Try the transparency test PNG
Try it and check the result
- Add the PNG and select WebP.
- Convert and compare the downloaded file size with the original.
- Preview on the background where the image will be published and check text at 100%.
What changes in the output
- An alpha channel is retained, but color detail may change because WebP encoding is lossy here.
- Small or simple PNGs can already be efficient. WebP is not guaranteed to be smaller.
- Animated PNG content is not retained as animation; this tool exports a still image.
If the result looks wrong
Keep the PNG if text or edges become visibly worse. The tool does not expose a lossless-WebP mode or a WebP quality slider.

Change pixel width and height for a website, print layout or social media preset. Enlarging an image does not restore missing detail.
Metadata Remover

PNG to WebP FAQ
How do I convert PNG to WebP?
Drop your PNG file into the tool above, then download the WebP. Everything runs in your browser - your image is never uploaded to a server.
Is converting PNG to WebP free?
Yes. No signup or watermark is required. Batch size is limited by your device memory, and images above 40 million pixels are rejected.
Will I lose quality converting PNG to WebP?
WebP is written at quality 90, which usually beats a comparable JPG on both size and detail.
What is the difference between PNG and WebP?
WebP gives much smaller files than PNG at similar quality — ideal for the web. Smaller than JPG or PNG at similar quality, and every browser shows it.
Does converting PNG to WebP need a plugin or an install?
No. WebP is one of the three formats browsers can encode themselves, so nothing extra is downloaded and conversion is near-instant.
Is transparency kept in the WebP?
Yes. If the PNG has an alpha channel it carries through to the WebP.
Is EXIF and GPS data kept in the WebP?
No. Conversion goes through raw pixels, so EXIF, GPS coordinates, IPTC and XMP are all dropped. That is usually what you want before sharing a photo - but if you need to keep the format and only remove metadata, use the Metadata Remover instead.
