Blurry Image After Compression
Blurry output usually means the quality slider is too low or the image was scaled down aggressively. Raise quality to 80–90% for photos, or resize before compressing so the encoder keeps more detail per pixel.
Adjust quality
In Image Compressor, increase the quality percentage and compare the before/after preview. For web heroes, 82% JPEG is often enough; for print, use PNG or higher JPEG quality.
