Quality

Higher values result in higher quality and higher file size.

  • 90 - visually lossless

  • 80 - high quality and reasonable file size

  • 70 - medium-high quality and small file size

  • 60 - space-saving, noticeable blurriness

Effort

higher is better quality or lower file size but slower. Its behavior depends on the mode used.

  • 7 - normal speed with modest file size and good quality.

  • 9 - very slow but produces lowest file size or best quality.

Behavior

  • Lossy - higher values result in higher quality. File size may end up larger, especially for non-photographic images.

  • Lossless and Lossy Modular - higher values always result in lower file size.

Lossy Modular

  • Disabled - uses VarDCT mode, preferred for photographic images.

  • Enabled - offers lower file size and increased eligibility for non-photos. It has a drawback of introducing discoloration and artifacts on the edges. Use it sparingly.

AVIF

Quality

Higher is better quality and bigger size.

  • 90 - visually lossless

  • 80 - high quality and file size

  • 70 - good balance between quality and file size

  • 60 - space-saving

Speed

lower is slower, better quality, and smaller file size

  • 6 - regular speed, and good quality

  • 0 - very slow, the best quality, and smallest file size

WebP

Quality

Higher is better quality and bigger size.

  • 90 - high quality and large file size

  • 80 - reasonable quality and file size

  • 60 - looks fine only from far away

Method

Higher means better quality and/or smaller file size.

Typical values: 4 - 6

Behavior

  • Lossless: higher values result in lower file size.

  • Lossy: higher value result in lower file size and typically higher quality (can be subjective).

JPEG

Quality

Higher is better quality and bigger size.

  • 95 - high quality and very large file size

  • 90 - reasonably high quality and large file size

  • 80 - reasonable quality and file size

  • 60 - looks fine only from far away

Chroma Subsampling

Controls color compression. Lower number means less color information and smaller file size.

  • Default - usually picks 4:4:4, but tries to match the input

  • 4:4:4 - full color, the highest quality and file size

  • 4:2:2 - less color (small visual difference), and significant space-saving

  • 4:2:0 - colors may appear washed out

  • 4:0:0 - grayscale
