Photo grain generator.

Monochrome grain is closest to the silver halide crystals of black-and-white film. For color film use color-matched grain at 10 to 20 percent: the grain of a color negative follows the picture's own colors rather than adding random ones.

8 to 15 percent. The photo still reads as clean but gains a tactile depth. Above 25 the grain becomes a visible choice rather than a texture.

Kodak Portra: color-matched at 8 to 12, in color. Tri-X: monochrome at 18 to 25 with black and white on. CineStill 800T: film grain at 15 to 20, in color. Ilford HP5: monochrome at 20 to 30 with black and white on.

After. Finish the color grading, exposure and crop first and add grain last, or later edits will stretch and smear the specks.

Sampled grain reads the photo's own palette and builds the specks from it, so the texture looks native to the picture rather than laid over it.

Film grain scatters random colored specks, like expired color film. Monochrome grain is gray only, the silver halide look. Color-matched grain nudges each speck a little away from the pixel's own color, so it blends. Sampled grain reuses colors found elsewhere in the photo, and tinted grain uses one color you pick.

The amount is the share of pixels that get a speck. 8 to 15 percent adds texture you feel more than see; 20 to 40 is visible film character; above 50 it reads as damaged or experimental film.

Each pattern is random, and no two frames of real film share one either. Click New pattern until the specks fall where they suit the photo; the same amount and style keep a series consistent even though every pattern differs.

No. The file is decoded, drawn and re-encoded by your browser's canvas, and the page makes no request with it. You can load the page, go offline and keep working; nothing is stored either.

No. The Photo grain generator is free and opens without a sign-in, an account or an install.

Nothing. The Photo grain generator holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.

The Photo grain generator is one of 44 in its group. The group's page, /tools/jpg, lists them all.

The tool is free. Its interface is built from shadcn.io's own components (Button, Input, Slider and the rest of the registry under /ui), which come in React, Vue, Svelte and Solid. Pro adds the blocks and templates for the product around it.
