Compress PNG Online — Free

Reduce PNG size by up to 80% while keeping transparency. Perfect for logos, screenshots and web graphics.

Why Compress PNG Files?

PNGs are heavy by design — screenshots and transparent graphics often weigh megabytes. Large images slow down websites, bloat emails and get rejected by upload forms. Compressing them keeps the same look at a fraction of the size.

How to Compress PNG in 3 Steps

  1. Upload your PNG — drag and drop, batch supported;
  2. Choose a mode — Quality, Balanced or Extreme;
  3. Download the optimized PNG with transparency intact.

What About Transparency?

FileMate preserves the alpha channel — logos, icons and overlays keep their transparent backgrounds. No white boxes, no flattened layers.

Frequently Asked Questions

Is PNG compression lossless?

FileMate uses smart lossy compression tuned for PNG: visuals stay nearly identical while size drops dramatically. Already-optimized PNGs are left untouched.

Can I compress many PNGs at once?

Yes, batch upload is supported.

Are my images private?

Yes. Sources are deleted immediately after compression and results auto-expire.
