look, or use a video editor's noise filter for the clip itself.
