Convert any supported format to WebP, without switching tools

This tool accepts JPG, JPEG and PNG at once — even mixed in the same batch — so you don't need a different converter depending on your source format. WebP is Google's image format built specifically for the web. It delivers superior compression — both lossy and lossless — meaning sharper images at smaller file sizes. This translates to faster websites, better Google PageSpeed scores, and lower bandwidth costs for your users.

WebP images are 25–80% smaller than their JPG or PNG equivalents with no visible quality loss. This makes converting to WebP one of the simplest, highest-impact optimizations you can make for any website. Our converter runs entirely in your browser — nothing is uploaded to any server, ever.

How to convert your images to WebP in 4 steps

  1. Select your images: drag up to 10 JPG, JPEG or PNG files onto the upload area above — you can mix formats in the same batch — or click to choose them from your computer or phone.
  2. Adjust the quality: move the WebP quality slider. 85% is usually the sweet spot between file size and sharpness — lower it if you want smaller files, or raise it if you need maximum fidelity.
  3. Click "Convert to WebP": conversion happens instantly in your own browser via the HTML5 Canvas API, with no file ever uploaded to an external server.
  4. Download the result: grab each WebP image individually, or click "Download all" to get every conversion in a single ZIP file.

WebP supports two compression modes: lossy (similar to JPG, ideal for photographs) and lossless (similar to PNG, ideal for logos, screenshots, and illustrations with sharp edges). Our converter uses the adjustable lossy mode, which in practice offers the best balance for most web images: product photos on online stores, blog header images, article thumbnails, or attachments for email marketing campaigns.
