Merge PDF files into one document
Three routes to one file: a free desktop tool that keeps every page exact, Word for text-heavy PDFs, and an online merger for one-offs.
Word · PDF · Google Docs how-tos
Document jobs, drawn out step by step.
Every guide here does one job people actually get handed (combine these PDFs into 1 file, make this form fillable, send that as a single document) using the tools already on the desk: Word, the free PDF utilities, Google Docs. No paid software required unless a guide says plainly why.
Start with the two jobs everyone gets handed
Create a fillable form in Microsoft Word
Content controls for text, dates, check boxes and drop-downs, then protection on, so people fill the blanks instead of rewriting the form.
How each guide is laid out
Each guide opens with what the job needs, walks the task as numbered steps in the order you would actually do them, and closes with the finished state to check against — the merged file with its pages in order, the form that tabs cleanly from field to field, plus the snags that most often spoil the same job.
