PDF to FITS: what carries over and what does not

PDF 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 FITS afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

PDF to FITS Conversion: FAQ

What are PDF files?

PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics. As opposed to other formats with a similar function, PDFs can be easily transferred between different applications and different operating systems, and generally don't have a very large size. Moreover, they can offer decent image quality in a compressed format and can be secured with passwords or watermarks.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades.
