About This Tool
Prepare photos for websites or apps that support WebP. See the actual change in file size instead of assuming every image will get smaller.
How to Use
- Select or drag in a JPG / JPEG photo.
- Set WebP quality from 10% to 100%. The default is 90%.
- Click “Convert to WebP,” then compare the previews and file sizes.
- Click “Download WebP” and keep the original JPG for other uses.
Supported Formats
- Input: JPG / JPEG (.jpg, .jpeg).
- Output: WebP (.webp, image/webp). Your browser must support WebP encoding.
Conversion Details
- Quality controls WebP detail and file size. A setting of 100% does not guarantee lossless output. Results may vary slightly between browsers.
- Photo orientation and pixel dimensions stay the same. Conversion does not make the original image sharper.
- The result may be smaller or larger than the original. The actual change is shown, so use the preview to help choose your quality setting.
- Converted images generally do not retain the original EXIF, GPS, or other metadata. Keep the original file if you may need its camera information later.
Maximum file size: 100 MiB. Files over 50 MiB trigger a high memory usage notice. Images are limited to 40 million pixels and 16,384 pixels per side. Resize larger images in another image tool first.

FAQ
What is WebP?
WebP is a common format for photos and web images. It supports transparency and offers another way to balance quality and file size alongside JPG and PNG.
How are WebP and JPG different?
They use different compression methods, and WebP also supports transparency. Converting JPG to WebP does not create a transparent background.
Does 100% quality mean lossless?
No. This quality setting does not guarantee lossless output and cannot recover details already lost in the original JPG.
Why does the tool say my browser does not support WebP?
The tool displays a notice if your browser cannot encode WebP. Try again in a browser that supports WebP output.
Are my images uploaded to a server?
No. Selection, preview, conversion, and download all happen in your browser. Your images are never uploaded to a server.
