Frequently Asked Questions
How does JPEG compression work?
JPEG uses 'lossy' compression, meaning it selectively discards data that the human eye is less likely to notice, leading to a much smaller file size at the cost of some image data.
Will compression affect image quality?
Yes, since JPEG compression is lossy, reducing the file size too much (e.g., setting quality below 70%) may result in visible artifacts or blurring. We recommend testing different quality levels.
Is this JPEG compressor free?
Yes! Our JPEG/JPG compressor is entirely free to use with no hidden costs or limits on processing volume.
Are my images processed on a server?
No. All compression is handled locally in your browser. Your images remain private and secure on your device.
