What is the Image Compressor?

The Image Compressor is a free, browser-based tool that reduces the file size of JPG, PNG, and WebP images without uploading them to any server. It uses HTML5 Canvas to compress your image entirely on your device — your files stay completely private. Adjust the quality level and choose your output format, then download the compressed file instantly.

How to Use the Image Compressor

  1. Upload your image — drag and drop or click to browse for a JPG, PNG, or WebP file.
  2. Adjust quality — use the quality slider to balance file size against image quality (80% is a good starting point for most use cases).
  3. Select output format — choose JPG, PNG, or WebP for the compressed output.
  4. Click Compress — the compressed image appears with a before/after size comparison.
  5. Download — save the compressed image to your device with one click.
