Frequently asked questions
Is merging PDFs on PDFMax really free?
Yes. You can combine as many PDFs as you like for free, with no account, no subscription and no watermark added to the result.
Is it safe and private?
Your files are processed only to produce the merged PDF and are not shared with anyone. We don't require signup, so no personal data is tied to your file, and uploads are removed from the server automatically after processing.
Is there a file size or page limit?
There's no fixed limit for typical documents — you can merge large files and many of them at once. Very large uploads simply take a little longer depending on your internet speed.
Will merging reduce the quality of my pages?
No. Merging only joins the documents together. Text stays selectable and images keep their original resolution — nothing is re-compressed.
Can I merge PDFs on my phone?
Yes. PDFMax runs in your mobile browser, so you can combine PDFs on iPhone, Android or a tablet without installing any app.
Can I change the order of the files before merging?
Yes. Drag the files into any order you want before you merge, so the final PDF reads exactly the way you need.
