Common questions

PNG and WebP conversion questions.

Are PNG images uploaded for conversion?+

No. PNG decoding and WebP creation happen entirely inside your browser.

Will transparent backgrounds remain transparent?+

Yes. The converter keeps the source alpha channel and does not add a white or colored background.

Which WebP quality should I use?+

A setting around 80% is a practical starting point. Increase it for detailed graphics and reduce it when file size matters more.

Why might a WebP file be larger than the PNG?+

Very small or already optimized PNG files may not shrink. The result reports the actual byte difference before download.
