PNG versus WebP

Both formats can keep transparency, but WebP often stores web graphics more efficiently.

  • Lossless WebP keeps decoded pixels exact.
  • Lossy WebP can reduce size further but may soften tiny text or edges.
03

When to publish WebP

Use it for transparent web assets where PNG size is slowing delivery.

  • Logos, product cutouts and UI graphics on modern websites.
  • Large transparent illustrations or screenshots.
  • Responsive image sets for mobile-first pages.
04

Protect transparent edges

Preview the image over light and dark backgrounds when edge quality matters.

  • Use lossless mode for pixel art, logos or very small text.
  • Use adjustable quality for large illustrations and photographic PNGs.

No image upload required

The PNG is read and converted by your browser on the current device.

  • Transparent artwork never enters a server-side processing queue.
  • Close the tab to release any remaining temporary data.

Frequently asked questions

Will WebP keep PNG transparency?

Yes. Transparent and semi-transparent pixels are preserved.

Should I choose lossless mode?

Choose lossless for exact graphics; use adjustable quality when a smaller file matters more.

Why did my WebP become larger?

Very small or already optimized PNG files can occasionally be more compact. Compare the displayed sizes before replacing the original.
