PNG to WebP Converter
Convert PNG images to WebP format online with customizable compression quality.
Run tool
This online PNG to WebP converter transforms your PNG image files into modern WebP format. You can upload an image file or provide Base64 image data, then set an optional compression quality value before running the conversion. The tool uses a standard default quality setting of 85, which balances visual clarity and compact file size. If your original PNG graphic utilizes an indexed color palette, the converter automatically processes it as RGBA to maintain color integrity and transparency transitions in the resulting WebP file. After processing finishes, the tool provides the converted graphic in Base64 format, ready to download, copy, or embed into your web projects and stylesheets. If no image data is supplied or if an invalid file format is uploaded, the converter reports an error message so you can check your source file and try the conversion again.
Instructions
- Select and upload your PNG image file or paste Base64 image data into the input field.
- Adjust the quality setting if needed, or keep the default value of 85.
- Click Run to perform the conversion.
- Copy or save the WebP output in Base64 from the results panel.
Examples
- Converting a transparent PNG icon with default quality (85) to produce a Base64 WebP string.
