Common questions
Good to know
Answers specific to this tool and its current capabilities.
How does this PNG optimizer reduce file size?+
It decodes and re-encodes the visible pixels, which removes ancillary metadata and can produce a cleaner file.
Will PNG transparency remain after optimization?+
Yes. The re-encoded PNG retains its alpha channel and transparent regions.
Why might an optimized PNG stay nearly the same size?+
Complex pixel data or an already optimized source can leave little room for browser re-encoding to improve.
