How much can I compress a JPG file?
JPG files can typically be reduced by 40-70% depending on the quality setting. Most photos remain visually identical at 70-80% quality.
What quality setting should I use for JPG compression?
For web use, 70-85% quality is usually ideal. For social media, 60-75% works well. For printing, keep quality above 90%.
