Optimize PNG images in a browser-only batch. Every successful result remains PNG, and files are never uploaded.
Every successful output remains PNG.
Files stay in this browser tab and are never uploaded. Up to 50.0 MiB per file and 200 files.
The batch workspace is ready. Compression becomes available when the verified image optimization adapter loads.
The browser decodes, optimizes, and re-encodes each file as PNG. The tool never switches formats automatically.
PNG compression keeps decoded pixels and alpha lossless while applying stronger DEFLATE encoding and optional metadata removal. Already optimized files may remain unchanged.
