Lossless PNG optimization
PicBrewery uses oxipng for PNG output — lossless DEFLATE recompression, palette quantization where applicable, and metadata stripping. Visual pixels do not change.
Screenshots and UI assets with flat colors often shrink 20–50%. Photographic PNGs (rare but possible) may see smaller gains because PNG is the wrong codec for photos.

자주 묻는 질문
Is PNG compression lossless in PicBrewery?
Yes — oxipng recompresses PNG without changing pixels. What you see is what you get.
Will transparency survive?
Yes. Alpha channels are preserved in the PNG output.
Why is my PNG still large?
PNG is lossless — photographic content belongs in JPEG, WebP or AVIF. If you need smaller files and can accept lossy compression, check the WebP or AVIF columns.
EXIF가 남나요?
No; metadata is stripped during optimization.
Can I batch-compress PNGs?
Yes — up to 20 files per batch with ZIP download.
