Compress PNG images and keep transparency

PNG is perfect for logos, icons, and graphics with transparent backgrounds, but the files can get heavy. Drop your PNGs below to make them lighter while keeping sharp edges and full transparency, all processed privately in your browser.

Output is set to PNG. Drag in PNGs to optimize them with transparency intact.

How it works

  1. Drag your PNG files into the upload area.
  2. CompressEasy optimizes each PNG while keeping transparency.
  3. Download the lighter PNGs individually or all at once.

When to use PNG compression

PNG is ideal for screenshots, UI assets, illustrations, and any image that needs a transparent background. Compressing PNGs reduces page weight without flattening or changing the look of your graphics.

Transparency stays intact

CompressEasy keeps the alpha channel, so transparent areas remain transparent. Your logos and overlays drop straight into designs and websites without a white box around them.

Need even smaller files?

For photos and complex images, converting PNG to WebP or AVIF often produces far smaller files. Use the format switch in the tool, or try our dedicated PNG to WebP converter.

Frequently asked questions

Does PNG compression keep transparency?

Yes. The transparent (alpha) channel is preserved, so your logos and graphics stay clean with no added background.

How much smaller will my PNG get?

Savings depend on the image. Flat graphics compress a lot; for photo-like PNGs, converting to WebP or AVIF usually saves much more.

Is it free?

Yes, with a generous free daily allowance. Pro unlocks unlimited compressions and full batch processing.
