Why Convert Images to WebP?
WebP is a modern image format that can provide smaller file sizes while maintaining good image quality. Smaller images can reduce the amount of data a website needs to load, which can be helpful for page speed and overall website performance.
If you are managing a WordPress website, blog, online store, portfolio, or other image-heavy website, converting JPG and PNG images to WebP can be a simple part of your image optimization workflow. Also, if you need to resize photographs or signatures for job portals and exam forms, try our Photo & Signature Resizer.
The actual file-size reduction depends on the original image, dimensions, content, and WebP quality settings. Instead of using the same quality for every image, you can adjust the settings based on how the image will be used.
Why use a browser-based converter?
With client-side conversion, image processing happens directly in your browser. Your images don’t need to be uploaded to a remote server for the conversion process. This can be particularly useful when working with private photos, screenshots, certificates, or other personal images.
Fast, Private & Built for Bulk Conversion
Whether you need to convert one image or dozens of images, the converter is designed to keep the process simple.
You can adjust image quality and scale, convert multiple JPG or PNG files together, and download the results individually or as a ZIP archive.
Along with image optimization, if you are looking to compress PDF files securely, use our free PDF & Document Compressor.
Because processing happens in the browser, you can convert images without the extra step of uploading them to an online server.
