PNG Compressor
Compress PNG images in your browser while keeping transparency intact.
ℹ️ About PNG Compressor
PNG Compressor shrinks PNG image file sizes while preserving transparency, which is essential for logos, icons and graphics with see-through backgrounds. Unlike JPG, PNG compression works by reducing the number of colors used in the image rather than introducing blur, so sharp edges and flat colors — common in graphics and screenshots — compress especially well. All processing happens locally in your browser, so the original file never leaves your device.
🛠️ How to Use PNG Compressor
Upload your PNG file, then adjust the compression slider and watch the live preview to see how the file size changes. Transparent areas stay transparent throughout. When the balance of size and quality looks right in the preview, click Download to save the compressed PNG.
