About This Tool
Compress PNG images online in your browser — no upload, no signup. Since PNG uses lossless compression, switching to WebP or JPEG typically yields the most dramatic size reductions (often 60–80% smaller). Re-encoding as PNG strips metadata and can reduce file size. All processing is private and runs locally in your browser.

Keep as PNG or convert to WebP or JPEG for much smaller file sizes.
