Realistic film grain with size, amount and roughness
Choose a file to start.
Imagera's film grain adder lets you add film grain to a photo online using a browser on a phone, tablet or computer. This photo grain adder gives photographers and designers control over the strength, size and unevenness of simulated grain. Choose a JPG, PNG, WebP or HEIC image, adjust the texture and compare it with the original. The grain is calculated on your device without uploading the picture for processing. 2 free downloads, 8 more after sign-in.
Published · Updated · by the Imagera teamImagera is a browser-based AI studio for images, video, music and voice, so you do not need a separate app and account for every model. Pricing is credit-based: one balance covers every tool, and each job shows its credit price or estimate before you run it.






















Recorded results from this tool. Results vary with the source image, settings and device. Drag each handle to compare.






Grain changes 3 color channels while leaving opacity alone. The texture can alter the surface of a cutout without filling its transparent surroundings.
A 2000 × 1500 picture has 3 million pixels before and after grain, if it fits the browser’s canvas limits. Adding texture does not add resolution.
The local grain generator uses 1 fixed starting seed. Reprocessing the same decoded image with the same settings repeats the texture; it does not generate a new scene.
Try Real Film GrainAmount controls how strongly the texture shows. Grain size changes the scale of the specks, while Roughness changes how unevenly they gather. A stronger effect does not have to mean larger specks.
The starting values are 35% for strength, 2 for size and 50% for roughness. Treat these as a starting point, not a recipe for every picture. Change one slider at a time so you can tell which part of the texture you prefer.
For a subtle portrait finish, lower the strength and keep the specks small. Compare the face, hair and smooth background before increasing the effect. If the texture draws attention away from the expression, ease it back.
Inspect the picture both close up and at its intended viewing size. This tool adds texture to the existing image; it does not repair skin detail, remove existing noise or sharpen a soft face. A noisy source can become busier when more texture is added.
The effect is weighted toward midtones and reduced near the darkest and brightest areas. It is not a flat texture pasted at equal strength over the whole frame. Very dark and bright areas can still receive grain.
Leave Color grain off for brightness texture without extra colored speckles. Turning it on adds small differences between the color channels. The switch does not convert a color photo to black and white; use a monochrome source if that is the finish you want.
Finish any resizing before adding your final grain treatment, then check the saved picture at its intended display size. Fine texture can look different when another app scales or compresses the file. Increasing strength alone is not always the answer; compare the size of the specks too.
The grain pass keeps the working canvas dimensions, but very large originals may be reduced to fit the browser. The export type is chosen automatically and can differ from the source. Some outputs use lossy encoding, so unchanged dimensions do not mean an unchanged file or lossless quality.
The browser reads the photo and generates the texture locally. This grain operation needs no image-generation model or remote image-processing request. The page still loads code and makes service requests, including error reporting when processing fails.
The grain texture is drawn on a canvas, so your phone, tablet or desktop browser must support that drawing step. Large pictures need more memory, and processing time depends on the device. If the grain pass fails on a large photo, retain the original and apply the texture to a reduced copy.
Grain can give a clean image a textured finish, but it does not recreate a particular film stock, relight a subject or fix an implausible shape. There are no dust, scratch, light-leak or film-border controls here. Use Photo Filters for a separate color treatment.
The linked Real Film Grain studio also offers an AI Image Humanizer for broader realism edits. Its humanizer can repaint image content, while its separate grain option targets the surface. Choose the operation deliberately when the original composition needs to stay intact.
Add a JPG, PNG, WebP or HEIC picture after making any crop or size changes you need.
Adjust Amount, Grain size and Roughness. Find Color grain in Advanced for colored speckles.
Run the grain effect, then move the comparison slider across faces, skies and other smooth areas.

Open the picture in this grain adder, set the strength and texture, then run the effect. Compare the result with the source before saving your edited copy.
Begin with low strength and small specks, then inspect the face at the size people will view it. Reduce the effect if texture starts to compete with eyes or hair. There is no single setting that suits every portrait.
Grain size changes how large the texture appears. Roughness changes its unevenness by mixing in coarser variation. You can keep specks relatively fine while giving their distribution more variation.
This effect is simulated noise shaped into a film-like texture. It smooths the generated field, adds uneven clumps and varies strength with brightness. It is neither captured film grain nor a measurement of the noise from a particular camera.
Yes. Keep Color grain disabled to add matching brightness changes across the channels. Enabling it can introduce colored speckles into an otherwise monochrome image.
The grain strength follows the brightness of the source pixel, with the strongest weighting in the middle tones. It tapers near either extreme but does not completely switch off there.
Here the texture is written into the result pixels before encoding. Compare the saved file at the same zoom as the preview; scaling and compression elsewhere can make fine specks less visible. For a smaller delivery image, resize first and apply grain to that copy.
Use a mobile browser with canvas support and choose the picture from your device. A desktop browser uses the same processing path. Available memory can limit how large a photo the browser handles.
The grain engine processes the selected file inside the browser. It does not send the picture to a processing server. Network activity for loading the website is separate from editing the photo.
The effect itself does not resize the working image. The image loader can shrink an oversized original to meet device limits, so check the output dimensions before using it in a large layout.
No. The grain operation changes color values without changing opacity, and supported transparent inputs use an output that retains transparency. Empty areas stay see-through rather than becoming a solid grain background.
JPG, PNG, WebP or HEIC. Phone photos that need conversion use a local conversion path before processing. The saved file type is selected automatically; there is no export-format picker in this grain tool.
The generator starts from a fixed seed, so an identical decoded image and settings give a repeatable texture. Changing the image dimensions or grain controls can change the pattern. Adding an already edited file again applies another grain pass.
Those effects are outside these controls. You can shape the grain, but the tool has no film-stock profiles or overlays for scratches and light leaks. A full vintage treatment needs separate color and finishing edits.
It can change an overly smooth surface, but lighting and scene details remain as they were. For broader changes, the related studio offers a humanizer that may repaint parts of the picture. Review those changes against the original.
This page takes a still image. It does not read a video timeline or generate changing grain across frames. Use a video editor when the texture needs to move with footage.
