Frequently Asked Questions
Can I compress PNG without losing quality?
PNG output preserves the decoded pixels and removes original metadata. Browser re-encoding may produce a larger file; we keep the original PNG if it is smaller. No size reduction is guaranteed.
Does the quality slider affect PNG?
No. The quality slider applies to lossy JPG and WebP output. PNG remains lossless.
