What is an Image to WebP Converter?
An Image to WebP Converter changes JPG and PNG images into the WebP format. WebP is a modern image format that reduces file size while keeping strong visual quality. It helps websites load faster, use less bandwidth and perform better on mobile devices. The Spexo Image to WebP Converter supports batch conversion, lossy and lossless modes and optional width resizing. The converter also handles transparency, generates a preview card for each image and packages multiple files into a ZIP download. Your files are processed in your browser and never sent to a server.How to convert images to WebP
Upload your images, adjust the settings and download the converted WebP files. The tool works directly in your browser.- Set the WebP quality. Use the quality slider from 10% to 100%. Lower quality creates smaller files. Higher quality keeps more detail. The default 80% is a good starting point for most website images.
- Choose the conversion mode. Select Lossy for smaller files on websites, blogs and product pages. Select Lossless when you need maximum detail for logos, graphics and transparent PNG images.
- Add a resize width if needed. Use the Resize Width field if you want to downscale large images. Leave it blank to keep the original size. When you enter a smaller width, the tool keeps the image ratio and adjusts the height automatically.
- Upload your images. Click the upload area or drag and drop your files. The tool supports multiple JPG and PNG files at once so you can convert a full group of images in one session.
- Check the preview and savings. Each image gets its own preview card showing the file size before and after conversion. The percentage saved and conversion status appear on each card. Unsupported files are skipped with a status message.
- Download your WebP files. Click Download on any converted image to save it individually. If you convert more than one image, click Download All (.zip) to download all WebP files together.

Smaller files help websites load faster and use less bandwidth on mobile and desktop.- Faster page speed. Lighter images reduce load time, especially on image heavy pages.
- Better user experience. Visitors see banners and product images faster without waiting for large files to load.
- Lower bandwidth usage. Smaller files reduce server transfer and CDN costs over time.
