About the JPG to WEBP Converter
The JPG to WEBP Converter turns JPEG (JPG) images into WebP (WEBP) files right inside your web browser. WEBP versions of your JPG photos are typically 25–35% smaller, which makes web pages load faster and improves Core Web Vitals and SEO.
JPG (or JPEG) is the most widely used photo format in the world. It uses lossy compression to keep photographs small, which makes it perfect for cameras, websites and messaging, but it cannot store transparent areas and loses a little quality every time it is re-saved.
WEBP is a modern format created by Google that produces files 25–35% smaller than JPG or PNG at similar quality, and it supports transparency and animation. All modern browsers support it, but some older apps, editors and upload forms still do not accept WEBP files.
Both formats are lossy. Keep the quality slider around 85–92% to avoid visible artifacts while keeping files small. JPG images have no transparency, so the result looks exactly like the original. You can convert dozens of images at once, optionally limit the maximum width to shrink large photos, and download everything as a single ZIP file. Because the conversion runs locally on your device, your pictures are never uploaded to a server.
How to use the JPG to WEBP Converter
- Drop your JPG files into the upload area, click to browse, or paste an image.
- Adjust the quality or maximum width if needed.
- Wait a moment while each image is converted to WEBP on your device.
- Download files individually or click Download all (ZIP).
