PNG Compressor

PNG is lossless, so there's no quality slider to turn down. We re-encode it as efficiently as possible, and only if that's not enough do we scale it down slightly to hit your target — always keeping transparency intact.

Free, with no signup and no watermark. Your images never leave your device.

How small does it need to be?

If re-encoding alone can't reach your target, we'll scale the image down in small steps until it fits — and tell you exactly what we changed.

The honest truth about "compressing" PNG

PNG is a lossless format — there's no quality dial to lower. What actually shrinks a PNG is removing redundant encoding overhead (which we do automatically) and, if needed, reducing pixel dimensions. Any tool claiming to hit an arbitrary tiny target while keeping a PNG "lossless and full size" is not being straight with you.

When PNG isn't the right tool

If your PNG is actually a photograph with no transparency, converting it to JPG or WebP will almost always beat resizing a PNG for target-size purposes — we'll flag this automatically after you upload.

Good for

  • Logos, icons, and UI graphics with transparency
  • Screenshots with sharp text and edges
  • Diagrams and line art

If you need transparency in a smaller file

Try the PNG to WebP converter — WebP keeps transparency but compresses far more efficiently than PNG.

Frequently asked questions

Will compressing my PNG blur it?
Re-encoding alone won't blur anything — it's lossless. If we have to scale dimensions down to reach a very small target, the image will be smaller in pixels, not blurrier at its new size.
Will transparency be preserved?
Yes, always. PNG output keeps full transparency throughout.
Why is my PNG still larger than the target?
Some PNGs — especially detailed photos or screenshots — can't shrink much further without visible resizing. We'll show you the best result we found and explain what changed.
