Good Afternoon!!

I have a problem with the next command line:

Code: Select all

convert -transparent white -density 300 -quality 90 original.pdf output.pdf
This generate a pdf without background but the fonts are not the same that the original document. I have specified the font in the next way:

Code: Select all

convert -transparent white -density 300 -quality 90 -font Arial original.pdf output.pdf
But I have the same result.

Could somebody help me please?

Thanks in advance!!

The font set that was used in your original PDF is probably not on your system. That may be why the font is changed. Also IM is not a good vector processor. It convert vector data into raster images and cannot convert back to vectors. So your output PDF will be a raster images enclosed in a vector shell.

Also -quality probably does nothing for PDF files. The density is what controls the PDF quality/resolution
