You have three PDFs — a cover letter, a resume, and a portfolio — and the application wants one combined PDF. Or you scanned a document in chunks and need them stitched back together. The job is the same: merge PDFs.

Quick answer

Open the Merge PDF tool, drop your files in any order, drag to reorder, click Merge. One PDF out, in seconds, nothing uploaded.

Step-by-step

Go to getconvertify.me/merge-pdf.
Drop your PDFs (up to 20 at a time).
Reorder with the ↑ / ↓ buttons.
Click Merge N PDFs.
Download merged PDF.

What's preserved

Original page sizes — if you mix A4 and Letter, each page keeps its own size.
Text, fonts, vector graphics, images — all carried over without re-encoding.
Bookmarks and form fields per source document.

The merger uses the source pages directly (object graft, not re-render), so quality is identical to the originals.

Why not just print-to-PDF them together?

Print-to-PDF rasterizes pages to a single page size, kills selectable text, blows up file size, and is fussy on Windows. Convertify keeps every page exactly as it was.

Private — runs in your browser

Files never upload. The merge happens in WebAssembly inside your browser tab. No account, no server, no watermark.

Tips

Cover + resume: cover letter first, resume second — that's the order most ATS systems expect.
Scanned chapters: name the files 01.pdf, 02.pdf, etc. so the default drop order is already correct.
Too many to drag: drop them in batches — already-added files stay put.

Split a PDF — the inverse: extract specific pages.
Delete PDF pages — drop the blanks before merging.
Compress PDF — shrink the merged result for email.

Common questions
