What does compress png online do?

Reduce PNG file size for websites, uploads, and sharing. Keep PNG output or choose another format before processing.

This page is written and reviewed by the MediaReady team for everyday image workflows: smaller uploads, form limits, website images, email attachments, and social sharing. Choose regular compression when you only need a lighter file, target size when a form needs a specific KB limit, resize when dimensions matter, and WebP when you want a modern web-friendly output. Image tools support uploads up to 100 MB with a 100 megapixel safety cap, remove metadata by default, and process files temporarily with automatic deletion after 24 hours. Very small targets can reduce clarity or dimensions, so start with a practical setting and tighten only when the upload limit requires it. The same workflow covers JPG, PNG, WebP, HEIC, AVIF, TIFF, BMP, and GIF inputs, which helps users prepare images from phones, cameras, design exports, screenshots, and scanned documents.

Compress PNG for screenshots, graphics, and transparency

PNG is useful for graphics, screenshots, logos, and images with transparency. It can also become large, especially for detailed screenshots.

If you do not need PNG transparency, converting to WebP or JPG can often reduce the file further.

Transparent graphics

Keep PNG output when transparency is important.

Web assets

Optimize graphics before adding them to pages or documentation.

Frequently asked questions

Will image quality reduce?
PNG workflows can preserve sharp edges and transparency, but heavy compression or conversion may reduce detail or change file behavior.
Why is my PNG still too large?
PNG files can stay large because they preserve sharp detail and transparency. Try WebP output, JPG output for photos, or resize dimensions.
JPG vs PNG vs WebP: which should I choose?
Keep PNG for transparency or graphics. Use JPG for photos. Use WebP when a smaller modern web format is accepted.
Can I resize dimensions too?
Yes. Resizing a large screenshot or graphic can reduce file size before compression.
