About the formats

What is PDF?

PDF was created by Adobe in 1993 and is now an open ISO standard. A PDF looks the same on every screen and printer, which makes it the standard for documents, forms, receipts and scanned papers.

Questions

Questions and answers

Is it safe to merge my files here?

Yes. ConvertOrino merges your files with code that runs in your own browser. Nothing is uploaded to a server, nobody else can see your files, and they are gone as soon as you close the page.

Can I change the order of the files?

Yes. Use the arrows next to each file to move it up or down before merging.

Can I merge password protected PDFs?

Encrypted PDFs need to be unlocked first. Open them in a PDF reader with the password and save an unprotected copy.

Is the Merge PDF tool free?

Yes, completely free. There is no sign up, no watermark and no limit on the number of files.

Is there a file size limit?

There is no fixed limit, because your own device does the work. Very large files are limited by the memory of your device. Phones handle files of a few hundred megabytes, computers handle much more.

Does it work on iPhone, Android, Mac and Windows?

Yes. It works in any modern browser, including Safari, Chrome, Edge and Firefox, on phones, tablets and computers. Nothing needs to be installed.
