Converted Images
WebP is the recommended image format for modern websites, delivering smaller file sizes than both JPG and PNG while supporting transparency and animation. Our universal Image to WebP converter accepts any common image format — PNG, JPG, BMP, GIF, or SVG — and converts it to optimized WebP in your browser.
Why WebP for Your Website
Google's PageSpeed Insights specifically checks whether your site serves images in "next-gen formats" — and WebP is the most widely supported next-gen format. Converting your entire image library to WebP can reduce total image weight by 30-60%, directly improving your Core Web Vitals scores (LCP, CLS) and potentially boosting search rankings.
WebP is supported by 97%+ of browsers worldwide, including Chrome, Firefox, Edge, Safari, Opera, and all major mobile browsers. Unless you need to support extremely old browser versions, WebP is safe to use as your primary image format.
For websites with hundreds of images, the bandwidth savings from WebP conversion are substantial. A photo-heavy e-commerce site serving 50 product images per page might save 2-5MB of transfer per page load — a meaningful improvement for mobile users on limited data plans and for server bandwidth costs.
Bulk Conversion
This tool supports batch conversion of up to 50 images at once. Drag and drop an entire folder of images, select your quality level, and convert them all in one operation. When processing is complete, download all converted files as a single ZIP archive. This makes it practical to convert entire image libraries without processing them one at a time.
For very large batches (hundreds or thousands of images), processing happens sequentially in your browser. Each image is converted independently, so even if one file encounters an issue, the rest of the batch will complete successfully. The progress bar shows exactly where the process stands at all times.
How to Convert Image to WebP
- Upload your images — drag and drop files onto the converter area, or click to browse your device. You can select up to 50 files at once for batch processing.
- Choose output settings — the output format is pre-selected to WEBP for this page. Adjust the quality slider if you want to control the compression level (available for JPG and WebP).
- Click Convert — the progress bar shows conversion status for each file. Processing speed depends on image size and your device.
- Download results — each converted image gets its own download button. For bulk conversions, use "Download All as ZIP" to get everything in one file.
