Frequently asked questions
How much smaller will my JPG get?
Most photos compress to 30-70% of their original size at quality 75-85. Higher reduction is possible at lower quality or by letting the compressor scale the image down.
Does compressing a JPG twice make it worse?
Yes, JPG is lossy, so every re-save discards a little more detail. Keep a copy of the original if you plan to compress more than once.
Are my images uploaded to a server?
No. All processing happens locally in your browser; your images never leave your device.
