JPG PNG to WebP Converter

Convert JPG or PNG images to WebP format for free with this online image converter. Just pick a file or drag it onto the area below, adjust the quality, then click “Download WebP”. The whole conversion runs entirely in your browser — your image is never uploaded to any server, so it is safe for private or sensitive files.

WebP is developed by Google and typically produces files 25–35% smaller than JPG at comparable visual quality. That means faster page loads, lower hosting bandwidth, and a better Core Web Vitals score — which modern SEO rewards. Use this converter to optimize blog images, product photos, or website assets before uploading them.

Why convert to WebP?

• Smaller files, same quality — a WebP at quality 80% looks nearly identical to the same JPG but can shave up to 30% off the file size.
• Faster websites — smaller images load faster on slow connections, helping your Core Web Vitals and user retention.
• Full transparency support — PNG without hard edges; WebP keeps transparency at a fraction of the PNG size.
• Supported everywhere modern — Chrome, Edge, Firefox, Opera, and Safari 17+ all decode WebP natively.

How this WebP converter works

1. Pick or drop a file — choose a JPG or PNG from your device.
2. Adjust quality — the quality slider directly controls compression; the preview updates instantly.
3. Download your WebP — everything happens locally. No upload, no server, no account.

All processing runs inside your browser using the standard Canvas API on Windows, macOS, Android, iOS, and Linux.

Is this WebP converter safe to use?

Yes — your privacy is protected. This converter never uploads your image to any server. The whole conversion happens locally inside your browser, so no server ever sees, stores, or keeps your file. No data is saved, logged, or shared. It is fully private and works offline too.
