PNG GUIDE

Why PNG is the dependable format for clean raster graphics

PNG uses lossless compression and supports alpha transparency, making it especially useful for screenshots, interface graphics, logos and images where crisp edges or transparent pixels matter.

What PNG does especially well

01

Lossless raster quality

Saving PNG does not introduce the block and ringing artifacts associated with lossy JPEG compression.

02

Full alpha transparency

PNG can preserve partially transparent pixels for clean overlays and UI assets.

03

Excellent for screenshots

Text, flat colors and sharp interface edges are preserved very reliably.

BEST FIT

When should you use PNG?

  • Screenshots and interface captures.
  • Logos or graphics that need transparent backgrounds.
  • Raster assets where exact edges and repeated editing matter.

FORMAT CHOICE

When another format is better

For photographs, JPG can often produce much smaller files. For logos that must scale indefinitely, SVG may be a better source format.

Use the format that matches the asset

Move from PNG when another delivery format gives you a better balance of size, scalability or document structure.

PNG format questions

Is PNG lossless?

Yes. Standard PNG compression is lossless, although some optimization tools may optionally reduce the color palette to create smaller files.

Does PNG support transparency?

Yes. PNG supports alpha transparency, including partially transparent pixels.

Are PNG files processed locally?

Supported PNG tools on AllOnline.tools process the source file in your browser rather than uploading it to an application server.
