Frequently Asked Questions
How to compress a JPG file?
Upload your JPG file, set the quality level (80% is a good default), optionally set a max width, and click Compress.
What quality should I use for JPG compression?
For web use: 75-85%. For email: 60-75%. For archiving: 90-95%. At 80% quality, most people cannot tell the difference from the original.
How much can I reduce JPG file size?
At 80% quality, JPG files typically reduce by 40-60%. Combined with dimension reduction, you can achieve 70-90% smaller files.
Does JPG compression reduce image quality?
Yes, JPG is a lossy format. Lower quality = smaller file but more visible artifacts. However, at 80%+ quality, the difference is imperceptible for most images.
