About converting JPG to WebP
This free JPG to WebP converter runs entirely in your browser. Drop one or more JPG files, adjust quality if available, and download WebP copies — your images never leave this device.
JPG (JPEG) is commonly used for photos and social media posts. 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 JPG
Switch from JPG 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
- JPG limitation: No transparency (alpha channel)
- JPG limitation: Lossy compression — quality drops each time you re-save

- Choose JPG files (or drag them onto the drop zone).
- Set quality if the WebP format supports lossy 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.
