Image Compression Guide: Balancing Quality & File Size

Image compression reduces the file size of digital graphics to speed up web transfers and save device storage. DP Sizer recommends starting around 90% quality for photographic JPG or WebP exports and adjusting based on the source image.

Lossy vs Lossless Compression

  • Lossy Compression (JPG, WebP): Reduces file size by selectively discarding subtle pixel data imperceptible to the human eye. Higher compression ratios yield smaller files, but setting quality below 75% can cause block noise.
  • Lossless Compression (PNG): Reduces file size without discarding any pixel data. Ideal for vector logos, illustrations, or graphics with text.

When preparing profile pictures in DP Sizer, keep quality sliders set between 88% and 92%. This provides crisp portrait details while maintaining compact file sizes under 200 KB.
