Understanding add noise

Added noise introduces random tonal or colored variation across a picture.

Check a smooth area and keep the noise scale consistent with the final display size.

A practical workflow

  1. Choose the required source files, if any. Files are handled as stated in the workspace privacy label.
  2. Set the available controls and apply the operation.
  3. Compare the actual output, check its dimensions and download the generated file.

Decisions and limitations

  • Strength (%)
  • Radius or pattern size (pixels)
  • Pattern seed

16 megapixels maximum. Artistic treatments are algorithmic approximations with adjustable settings. Exported PNGs are flattened. For two-image operations, the second image must match the first image dimensions.
