Conversion complete? Your TIFF files are saved to the destination folder, ready to use.
What changes when you convert STP to TIFF
STP describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the TIFF afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
