Frequently asked questions

How do I merge PDF files online for free?

Click the box and choose two or more PDFs. Use the arrows to put them in the order you want, then click Merge PDFs and download the combined file. It’s free, with no sign-up.

How do I change the order of the files before merging?

Each file appears in a list with up and down arrows. Move a file up or down until the order is right, since the files are joined from top to bottom. Use the ✕ button to remove a file you added by mistake.

Can I add more files after choosing the first ones?

Yes. Click the box again to add more files. They are added to the end of the list, and you can then reorder them.

How many PDFs can I merge at once?

There’s no fixed limit. Very large files or a long list may be slow on older phones and computers, because everything is handled by your device.

Can I merge only certain pages from each PDF?

Not in the merge tool, which joins every page of each file. To use only some pages, first run each file through our Split PDF tool to keep the pages you need, then merge the results.

Why does merging fail on some PDFs?

Password-protected PDFs can’t be merged until the protection is removed. Use our Remove PDF Password tool first, then merge the unlocked copies. A damaged file can also cause an error, so try opening it in another PDF viewer to check.

Will merging reduce the quality of my PDFs?

No. Pages are copied as they are, so text, images and layout stay the same.

Will bookmarks and form fields be kept?

The pages look the same, but features like bookmarks and fillable form fields may not carry over. If you rely on them, check the merged file before sharing it.

Is my PDF uploaded to a server?

No. The merging happens in your browser, so your files stay on your device and are never sent to our server. This keeps private documents like contracts and statements safe.

Does it work on a phone?

Yes. It works in any modern browser on Android, iPhone, tablets and computers.
