How does PNG compression work?

Our PNG compressor uses advanced lossless compression algorithms to reduce file size while maintaining image quality and transparency. It optimizes the image data without degrading visual quality.

Will compression affect transparency?

No, our compression tool fully preserves PNG transparency. Your logos, graphics, and images with transparent backgrounds will maintain their transparency after compression.

What's the maximum file size allowed?

You can upload PNG files up to 15MB each. For larger files, we recommend using our batch compression feature to process them in smaller groups.

How much can I reduce PNG file size?

Typically, you can reduce PNG file sizes by 30-70% depending on the image content and compression settings. Our tool finds the optimal balance between size reduction and quality.

Is the compression process secure?

Yes, all compression is done locally in your browser. Your images are never uploaded to our servers, ensuring complete privacy and security of your files.
