Why convert PNG to WebP?

WebP can reduce delivery size for many web images while retaining transparency.

PNG and WebP compared

PNG is lossless. This WebP encoder exposes a quality control and may use lossy compression, trading some detail for size.

Quality and transparency

Keep transparency or deliberately flatten it. Use a higher WebP quality for text, sharp edges and interface graphics.

Practical uses

  • Optimising transparent website assets
  • Creating WebP product imagery
  • Reducing PNG bandwidth

Private browser-based conversion

Files stay on your device. The shared conversion pipeline validates file signatures, applies browser safety limits and checks the produced file signature. Browser codec support can still vary; the main converter guide explains current limits.

Questions

Frequently Asked Questions

Will WebP keep PNG transparency?

Yes, unless you enable Flatten transparency.

Is PNG to WebP lossless?

Not necessarily. The current browser encoder uses the selected quality setting and does not promise lossless WebP.

Can I convert multiple PNG files to WebP?

Yes. Convert up to 30 files in one batch, subject to the per-file and 300 MB total browser safety limits.

Are PNG files uploaded during conversion?

No. Decoding, pixel processing and encoding run locally in your browser.

Can I convert a different format on this PNG to WebP page?

This landing page accepts PNG input only. Use the main Image Converter for other supported source formats.

Does PNG to WebP preserve metadata?

Metadata is generally removed by the pixel conversion pipeline. The interface reports when requested metadata cannot be safely transferred.
