Frequently Asked Questions

Does PNG compression remove transparency?
No. PNG output keeps alpha transparency. Choose PNG when you need see-through backgrounds or crisp flat graphics.
Why is my PNG file still large?
PNG is lossless and best for graphics, not photos. For photographic images, try WebP or JPEG for much smaller files.
Can I compress PNG to WebP?
Yes. Select WebP as the output format to dramatically reduce size while often keeping transparency support.
Is PNG compression lossless?
PNG itself is lossless. Re-encoding at maximum quality preserves pixels; lower quality settings apply lossy conversion if you change format.
