Cover letter plus resume. Invoice plus receipts. Ten scanned contract pages in random order. Sooner or later every workflow demands one PDF instead of many — and emailing a zip of parts is how attachments go unread. The Merge PDF card stitches your files into a single document in whatever order you choose, entirely inside your browser: nothing uploads, nothing queues, and a fifty-file merge finishes before your coffee cools.
Order matters more than you think
A merged file reads like one document, so sequence it like one: cover letter first, then resume, then certificates — never the reverse. Drag files into reading order before merging, and double-check page sizes: mixing A4 and Letter originals is fine, but a stray landscape scan in a portrait packet will annoy every reader. When only some pages belong, Split PDF first to carve out exactly the ranges you need, then merge the keepers.
After the merge: shrink it and name it
Merged packets balloon fast — five phone scans can top 25 MB, and most inboxes reject anything over 10–20 MB. Run the result through Compress PDF before sending, and give the file a human name (application-jane-doe.pdf, not merged-final-v2.pdf) since the filename is the first thing a recruiter sees. Built a resume in our Resume Builder? Merge it with your cover letter here and send one attachment that opens identically everywhere.
