After you convert
Most converted files still benefit from compression, a privacy pass, or a resize for the destination. Pick a next step that matches where the image is going.
What this tool does
This tool converts PNG images to WebP format. WebP, developed by Google, provides superior compression compared to PNG while still supporting transparency. It's widely supported in modern browsers.
Trust and privacy are built into the workflow. Nothing leaves your device during processing, and there is no account setup. That makes it suitable for personal photos, client assets, product shots, and everyday creative work.
How to convert to WEBP
- Upload or drag your file into the tool above.
- Choose output settings such as quality, size, or page options.
- Preview the result before you download.
- Download the finished file for web, email, print, or sharing.
Tip: start with balanced quality settings rather than maximum compression so detail stays intact for web and sharing.
Key benefits
- WebP typically produces files 25-35% smaller than PNG
- Transparency is fully supported in WebP format
- Most modern browsers support WebP, but check compatibility for your audience
- Consider providing PNG fallbacks for older browser support
Privacy note: no files leave your device. All convert steps run locally in your browser.

Common use cases
