About Merge PDF
Merging PDFs means joining two or more documents into a single file so they can be sent, printed or archived together. Typical jobs are putting a contract and its appendices in one file, combining scanned pages from different sessions, or collecting invoices for a month into one document.
Add the files you want, put them in the order you need, and the tool writes one new PDF with every page in sequence. Your originals are not changed. If the result needs tidying afterwards, you can reorder, rotate or delete pages in the same way.
Tips
- Put the files in the final order before you merge; the pages follow that order exactly.
- Password-protected files must be unlocked first, because they cannot be combined while encrypted.
- Very large files use a lot of memory, so on a phone merge in smaller batches.
Frequently asked questions
How many PDFs can I merge at once?
There is no fixed limit in the tool. The practical limit is the memory of your device, so merge in smaller groups if the browser slows down.
Will merging change the quality of my pages?
No. Pages are copied into the new file rather than re-rendered, so text stays sharp and selectable.
Can I merge PDFs that have a password?
Remove the password first with the Unlock PDF tool, then merge the unlocked copies.
Are my files uploaded?
Our tools process your files in your browser and we never upload them.
Do I need an account?
No. There is nothing to sign up for, and the tools are free to use.
