.GIF photo background removal and pixelation issues

[BSP]

Hello,

I am new to this paint.net program, however I have used it a handful of times without this issue. I am creating a document for the company I work for and need this picture to look good without a background and crisp. First I create the assembly in Inventor then render it at a high lighting and material accuracy then take a snip it using the windows snipping tool and save

as .GIF in order to remove the background. I have tried different level adjustments and just can not seem to get it to look good. 

I am using version paint.net 4.0.21 and have custom pc built for use with Autodesk Inventor 2018. Any help would be much appreciated.

Thank you in advance, BSP

Use the PNG format instead of the GIF format.

Thank you so much toe_head, that works much, much better.

The reason PNGs work better than GIF is that GIFs are limited to a palette of 256 colors and one level of transparency (yes or no). This is why the edges look choppy and the colors dithered. PNGs have a huge palette and a range of transparency levels, hence the smoother edges and more accurate colors.
