Combining PDFs should be quick, clean, and private. PDF Cubby joins your files into a single document in seconds — reassemble a signed contract, bundle scanned receipts for an expense report, or stitch the sections of a long report into one file. No sign-up, no watermark, and nothing kept afterward.
How to merge pdfs
Add your PDFsChoose two or more PDF files to combine. You can keep adding files until the order looks right.
Arrange the orderDrag the files into the exact sequence you want — the first file becomes the opening pages, and so on.
MergeHit Merge and your files are combined into one document in seconds.
DownloadGrab the finished PDF. It's handled and gone the instant your download is ready — nothing is kept.
What you can do
- Reattach a signed signature page back into its contract
- Bundle scanned receipts or invoices into one expense file
- Combine chapters, sections, or exported pages into a single report
- Join a cover letter, résumé, and portfolio into one application PDF
- Assemble bank or tax statements into one archive
What happens to your file
Your files are never stored. Nothing is parked, queued, or kept — the moment your download is ready, it's gone, and no one ever sees it.
Plenty of online tools store your file on their servers and delete it later. PDF Cubby doesn't keep it at all — there's nothing left behind to clean up afterward.

- Only need part of a file? Pull those pages with Extract Pages before merging.
Frequently asked questions
- Are my files kept anywhere after merging?
- No. Your files are never stored. The moment your merged PDF is ready to download, everything is gone — nothing is parked or queued for later cleanup, and no one ever sees your documents.
- How many PDFs can I merge at once?
- As many as you need — dozens without issue. For very large batches, merging in groups of 10–15 keeps things snappy.
- Does merging reduce quality?
- No. Each page is copied in exactly as-is, with no re-compression — text stays sharp and images keep their original resolution.
- Can I reorder the files first?
- Yes. Drag the files into any order before you merge; the final document follows that sequence.
- Will links and bookmarks survive?
- Page content, text, and hyperlinks are preserved. Complex fillable form fields may be flattened depending on the source files — if you need live form fields, merge those last and check the result.
- Do I need an account?
- No. Merging is free with no sign-up and no watermark.
- Is there a file size limit?
- There's no hard limit. Very large combined files may take a little longer, but they still go through fine.
