Frequently asked questions
Is Velprio free?
Yes. The merge tool is free to use, and you don't need an account.
Are my PDF files uploaded?
No. Merging runs in your browser on your own device, so your files are never sent to a server.
Can I combine multiple PDFs?
Yes. Add as many PDF files as you need, then arrange them in any order before merging.
Is it safe to merge confidential documents online?
With Velprio, your documents are never sent anywhere. Many online PDF tools work by uploading your files to their servers, so you have to trust how those files are stored and when they are deleted. Velprio merges everything inside your browser on your own device, so there is no copy on a server to be kept, leaked or accessed by anyone else.
Can I merge PDFs offline?
Yes. Once the merge page has finished loading, you can disconnect from the internet and keep working — adding files, reordering pages and saving the merged PDF all happen on your device. It is also a simple way to confirm that nothing is being uploaded.
