Frequently asked questions

Is the PDF merger really free?

Yes. There is no signup, no watermark and no page limit. Merging happens in your browser, so it costs us nothing to run.

Are my documents uploaded to a server?

No. The files are read by your browser and combined on your own device. Nothing is transmitted, stored or logged.

Does merging reduce quality?

No. Pages are copied byte-for-byte into the new document, so text stays selectable and images stay sharp.

Can I change the order of the files?

Yes. Use the up and down arrows next to each file before merging — the final PDF follows that order.

Can I rotate pages?

Yes. The rotate button turns every page of that file 90 degrees, which is handy for scans that came in sideways.

Can it merge password-protected PDFs?

Encrypted files usually fail. Remove the password in your PDF reader first, then merge.

How many PDFs can I combine at once?

There is no hard limit. Very large batches depend on your device's memory rather than any restriction we set.

Does it work on a phone?

Yes. Tap the drop area to pick files from your phone's storage, iCloud Drive or Google Drive.
