Frequently Asked Questions
How do I compress an image online without losing quality?
Upload your image, adjust the quality slider (0.1–0.95), and choose an output format. A quality of 0.80–0.90 gives a great balance between file size and visual quality.
What image formats are supported for compression?
The tool supports PNG, JPEG, and WebP input formats. You can convert between formats while compressing, such as exporting as WebP for smaller file sizes.
Is my image uploaded to a server?
No. All processing happens directly in your browser using JavaScript. Your images never leave your device, ensuring complete privacy.
How much can I reduce my image file size?
Results depend on the original image and your quality setting. Lowering quality to 0.50 can reduce file size by 60–80%, while 0.80 typically cuts it by 30–50%.
