Why PNG Minify?
- • Up to 80% smaller PNG files
- • No uploads — everything stays on your device
- • Perfect for web, apps, and UI assets
Tip for best results:
Icons and UI assets already optimized as SVG or WebP may not compress much further. PNG Minify works best on screenshots and photographic PNGs.
How it works
Three simple steps to smaller PNGs.
1. Upload
Drag & drop your PNG files or browse from your device. We only accept PNG — no JPG or WebP.
2. Compress
PNG Minify optimizes your images entirely in the browser, using adjustable quality settings.
3. Download
Download individual files or all at once as a ZIP archive, ready to use on web or apps.
