Compress PNG Under 25KB — Free Online

Need a PNG file under 25KB — for an email attachment, a form upload limit, or a faster-loading web page? PNG files are compressed losslessly at the pixel level, then re-encoded with a quality setting to shrink further. Upload your image, drag the quality slider, and download once it's small enough.

Frequently Asked Questions

How do I compress a PNG to under 25KB?+
Upload your PNG image to the free compressor, then drag the quality slider down until the displayed file size is under 25KB. Lower quality means a smaller file but more visible compression artifacts.
Why is my PNG still large after compressing?+
Very large or highly detailed images may need a lower quality setting, or resizing the image dimensions first, to reach a small target size like 25KB.
Does this upload my image to a server?+
No. Compression runs entirely in your browser using the Canvas API — your image never leaves your device.
