About the PNG to WebP Converter

Why convert PNG to WebP?

PNG is lossless and supports transparency, which makes it perfect for logos and graphics — but it can produce big files, especially for anything colorful. WebP gives you the best of both worlds: it keeps transparency like PNG, but compresses far more aggressively, often cutting the file size by 60–80% for graphics. For the web, that's a huge speed win.

This converter re-encodes your PNGs as WebP right in the browser. Transparent areas are preserved, you control the quality, and nothing is uploaded — your images never leave your device.

How to Use This Tool

  1. Add your PNG files. Click to upload, drag & drop, or paste — up to 30 at once.
  2. Choose the quality. Higher keeps more detail, lower makes smaller files — 80–90% is a sweet spot for most images.
  3. Resize if needed. Enter a width in pixels to scale every image; leave it blank to keep the original size.
  4. Download. Save files individually, or hit Download all for the whole batch.

PNG vs WebP

  • Size: WebP is typically far smaller than PNG, especially for illustrations and UI graphics.
  • Transparency: Both support a full alpha channel, so nothing is lost in the switch.
  • Compression: PNG is always lossless; WebP here is lossy but with adjustable quality (it also has a lossless mode in general).
  • Support: Every modern browser renders WebP.

Common Use Cases

  • Faster sites: Replace heavy PNG graphics with lightweight WebP.
  • App icons & UI: Keep crisp transparency at a fraction of the size.
  • Bulk optimization: Convert a whole folder of PNGs in one go.

Frequently Asked Questions

Does it keep PNG transparency?

Yes. WebP supports a full alpha channel, so transparent areas of your PNG stay transparent after conversion.

How much smaller will the files be?

For graphics and logos, WebP is often 60 to 80% smaller than PNG. Each card shows the exact saving.

Is it free and private?

Yes. There is no sign-up or watermark, and all conversion happens locally in your browser, so your images are never uploaded.

Is WebP lossy or lossless here?

This tool uses lossy WebP with an adjustable quality slider, which gives the biggest size savings. At high quality the difference is invisible.

Can I convert many PNGs at once?

Yes, drop in up to 30 files and download them individually or all together.
