Usage guide
Convert images to WebP and balance quality with file size
WebP can reduce the size of photographs and graphics for web delivery. This converter lets you preview compression locally before replacing the original asset.
How to use WebP Converter
- 1.Choose a supported image from your device.
- 2.Adjust quality and dimensions while watching the preview and output size.
- 3.Download the WebP copy and compare it with the original at the size it will actually be displayed.
Examples
- Large product photo → resize to its display width before conversion.
- Blog header → compare quality settings around detailed edges and text.
- PNG graphic → confirm whether transparency remains necessary.
Limitations and notes
- Repeated lossy conversion can introduce artifacts, so keep the original source file.
- Compression savings vary by image content, dimensions, and the format of the original.
Will WebP always be smaller?
Often, but not always. Already optimized images or simple graphics can produce a similar or larger file.
Does the converter upload my image?
Conversion is designed to run locally in the browser, so the source image does not need to be sent to an image-processing server.
