When merging PDFs saves you time
Merging is the quickest way to send one tidy document instead of a pile of attachments: a signed contract with its annexes, a job application with your CV and certificates, or a month of invoices for your accountant.
The tool copies every page exactly as it is, so text stays selectable, links keep working and the quality does not change. Pages keep their original size and orientation, which means you can mix A4 and Letter documents in the same file.
Frequently asked questions
How many PDF files can I merge at once?
You can merge up to 20 files of up to 50 MB each for free. The final document has every page from every file, in the order shown in the list before you click Merge PDF.
Will merging reduce the quality of my PDF?
No. Pages are copied as they are, without re-compressing images or converting text. The merged file looks exactly like the originals and is roughly the size of all of them added together.
Can I merge password-protected PDFs?
Not directly. A protected PDF has to be unlocked with its password first. The tool tells you which file is protected so you can remove it from the list and carry on with the rest.
Are my files uploaded to a server?
No. The conversion runs inside your browser on your own device, so your files are never sent to us or stored anywhere. You can even disconnect from the internet after the page loads and the tool keeps working.
