Frequently Asked Questions
What is lossy PNG compression?+
Lossy PNG compression (like pngquant) reduces the color palette to 256 colors. For most graphics and screenshots this is invisible, but it can affect smooth gradients.
Should I use lossless or lossy PNG compression?+
Use lossless for images that need pixel-perfect accuracy (icons, logos). Use lossy for screenshots and UI images where a small color reduction is invisible.
