Frequently Asked Questions

What is JPG compression?

JPG compression is a lossy compression method that reduces image file size by selectively discarding data. It's particularly effective for photographs and complex images with gradients.

What quality setting should I use for JPG compression?

For web images, 70-80% quality usually offers the best balance between file size and visual quality. Use higher settings (90%+) for printing or archiving.

Will JPG compression reduce image quality?

JPG uses lossy compression, so some quality reduction is inevitable, but at high-quality settings the differences are usually imperceptible to the human eye.

Can I compress JPGs that have already been compressed?

Yes, but be aware that recompressing an already compressed JPG can cause additional quality loss. It's best to compress from the original image when possible.
