Times forwarded: The more times, the stronger the blocks and the colour shift. Range: 1 times to 30 times.
Compression quality: JPEG quality. A smaller value makes the blocks more visible. Range: 5 to 90.
Forwarded size: The long side of the picture when forwarded. A smaller size makes it more blurred. Range: 240 pixels to 1600 pixels.
Yellow-green tint: Each time it is forwarded, the colours turn slightly more yellow-green. Range: 0 to 100.
Noise: Grain added before compression. Range: 0 to 100.
Blur: Number of times the picture is blurred after forwarding. Range: 0 to 10.
Saturation: 100% means no change. Range: 50% to 200%.
Contrast: 100% means no change. Range: 50% to 200%.
Sharpen: Sharpens the picture once at the end. Edges look hard and white outlines appear.

The picture is first reduced to the forwarded size; saturation and contrast are adjusted and noise is added.
Each time it is forwarded, the picture is resized again, the colours turn slightly yellow-green, and it is compressed once as a JPEG at the selected quality. On every second round it is reduced to 94%, so the compression blocks do not line up and the loss builds up each time.
After the last round, blur and sharpening are applied as set. The same picture with the same settings always gives the same result.
The result is downloaded as a JPG (quality 92). You can choose the original size or the forwarded size. Pictures with a long side over 4096 pixels are saved at 4096 pixels. Transparent areas are filled with white or black.
