Convert PNG images to WebP format entirely in your browser — your files never leave your device. Compared to PNG, WebP maintains full alpha transparantie while reducing bestandsgroottes by 50% or more for graphics with transparantie. It's the best choice for optimizing transparant web icons, logos, UI elements, and design assets. Whether you're building a website, app, or just need smaller transparant images, WebP delivers dramatic savings without losing the transparantie you need.

Hoe te gebruiken

  1. Click the upload area or drag a PNG image (including transparent PNGs) onto the page.
  2. Decoding and WebP encoding start automatically after file selection.
  3. Wait for the progress bar to complete. Transparent images encode slightly longer than JPG-type images.
  4. Preview the converted WebP dimensions and file size (including compression ratio), then click download.

Functies

  • 100% client-side processing: PNG decoding and WebP encoding both happen in your browser — files are never uploaded, protecting privacy
  • Preserves alpha channel: WebP supports transparency — PNG alpha channels are fully retained with no loss
  • Dramatic size reduction: Transparent WebP files are typically 40-60% smaller than equivalent PNGs
  • Lossless compression support: Graphics and icons use lossless WebP for pixel-perfect quality
  • Auto-convert on upload: Select a PNG file and conversion starts immediately — simple, one-step operation
  • Original dimensions preserved: Output WebP matches the exact width and height of your source PNG
  • Compression preview: Shows before/after file size comparison so you can see the space savings

Veelgestelde vragen

Will transparant backgrounds be lost when converting PNG to WebP?

No, transparantie is fully preserved. WebP natively supports alpha transparantie channels. Semi-transparant and fully transparant areas in PNG are retained perfectly with identical visual results.

How much smaller will WebP be compared to PNG?

For logos, icons, and UI screenshots with transparantie, lossless WebP is typically 40-60% smaller than PNG. Photo-based PNGs converted to lossy WebP can achieve even greater compressie. The results are dramatic and immediately visible.

My PNG is lossless — will WebP conversion reduce quality?

This tool uses lossless WebP compressie for graphics-type PNGs, preserving pixel-perfect quality with zero loss. For photo-type PNGs, high-quality lossy compressie is used with no perceptible visual difference.

Which browsers support transparant WebP?

Chrome, Edge, Firefox 65+, and Safari 14+ all support transparant WebP, covering over 97% of users. For very old browsers, use the <picture> tag to serve PNG as a fallback alongside WebP.

Are my PNG images uploadened to a server during conversion?

No uploadens whatsoever. All processing happens locally in your browser via Web Workers. Your PNG files never leave your device. Processing design files and commercial assets is completely safe.

Will animated PNGs (APNG) retain animation when converted to WebP?

APNG animation will not be preserved. While WebP supports animation, the current tool extracts only the first frame as a static WebP image. For animation needs, consider using GIF or converting directly to animated GIF format.

Can I convert WebP back to PNG after converting?

Yes, use the [WebP naar PNG](/image/webp-to-png/) tool to convert back, and transparantie will also be preserved. However, it's recommended to keep original PNG files as backups.

Which types of PNG benefit most from WebP conversion?

All PNGs for web and app use benefit from WebP conversion, especially transparant logos, icons, UI elements, and screenshots — these see the highest compressie ratios and biggest performance gains.
