Frequently Asked Questions
Is this image compressor completely free to use?
Yes, our free online image compressor is 100% free with no hidden costs, watermarks, or usage limits. You can compress as many images as you need.
What image formats are supported?
The image compressor currently supports JPEG and PNG files. For PNG, compression may be less effective due to its lossless nature, but you can still reduce file size.
Does this tool upload my images to a server?
No, the entire compression process runs locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
Will my images lose quality after compression?
The image compressor tool uses lossy compression with adjustable quality. At 100% quality, images are nearly lossless, while lower settings reduce file size with minor, often imperceptible quality loss.
Why is my compressed image larger than the original?
For some PNG images, especially those with simple graphics, re-encoding may increase file size. Try lowering the quality slider or choose a JPEG format for better compression.
