Compress PNG — Reduce Size, Keep Transparency
Shrink PNG file sizes by 30-60% while preserving transparency and sharp details. Browser-based compression — nothing is uploaded.
How It Works

Key Features
Transparency Preserved
PNG compression keeps your alpha channel intact. Transparent backgrounds remain transparent.
Smart Optimization
Our engine analyzes each PNG to apply optimal compression — different strategies for photos vs graphics.
Batch Support
Compress multiple PNG files simultaneously. Consistent settings across your entire batch.
Local Processing
All compression runs in your browser. Your PNG files never touch any external server.
Why Choose ConvertMinify
PNG files preserve perfect quality but can be very large — 5-20MB for high-resolution screenshots and graphics. ConvertMinify reduces PNG sizes by 30-60% using smart compression that understands the PNG format's characteristics.
What makes PNG compression unique is the transparency factor. Many compressors break transparency or force conversion to JPG. ConvertMinify preserves your alpha channel perfectly while still achieving significant size reduction.
