About the Compress PNG
PNG files are perfect for logos, icons and screenshots, but they can be surprisingly large. This PNG compressor reduces the number of colours in the image (quantization) — the same technique used by TinyPNG — so files shrink by 50–80% while transparency stays intact. Prefer zero change to the pixels? Choose Lossless and the file is repacked with maximum compression instead.

Frequently Asked Questions
How do I compress a PNG file?
Upload your PNG files, choose how many colours to keep (256 is best quality) and click Compress. Download the smaller PNGs one by one or as a ZIP.
Does PNG compression keep the transparent background?
Yes. The alpha channel is preserved, so transparent logos and icons stay transparent after compression.
What is the difference between lossless and 256 colours?
Lossless keeps every pixel exactly and only repacks the data, giving a modest saving. 256 colours reduces the palette, which usually cuts the size by 60–80% with little visible change.
Why is my PNG so large?
PNG stores every pixel without lossy compression. Photos saved as PNG are especially large — for photos, converting to JPG or WebP is usually the better choice.
Will compressing a PNG make it blurry?
No. Quantization changes colours slightly but never blurs edges, so text and line art stay crisp. Very low colour counts (32–64) can show banding in gradients.
Can I compress PNG screenshots?
Yes — screenshots compress extremely well because they contain few distinct colours. 128 or 256 colours is usually indistinguishable from the original.
Should I convert PNG to WebP instead?
WebP is smaller still and keeps transparency, and all modern browsers support it. Use PNG to WebP if the image is for a website.
Can I compress many PNGs in one go?
Yes. Select multiple files; each is compressed with the same settings and offered individually or as a ZIP.
Can I also reduce the PNG dimensions?
Yes — pick a maximum width (for example 1280 px) and larger images are scaled down before compression for an even smaller file.
Does the Compress PNG tool store my PNG files?
No. Files are processed in memory for your request and discarded immediately; nothing is kept on our servers.
