Compress PNGs with lossless re-encoding or transparent palette quantization.
Choose the files you need to make smaller and compare their original dimensions and byte sizes.
This variant keeps PNG output and can reduce oversized dimensions while retaining transparency. Set a quality level or an exact KB target. The encoder can reduce dimensions when that is required to reach the target.
Review the resulting file size and dimensions, then download one image or a ZIP for a batch.
About this tool
This variant keeps PNG output and can reduce oversized dimensions while retaining transparency.
Compression combines browser image encoding with optional iterative quality and dimension reduction. Exact targets are approached without sending the source to a server.

This variant keeps PNG output and can reduce oversized dimensions while retaining transparency.
It aims to stay at or below the requested KB target. Results vary by image detail and format, so a very small target can also require smaller pixel dimensions.
You can start with PNG and export PNG, ZIP. Actual decoding support can vary slightly by browser.
PNG Compressor runs in your browser. Your image is not uploaded to Image Toolkit.
