Why Compress Images?
Large image files can significantly slow down website loading speed, negatively impacting user experience and SEO rankings. Compressing images reduces their file size without drastically sacrificing quality. This leads to:
- Faster website load times.
- Improved user experience, especially on mobile devices.
- Reduced bandwidth consumption and hosting costs.
- Better SEO performance as page speed is a ranking factor.
- Easier sharing via email or social platforms with size limits.
How Does It Work?
This tool uses client-side JavaScript and the browser’s Canvas API to compress images directly in your browser. Here’s the process:
- Select your desired maximum target size (e.g., 100 KB).
- Upload your image (JPG, PNG, WebP, GIF, BMP) using the button or drag-and-drop.
- Our tool intelligently adjusts the compression quality and dimensions if necessary to meet the target size.
- Preview both the original and compressed images along with their sizes.
- Download the optimized image with a single click.
Since the compression happens entirely in your browser, your images are never uploaded to any server, ensuring your privacy and security.
