Slides, tables and images: what survives the trip back
A PDF stores placed glyphs and images, not slides, tables or paragraphs. Which extractions work and which are reconstructions depends entirely on that.

Bleed, fonts and the checks a print shop will run
Print shops reject files for a short and predictable list of reasons. Bleed and font embedding account for most of them, and both are fixable before you send.
Editing PDF text, and why the format resists it
PDFs were designed to be final. Text editing works, within limits that explain every frustrating thing about it — reflow, fonts and find-and-replace included.
Deleting pages is easy. Removing page breaks is not a thing.
One of these is a clean, lossless operation. The other asks a fixed-layout format to stop having pages, which it cannot do.
Invisible text, stray comments and the myth of read-only
A PDF carries more than it shows: an OCR layer under the scan, tracked changes you meant to strip, and permissions that politely ask rather than enforce.
Making one document into many, and paper into a link
Two ways to make a static document do more work: personalising it at scale, and giving printed material a route back to the web.
How to compress a PDF without losing quality
What actually makes a PDF large, which parts shrink without visible loss, and how to hit a 10 MB or 5 MB limit on the first try instead of the fourth.
How to merge PDF files — and keep them in the right order
Combining PDFs is easy. Getting the page order right, keeping the bookmarks, and not quietly destroying the form fields is the part that goes wrong.
Are online PDF tools safe? What actually happens to your file
