Image Compressor

Compress PNG, JPG and WebP images to smaller sizes without uploading.

Free Online Image Compressor — Shrink PNG, JPG & WebP

Large images are the number one reason websites feel slow. Every uncompressed screenshot, camera photo or exported design adds megabytes of weight that visitors have to download before they see your page. This image compressor fixes that in seconds: drop in a PNG, JPG or WebP file, choose a quality level, and download a dramatically smaller version — without uploading a single byte to any server.

The compressor re-encodes your image right inside the browser using the canvas engine, so processing is instant and completely private. A live size estimate shows exactly how much space you are saving while you drag the quality slider, taking the guesswork out of finding the balance between visual fidelity and file size. Dimensions are never touched: your image keeps its exact pixel size and aspect ratio.

Need even smaller files? Switch the output format to WebP — Google's modern format routinely produces files 20–40% smaller than JPG at the same visual quality, which is why it has become the default choice for fast-loading websites. You can also keep the original format when compatibility with older software matters most.

How to Use This Tool

  1. Add an image — drag a PNG, JPG or WebP file into the upload area, click to browse, or paste from your clipboard.
  2. Choose the output format — keep the original format, or switch to JPG or WebP for extra savings.
  3. Adjust quality — move the slider and watch the estimated compressed size update live.
  4. Download — save the optimized image, ready for your website, email or chat app.
