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?
Reducing dimensions can lower file size, but the result depends on image content, original encoding, output format, and quality. Compare the displayed output before downloading.
What is the best way to compress PNG for web?
For web use, resize the PNG to the largest dimensions the page actually displays. You can also compare PNG and WebP outputs; the smaller format varies with the image.
