Are my PDF files uploaded anywhere?

No. The merge runs inside your browser, and your files are never uploaded and never stored. You can confirm this by disconnecting from the internet after the page loads: the tool keeps working.

Can I choose the order of the merged pages?

Yes. Files are combined in the order they appear in the list, top to bottom, and you can move any file up or down before merging. Pages inside each file keep their original order.

Why was one of my files skipped?

Usually because it is password protected. A protected PDF can't be opened, so it is left out and named while the remaining files still merge; remove the password in the app you use to open it, then add the file again. A file is also skipped when it could not be read as a PDF at all, which usually means it is damaged or mislabeled.

How many PDFs can I merge at once?

There is no fixed count. Each file can be up to 50 MB, and because the work happens in your browser, a very large merge simply takes a little longer instead of hitting a queue or a quota.

Will links and images survive the merge?

Yes. Pages are copied over as they are, so text, images, and links on the pages keep working. Interactive extras such as fillable form fields and bookmarks may not survive, which is worth checking if your PDF relies on them.

What is the merged file called?

It takes the name of the first file in the merge with -merged added, so report.pdf followed by appendix.pdf becomes report-merged.pdf. You can rename it when you save it, like any download.

Does merging change the quality of my pages?

No. Pages are copied into the new file, not re-rendered or recompressed, so text stays sharp and images keep their original quality.

How it works

Three steps to one PDF

1
Add your PDFs
Drag in two or more PDF files, or browse for them. Each file can be up to 50 MB.
2
Put them in order
The list is the merge order, top to bottom. Move a file up or down, or remove it, until it reads the way you want.
3
Merge and download
Select Merge PDFs and save the combined file. Nothing was sent anywhere, so there is nothing to clean up afterwards.

Why this one

Why use this PDF merger

The order is exactly what you see

Files are combined top to bottom, and every page inside each file keeps its place. What you arrange in the list is what you get in the finished PDF.

02
Your files never leave your browser
The merge happens on the page you are looking at. Your PDFs are never uploaded and never stored, and you can confirm it by going offline after the page loads: the tool keeps working.
03
One locked file doesn't ruin the batch
A password-protected file can't be opened, so it is skipped and named while the rest still merge. You are told exactly which file sat out and why.
04
Numbers you can check
After the merge you see each file's page count, the total, and the real size of the finished PDF. Everything shown is measured from the file you download, not estimated.
05
Built for big files
Pages are copied over in small batches, so the page stays responsive even when the files are long scans.

Who it's for

When you'd use it

Someone assembling a report
Joining a cover letter, the main document, and an appendix into one file that reads in the right order.
A job applicant
Combining a resume, certificates, and reference letters into a single PDF, because many application portals only accept one attachment.
An office manager
Merging a month of scanned invoices or signed forms into one document for filing, instead of forwarding a dozen attachments.
