How does image compression work?

Image compression reduces file size by removing redundant data while preserving visual quality. The tool applies format-appropriate compression to achieve 60-80% size reduction while keeping your original format intact.

What quality setting should I use?

For web images, 70-85% offers the best balance of size and quality. Use 85-95% for print or professional work. For maximum compression (email attachments), try 50-70%. At 80% quality, most images show no visible difference while achieving significant size reduction.

Will compression reduce image quality noticeably?

At 70-85% quality, the difference is often imperceptible to the human eye. Below 50%, quality loss becomes visible with artifacts and blurring. Always preview your compressed images before downloading. For important images, start at 80% and adjust as needed.

Is my data safe? Are images uploaded to a server?

Your images are 100% private and never leave your browser. All compression happens locally on your device. No data is uploaded to any server, making this tool completely safe for sensitive or confidential images.

What image formats are supported?

Input formats include JPG, JPEG, PNG, WebP, BMP, and GIF (static). Your images keep their original format after compression - PNG stays PNG, JPEG stays JPEG, and WebP stays WebP. The original aspect ratio and dimensions are preserved.
