Frequently Asked Questions
How to compress a PNG file?
Upload your PNG file and choose a smaller maximum width. PNG ignores the quality control because it uses lossless encoding; dimension reduction is the available size-control path.
Can I compress PNG without losing quality?
PNG output uses lossless encoding, but re-encoding can be the same size or larger. Reducing dimensions removes pixels, so it is not lossless. Convert to WebP when a smaller lossy output is acceptable.
How much can I reduce PNG file size?
By reducing dimensions, you can typically achieve 30-70% size reduction. For example, scaling a 4000px wide image to 1920px can reduce file size by 75% or more.
What is the best way to compress PNG for web?
For web use, resize your PNG to the maximum display size needed. A 1920px wide image is usually sufficient. Alternatively, convert to WebP for 25-34% better compression.
