.pngfile (or several) on the drop zone. - Wait for the results row. The PNG column is oxipng-optimized — same pixels, fewer bytes.
- Download from the PNG cell or use Download all as ZIP.
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.
Millal WebP või AVIF võidab PNG
Veebi jaoks on lossy WebP/AVIF alfaga sageli palju väiksem kui PNG. PicBrewery näitab kõiki formaate kõrvuti. Vaadake PNG → WebP või tihenda AVIF.
Korduma kippuvad küsimused
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.
Millal hoida SVG, mitte WebP?
No; metadata is stripped during optimization.
Can I batch-compress PNGs?
Yes — up to 20 files per batch with ZIP download.
