Why are PNG files so large to begin with?

PNG uses lossless compression and stores full color depth per pixel. That is great for sharp graphics and text, but photos in PNG format end up much heavier than the same shot as a JPG.

Should I use PNG or JPG for my image?

PNG for logos, screenshots, and anything with transparency or crisp edges. JPG for photographs. If a PNG is a photo with no transparency, converting to JPG will shrink it far more.

Does compressing a PNG reduce its resolution?

No. The pixel dimensions stay the same. If you need a smaller resolution too, use the resize tool first, then compress the output.

Is PNG compression lossless here?

The tool uses a quality-based approach that reduces colors to shrink the file, which is technically lossy but visually very close to the original at higher settings. Check the preview before downloading.

Does the tool work offline?

After the page loads once, yes. All PNG compression happens locally in your browser, so you can disconnect and keep working on sensitive assets.

How it works

Step 01

Drop in your PNG files

Add screenshots, logos, or graphics with transparency. Processing runs in your browser, so PNGs are never uploaded.

Step 02

Tune the quality

Move the slider to find a smaller file that still looks clean. Transparency is preserved at every quality level.

Step 03

Download the compressed PNG

Save the smaller file with its alpha channel intact. Original dimensions are kept unless you resize separately.

FAQ

Frequently asked questions

Yes. The alpha channel is preserved through compression, so transparent backgrounds stay transparent. This works for logos, icons, and any graphic with see-through areas.
