What is sepia?

Sepia is a warm brown tone derived from cuttlefish ink (Sepia officinalis). In photography, sepia refers to the brown tint of antique photos that oxidised over time. Digital sepia is a filter that converts greyscale values to warm brown tones.

How to use the sepia tool

Upload your PDF to the sepia tool. It converts colours to sepia tones: black becomes dark brown, white becomes cream, greys become warm brown-grey tones. The result has the appearance of an old document or antique photograph.
