Frequently Asked Questions
How much smaller is WebP compared to PNG?▼
WebP is typically 25–35% smaller than PNG for photographic images. For images with flat colors and hard edges, PNG may actually be more efficient. The exact savings depend on image content.
Does the quality slider affect all images the same way?▼
Quality 80–90 is the sweet spot for most images — it produces files visually identical to the original PNG at significantly smaller size. Quality 60–70 gives the smallest files with minor detail loss.
Does WebP support transparency?▼
Yes. WebP supports full alpha channel transparency, so any transparent areas in your PNG will be preserved in the WebP output.
Is WebP widely supported?▼
WebP is supported by all modern browsers including Chrome, Firefox, Edge, and Safari 14+. For older browsers, serve WebP with a JPEG or PNG fallback using the HTML picture element.
Does this tool upload my images to a server?▼
No. All conversion happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
