About PNG to WebP Converter

Converting PNG to WebP typically reduces file size significantly while preserving transparency — WebP supports transparent backgrounds the same way PNG does, so nothing is lost in that regard during conversion.

This is especially useful for website images, where WebP’s smaller file size directly improves page load speed compared to serving the equivalent PNG, without sacrificing the transparency many PNG graphics rely on.

Worth checking WebP support for your specific destination first — while broadly compatible with modern browsers, some older tools or platforms may still expect PNG or JPG specifically.

Frequently Asked Questions

Is PNG to WebP conversion lossless?

Not strictly. This tool saves WebP at about 97 percent quality, which is visually very close for most images but not mathematically identical to the PNG. There is no lossless option or quality slider. Keep your original PNG if you need exact pixels.

Does the WebP keep my PNG's transparency?

Yes. WebP supports transparency, and the converter keeps the transparent areas of your PNG in the output. That makes it a practical way to shrink logos and cut-outs for the web without adding a white background.

Will the WebP file be smaller than my PNG?

Usually, especially for photos and images with gradients, but the saving is not guaranteed for every file. After converting, compare the sizes yourself. For further reduction, run the result through the Image Compressor with a lower quality setting.

Are my PNG files uploaded anywhere?

No. Conversion happens in your browser, so your images stay on your device. You can select multiple PNG files at once, and each gets its own download. No signup is needed.
