Questions
How are centimetres and inches converted to pixels?
We use the DPI you set (300 by default, which suits printing). For example, 3.5 cm at 300 DPI is about 413 pixels.
What do the fit options mean?
Stretch forces the exact size. Contain keeps the whole picture and adds a background. Cover fills the size and crops the edges.
Can I keep the proportions?
Yes. Turn on "Keep aspect ratio" and change either the width or the height.
