The Conversion Options dialog allows you to specify how the file conversion is to be performed. There are a number of options according to conversion file format:

DWG DXF
Select the AutoCAD version that files are to be converted to. If you want a file version prefix to be added to the name of the converted file, check the Add Version Prefix box.

DWF
Select the DWF format and version for conversions to DWF.

PDF
Select whether to convert the current drawing layout or all layouts. Also, choose whether the current view or zoomed to extents view should be converted. If you would like the converted PDFs merged into a single file, check the Merge Converted Files option.

Other PDF options relate to page size, scale, colors and fonts. If you want to embed in the PDF TTF fonts used in the drawing, check the Embed TTF Fonts option. If you want to convert TTF and SHX fonts into vectors, check the As Geometry options.

SVG
Choose whether the current view or zoomed to extents view should be converted, and select the size in pixels for the converted file. Line Weight Scale allows you to set the thickness of lines in the converted file - higher values for Line Weight Scale increase line thickness.

Bitmaps
These options apply to bitmap conversions - BMP, GIF, PNG, JPG and TIF. Choose whether the current view or zoomed to extents view should be converted, and select the size in pixels for the converted file. Also, select pixel format for the converted file. This determines the number of colors in the bitmap file.
