How the Image Size Reducer Works
Our Image Size Reducer is designed to be both powerful and easy to use. It helps you shrink your image files to a specific size in kilobytes (KB), which is perfect for web uploads, email attachments, and online forms that have strict size limits.
The Compression Process
When you upload an image and select a target size, our tool uses a smart, in-browser algorithm. It doesn't just blindly compress the image; instead, it iteratively adjusts the JPEG quality level. It performs a binary search to find the highest possible quality setting that still results in a file size at or just below your target. This ensures you get the best-looking image for the smallest possible size.
Why Use This Tool?
- Precision: Unlike tools that only offer "low, medium, high" quality, you can target a precise file size (e.g., 50 KB).
- Privacy: All processing is done directly in your web browser. Your images are never uploaded to our servers.
- Speed: Get instant results without waiting for server uploads and downloads.
