- Press Save PDF. The preview shows the finished pages before you download.
Why fonts are the hard part
Most PDFs carry only the letters they actually use, a practice called subsetting. If a heading says "Invoice", the file may hold just I, n, v, o, i, c and e. Type "Receipt" and there is no R, p or t to draw with. Many online editors quietly swap the whole line to Arial. This one checks every letter first, keeps the original font whenever it can, and lists the lines where it could not.
