Frequently Asked Questions

What counts as a 'border' to trim?

Pixels with alpha < threshold (transparent) or all RGB channels > 255-threshold (near-white) are considered background border and removed.

Will it trim content from my image?

Only if the content itself is near-white or transparent at the edge. Reduce the threshold slider to make trimming less aggressive.

Does it trim all four sides?

Yes — top, bottom, left, and right are all trimmed independently.
