PDF Merger

Combining several PDFs into one document is the sort of task that usually sends people to a website they then have to trust with the files. This does it in the page: the pages of each PDF you add are copied, in the order you arrange them, into a single new document, and nothing is transmitted anywhere. Content is transferred rather than re-rendered, so text stays selectable, quality is unchanged and file size stays proportionate. It suits assembling a submission from separately signed sections, joining scanned pages into one file, or putting an appendix behind a report. Three limits are worth checking first: password-protected PDFs must be unlocked before they can be merged, form fields, annotations and bookmarks may not survive the copy intact, and very large documents are bounded by your device's memory because the whole file is held in the page.
