FAQ

How do I convert PNG to WebP?

Drop a PNG, JPG or other image in the upload area or click to browse. Adjust the Quality slider (1 to 100 percent, default 80) and click Convert to WebP. The output size and how it compares with the original appear; click Download WebP to save the file with a .webp extension.

What quality should I choose for WebP?

Lower quality means a smaller file. Around 75 to 85 percent usually looks close to the original for photos; use higher values for graphics with sharp text or edges. You can move the slider and convert again to compare output sizes.

Does the WebP converter keep PNG transparency?

Yes. The image is drawn on a transparent canvas and encoded as WebP, which supports an alpha channel, so transparent areas of PNG files are kept.

Why is my WebP file larger than the original?

Heavily compressed JPEGs or small PNG graphics can grow when re-encoded, especially at high quality. The result then says WebP is larger and by how much. Lower the Quality slider and convert again, or keep the original file if WebP does not save space.

Which browsers can convert images to WebP?

Conversion uses your browser's built-in canvas WebP encoder, which Chrome, Edge, Firefox and Opera provide. Some browsers, notably older Safari versions, cannot encode WebP on canvas and return a PNG instead; the tool then says so and saves that file with a .png extension, so use one of the others to get WebP.

Are my images uploaded to a server?

No. The conversion runs on an HTML canvas in your browser, so your images never leave your device. Metadata such as EXIF data is not copied into the WebP file.
