Question 1

How does PNG optimization work?

Accepted Answer

PNG is a lossless format, so there's no quality slider. Optimization works by stripping unnecessary metadata (EXIF, color profiles) and re-encoding the image data more efficiently.

Question 2

Will optimizing a PNG reduce quality?

Accepted Answer

No. PNG optimization is lossless — the image will look identical to the original, pixel for pixel. Only metadata and encoding efficiency change.

Question 3

How much smaller will my PNG be?

Accepted Answer

Results vary depending on the original file. Images with embedded metadata or inefficient encoding may shrink by 10-30%. Already optimized PNGs may see little change.

Question 4

Are my files uploaded to a server?

Accepted Answer

No. Optimization happens entirely in your browser. Your images never leave your device.
