Frequently Asked Questions
How much can I compress an image?
Compression depends on the original image and quality setting. Typically, you can reduce file size by 50-80% with minimal visible quality loss at 80% quality. Lower quality settings provide more compression but may show artifacts.
What image formats can I compress?
You can upload JPG, PNG, GIF, and WebP images. The output is always JPEG format, which is ideal for photographs and provides the best compression ratio.
Will compression reduce image dimensions?
No, this tool only reduces file size by adjusting quality. The image dimensions (width and height) remain the same. Use the Image Resizer tool if you need to change dimensions.
What quality setting should I use?
80-85% quality is recommended for most use cases. It provides significant file size reduction with minimal visible quality loss. For web use, 70-80% is often sufficient.
Are my images uploaded to a server?
No, all compression happens entirely in your browser. Your images never leave your device, ensuring complete privacy and security.
