Compress PNG

About this tool

Reduce the file size of your PNG images for faster uploads, smaller email attachments, or quicker-loading websites — processed entirely in your browser with an adjustable quality slider.

Frequently asked questions

How much smaller will my PNG get?

It depends on the image and quality setting — typically 30–70% smaller with minimal visible quality loss at default settings.

Will compression ever make my PNG bigger?

No — if our compressed result would be larger than your original, we automatically return the original file instead and tell you it's already optimized.

Is my PNG file uploaded anywhere?

No, compression happens entirely in your browser.

Can I compress multiple PNG files at once?

Yes — select multiple files and download them together as a ZIP.
