Frequently Asked Questions
Why convert PNG to WebP?
WebP is designed for efficient web delivery and works in current browsers, content management systems, ecommerce stores, and modern applications. It is useful for product images, interface graphics, logos, and other web assets that need transparency.
Does PNG to WebP preserve transparency?
Yes. Fully transparent and semi-transparent pixels in the PNG remain transparent in the converted WebP, including soft edges, shadows, and translucent overlays.
What WebP quality should I choose?
The default setting is a good balance for most images. Choose a higher value when fine detail matters, or a lower value when reducing page weight is more important. The completed file size is shown after conversion.
Will WebP always be smaller than PNG?
Not always. WebP often produces a smaller file, particularly for detailed images, but simple icons and already optimized PNG files can behave differently. Crest Convert shows both file sizes so you can compare them.
Can I resize the WebP while converting?
Yes. Keep the original dimensions, choose 75%, 50%, or 25%, or enter a custom percentage from 10% to 100%. The width and height change together so the image keeps its proportions.
Do current browsers and WordPress support transparent WebP images?
Yes. Current versions of Chrome, Safari, Firefox, and Edge display transparent WebP images. WordPress core supports WebP uploads from version 5.8, although a hosting configuration or plugin can still restrict particular file types.
Does the WebP keep PNG metadata?
No. The converted WebP contains the visible image and transparency but does not copy PNG text, comments, colour-profile metadata, or other embedded metadata into the output file.
Can I batch convert PNG to WebP?
Yes. Add multiple PNG files, apply the same settings, and convert them together. Download each WebP separately or download every completed image in one ZIP.
Are my PNG images uploaded?
No. PNG to WebP conversion runs locally in your browser. Your images are not uploaded to Crest Convert or stored on our servers.
How can I turn the WebP back into a PNG?
Use the WebP to PNG converter when an editor, presentation, publishing workflow, or upload form specifically requires PNG. Existing transparent pixels are preserved when converting it back.
