Compress PNG images while preserving transparency. Strip metadata, resize, and optimize your PNGs — all without quality loss. 100% browser-based processing.
PNG files are lossless, which is great for quality but terrible for file size. Screenshots, diagrams, and UI mockups saved as PNG can be surprisingly large. This compressor strips unnecessary metadata and re-renders through Canvas to reduce file size without touching pixel quality. For further savings, you can also resize dimensions.
Why Compress PNG Images?
Transparency Preserved
PNG compression keeps your alpha channel intact. Logos, icons, and overlays stay transparent.
Metadata Removal
Re-rendering through Canvas strips EXIF data, color profiles, and other metadata — often reducing file size by 10-30%.
Resize to Compress
The most effective way to reduce PNG file size is resizing. A 2000px image displayed at 500px wastes bandwidth.
Completely Private
All processing happens locally in your browser. Your images are never uploaded anywhere.
