What is an Image Compressor?
An Image Compressor is a tool designed to reduce the file size of digital images without significantly degrading their visual quality. It works by removing unnecessary metadata and optimizing the color data within the image.
Large images are the #1 cause of slow websites. Compressing your images before uploading them can improve your page load speed, boost your SEO rankings, and save bandwidth for your users.
This tool uses advanced browser-based compression algorithms (like canvas-to-blob) to optimize JPEG, PNG, and WEBP files instantly. Since it runs locally, you can compress gigabytes of photos without waiting for uploads.

- Adjust Quality: Use the slider to find the sweet spot between size and clarity (0.8 is usually perfect).
- Preview: Check the 'Compressed' view and the green text showing your savings (e.g., -50%).
- Download: Click the button to save the optimized file to your device.
