Merge PDF
Drop PDF files here or click to choose
Join two or more PDFs into one file, in the order you add them. Pages are copied, so real text stays selectable. Bookmarks and the document form catalog are not rebuilt.
Read the guide: Merge, split, or reorganize a PDF
How to use
- Drop at least two PDF files, or click and select them together.
- Check the numbered list. The merge follows that order. There is no drag handle to reorder. If the order is wrong, choose the files again in the order you want.
- Click Merge PDFs. The download is named merged.pdf.
What is copied
Each page is copied into a new document. A sentence you could highlight in the original can still be highlighted afterward. That is different from Compress PDF, which turns pages into pictures.
The code copies pages only. It does not rebuild the outline (bookmarks), file attachments, or the document-level form dictionary. A page that already shows filled-in text usually still shows that text, because the appearance is on the page. Do not assume an interactive form will still calculate or submit after the merge.
Password-protected files fail with an error. This tool does not remove passwords. Very large files are held in memory in the tab, so a merge of several long scans can stall the browser. Split or compress scans first if the tab becomes unresponsive.
A worked example
You have a cover letter PDF, a 6-page contract, and a one-page signature sheet. Add them in that order: letter, contract, signature. The list shows 1, 2, 3. Merge. The result is one PDF with the letter first and the signature last, and you can still select the contract text.
If you added the signature first by mistake, the tool will not let you drag it to the bottom. Select the three files again, signature last. Rotating or deleting a page is a different job. Use Organize PDF after the merge, or instead of it.
When not to use this
- You have only one file. There is nothing to join.
- You need to reorder pages inside one PDF. Use Organize PDF.
- You need bookmarks, attachments, or a working form to survive.
- Any file asks for a password.
Questions
Can I change the order after I drop the files?
No. The list is the order of selection. Drop or choose the files again in the order you want them.
Will the text still be searchable?
Yes, if it was real text before. Pages are copied, not redrawn as images. A page that was already a scan stays a scan.
Why did one file fail?
The usual reason is a password, or the file is not a PDF. The status line shows the error. Remove that file and merge the others.
