Free Image Compressor for Website Optimization — No Server Upload
Large images are the number one reason websites load slowly. A single 5MB photo can add several seconds to your page load time, especially on mobile. Our free image compressor solves this by reducing JPG, PNG, and WebP file sizes by up to 90% — all inside your browser without uploading to any server.
Unlike other tools that upload your photos to a remote server for processing, our compressor uses the browser-image-compression library to do everything locally. This means your images are 100% private — they never leave your device.
You can also convert between formats while compressing. Converting PNG to WebP alone saves 25-35% on file size at identical visual quality, and WebP is now supported by Chrome, Firefox, Safari, and Edge.
How to Reduce Image File Size for Email Attachment Free
- Drag and drop your images into the upload area or click to browse files.
- Choose a quality preset — Balanced (80%) works best for most uses.
- Set max dimension (e.g., 1200px for email, 1920px for web) and output format.
- Wait for compression to finish — each image shows original vs compressed side by side.
- Click Download on each image or Download All to save everything at once.
