WebP for transparent web graphics
WebP supports transparent backgrounds and can reduce the size of graphics and photographs. The quality control uses lossy encoding, so compare small text, edges, and fine details in the result. A higher quality setting may be preferable for line art.
Common questions
Will the transparent background remain transparent?
Yes. The WebP export preserves the source alpha channel. Only JPG exports require a solid background.
Is every WebP smaller than PNG?
No. The result depends on the source image and quality setting. The tool shows the actual original and exported sizes rather than assuming a saving.
