How it works
- Drop a photo, several photos, or a whole folder.
- Choose a preset or adjust intensity and grain size.
- Apply it and download a file or a ZIP that keeps your folder structure.
Why the grain looks like film and not like noise
Film grain is not spread evenly over an image. It shows most in the midtones and fades in deep shadows and bright highlights. FolderPix follows that response, so skin and skies gain texture while blacks stay black.
The grain is built from pixel-level noise softened to the size you choose. This keeps it even across the image and avoids the faint grid pattern that scaled-up noise textures often leave.
Monochrome or color grain?
Monochrome grain changes brightness only. It is the discreet choice for portraits and fashion work, and it is the default. Color grain varies each channel separately, which gives a stronger look closer to high-speed color film.
Taking the digital edge off AI images
AI-generated images are often unnaturally smooth. A light grain, around 10 to 20, adds a surface for the eye to rest on and helps a series feel consistent. It changes the texture only: it will not fix anatomy or lighting.
Consistent grain across a series
A single look only works if every frame gets it. Tune the settings on one image and apply them to the entire batch. Each photo gets its own grain pattern, as frames on a roll do, with the same character and strength.
Questions
Are my photos uploaded?
No. The image is decoded and processed by your browser, on your device. FolderPix has no upload endpoint at all, and the site tells browsers to refuse connections to other servers. You can check it in the Network tab of your browser’s developer tools, or by going offline once the page has loaded.
Does adding grain reduce the resolution?
No. The output has the same pixel dimensions as your original. JPEG and WebP files are saved at 95% quality, and PNG stays lossless. Grain makes files heavier because fine detail compresses less well.
What intensity should I use?
Start around 12 for a barely visible texture, 25 for a clear film feel and 45 for a pushed, high-ISO look. Hover the photo to see the grain at actual size: the full preview is scaled to fit the screen, so it shows less grain than the file.
Is there a limit?
Single images are free and unlimited, and each batch can hold up to 10 images, with no account and no daily quota. Larger batches come with a paid plan or a one-time pack.
Is the result watermarked?
No. There is no watermark on any image.
