About converting PNG to WebP

This free PNG to WebP converter runs entirely in your browser. Drop one or more PNG files, adjust quality if available, and download WebP copies — your images never leave this device.

PNG is commonly used for logos and icons. WebP is a better fit when you need website images or product photos. Converting locally means no upload queues, no account, and no third party can see your files.

When to use WebP instead of PNG

Switch from PNG to WebP when the destination app, website, or workflow prefers WebP, or when WebP gives you a clearer quality or size trade-off for your use case.

  • WebP: Often 25–35% smaller than JPG at similar quality
  • WebP: Supports transparency
  • WebP: Great for modern websites and Core Web Vitals
  • PNG limitation: Larger files than JPG or WebP for photos
  • PNG limitation: No built-in photo-style lossy compression

How to convert PNG to WebP privately

Upload is never required. Everything uses your browser’s image decoder and canvas encoder.

  • Choose PNG files (or drag them onto the drop zone).
  • Set quality if the WebP format supports lossy encoding.
  • Click Convert — processing happens on your device.
  • Download each result, or download all when converting a batch.

PNG vs WebP: quick comparison

PNG strengths include lossless quality and full transparency support. WebP stands out for often 25–35% smaller than jpg at similar quality and supports transparency.

If you still need PNG later, keep a master copy. Lossy formats like JPG and some WebP exports cannot recover detail that was discarded during encoding.

Tips for better results

A few practical habits help you keep quality high and files small.

  • Start from the highest-quality source you have — never convert from a heavily compressed preview if you can avoid it.
  • For photos, try WebP or JPG around 80–90% quality before going lower.
  • For logos and screenshots, prefer PNG or lossless WebP so text stays sharp.
  • Resize before compressing if you only need a small display size — fewer pixels usually beat aggressive quality cuts.
