FAQs
How do I convert PNG to WebP?
Add a PNG, select WebP as the output format, choose quality or lossless mode, and download the converted .webp file.
Does converting PNG to WebP reduce file size?
Often yes, but the result depends on image content and settings. Compare the displayed file sizes before downloading.
Can WebP keep PNG transparency?
Yes. WebP supports an alpha channel, so transparent areas can remain transparent after conversion.
Which WebP compression is better, lossless or lossy?
Lossless preserves exact decoded pixels. Lossy usually creates smaller files. Use the preview to choose the appropriate balance.
Can I convert multiple PNG files at once?
Yes. Add multiple PNG files or a folder, apply one WebP configuration, and download all results in a ZIP.
Are my PNG files uploaded to a server?
No. Conversion runs locally in the browser, so source files stay on your device.
Does ZIP make converted WebP files smaller?
Usually not by much because WebP is already compressed. ZIP is mainly used to download multiple converted files together.
