Format guidance

Using WebP instead of PNG

WebP can preserve transparent areas while using lossy compression for the visible image data. This can be useful for web graphics, product cutouts, and illustrations where PNG files are heavy.

For pixel-perfect archival graphics, PNG may still be the better master file. Use WebP as a delivery version and review detailed edges at the chosen quality.

Practical conversion tips

Transparency is retained

Unlike JPG output, WebP can keep transparent pixels from the source PNG.

Review sharp graphics

Inspect small text, flat colors, and edges when choosing a lower lossy quality.

Keep the PNG master

Save the source when you may need lossless edits or another export later.

Frequently asked questions

Does PNG to WebP keep transparency?

Yes. Transparent pixels remain transparent when the browser creates the WebP output.

Is WebP output lossless?

This converter uses the browser's quality-controlled WebP encoder, which should be treated as lossy. Keep the PNG when a lossless master matters.

Will WebP be smaller than PNG?

It often is for detailed images, but not in every case. The completed result shows the exact size.

Where is the conversion performed?

It is performed locally in your browser, without sending the PNG to ToolsWeave.
