Frequently Asked Questions

How does image compression work without losing quality?
Our tool uses smart 'lossy' compression algorithms. It analyzes the image and selectively reduces the color palette and removes metadata that the human eye can't perceive. The result is an image that looks virtually identical but requires a fraction of the storage space.
How can I reduce an image file size to a specific KB?
While we don't have a strict 'target KB' input, you can use the interactive quality slider. Dragging the slider lower will progressively reduce the KB size. You can see the estimated output size in real-time before downloading.
Is this image compressor really free?
Yes, it is 100% free with no hidden fees, no watermarks, and no daily limits. Because you provide the processing power locally through your browser, we don't have to pay expensive server costs.
Will compressing photos strip EXIF data?
Yes, to achieve the maximum possible file size reduction, our compressor automatically removes non-essential EXIF metadata (like camera model and GPS coordinates).
