Free Online PNG Compressor Tool
PNG uses lossless pixel compression and supports full transparency, making it suitable for logos, screenshots, interface assets, and other flat graphics. This browser tool re-encodes PNG files locally; already optimized files may shrink little, and resizing changes pixel dimensions even though the PNG encoding itself is lossless.
PNG Compressor Features
Smart PNG Compression
The browser decodes and re-encodes PNG pixels while retaining the alpha channel. Results depend on color complexity and prior optimization, so a smaller file is not guaranteed.
Batch PNG Compression
Compress multiple PNG images at once with our batch PNG compressor. Upload up to 20 PNG files and compress them all simultaneously. PNG batch compression saves time for large photo collections.
Size and Dimension Controls
Keep original dimensions for a straight re-encode, or allow resizing when dimensions can change. Browser PNG encoders may ignore quality hints, so use the displayed output size as the result.
Private & Secure PNG Compressor
Selected PNG files are decoded and re-encoded in this browser session rather than sent to an application upload endpoint.

Choose PNG Compression Settings
Keep dimensions when pixel size must remain unchanged. If a smaller file is more important, allow resizing; the target-size setting is approximate and depends on the browser encoder.
