The short answer
Why use Dithering?
A focused effect tool is faster than opening a full editor when you already know the look you need. The amount control makes it easy to stop before texture and detail disappear.
Dithering focuses on applying an adjustable dithering treatment to a copy of an image. Filters work on decoded image pixels and write a separate output. The preview is the place to judge edges, skin tones, and any text inside the image.
The selected file stays in this browser tab and is released when you leave the page. The effect is applied to a new copy. Inspect detailed areas at full size because a strong setting can hide texture or introduce banding.
What Dithering does
Open the source photo
Drop, choose, or paste a supported file into Dithering. Applying an adjustable dithering treatment to a copy of an image. The source stays on your device; we work on a copy.
Apply the treatment
Dithering is for applying an adjustable dithering treatment to a copy of an image. The preview is the place to decide if the setting went too far. The original file is not overwritten.
Useful controls
Main controls: Effect amount, plus a color choice for effects that need one. Working limit: 50 MB and 50 megapixels per image. Watch the preview at full size before you save. A current desktop browser usually has more memory than a phone.
Download a copy
Export is a flattened png or browser-supported raster image. The download is a new file. Keep the original until you have opened the copy once.
Where Dithering fits
These are ordinary jobs where the focused controls save time. They also show where a full editor or a manual review may still be the better choice.
Style tests
Try Dithering on a finished layout before rebuilding the design around it.
Social graphics
Give a photograph a consistent treatment without changing the source file.
Readability checks
See whether a simplified tonal treatment makes overlaid text easier to read.

Before you export
- Start near the middle, then move the amount in small steps.
- Judge faces and smooth gradients carefully; heavy effects show artifacts there.
- Compare the result at the size where it will actually be used.
- Save a new copy instead of running several destructive passes on one export.
