Frequently Asked Questions

Is it safe to merge PDFs online?

Yes. Our tool processes your PDFs entirely in your browser using JavaScript. Your files are never uploaded to any server, so your documents remain completely private.

Is there a limit on the number of files I can merge?

There is no strict limit on the number of files. However, merging a very large number of files or very large PDFs may be slower depending on your device's memory.

Can I reorder pages before merging?

Yes. After uploading your files, you can drag and drop them to rearrange the order. The preview panel shows exactly how the merged document will look.

What happens to my files after merging?

Nothing is stored. Since all processing happens in your browser, your files are never sent anywhere. Once you close or refresh the page, all data is cleared from memory.

Can I merge password-protected PDFs?

Password-protected PDFs need to be unlocked before merging. Please remove the password protection first, then upload the unlocked files.
