Frequently asked questions

Can PNG files be compressed without losing quality?
PNG is lossless, so re-encoding cannot reduce visual detail — but stripping metadata and resizing can shrink files meaningfully.
Why is my PNG still large after compression?
For the biggest savings, resize large PNGs or convert to WebP. Lossless PNG optimization needs a tool like oxipng or pngquant (for quantized color).
Should I compress PNG or convert to WebP?
For the web, converting to WebP usually saves far more space. Keep PNG when you need lossless quality or transparency in legacy apps.
