Reduce file size without losing visible quality.
Image compression is a tradeoff between visual quality and file size. Higher quality means larger files; lower quality means smaller files but more visible artifacts.
For most photographs, quality 80-85 is a good balance. For screenshots with text, use 90+ to preserve crispness.
The compress tool automatically finds the smallest file that maintains acceptable quality. It uses binary search to test different quality levels and picks the best result — no manual settings needed.
WebP and AVIF produce smaller files than JPEG at equivalent quality. Converting from JPEG to WebP can save 25-35% with no visible quality loss.
