- Photographers adding repeatable texture to static images
- Worth noticing
- Animated formats are rejected rather than silently flattened, and JPEG orientation metadata is applied during decoding.
Field notes
The editor accepts static PNG, JPEG, and WebP files up to 20 MB, 12 megapixels, and 8,000 pixels per side; animated formats are rejected. Grain intensity, texture scale, color mode, and a repeatable seed can be adjusted before export, with PNG transparency preserved or JPEG flattened onto white. The page explicitly distinguishes its deterministic synthetic noise from film-stock simulation, and notes that fine grain may be harder to judge in a scaled preview.
