Frequently asked questions

Are my PDFs uploaded anywhere?

No. The merging happens entirely in your browser. Your documents are never sent to a server.

Does merging reduce the quality?

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

Why does a file show an error?

The file is probably password-protected or damaged. Remove the password in your PDF viewer, save a copy, and add it again.

Can I merge a lot of files?

Yes, but the result is built in your device's memory, so very large batches (hundreds of MB) may be slow on older phones or computers.

Does it keep bookmarks and form fields?

The page content is kept. Bookmarks and some interactive form features from the original files may not carry over into the merged file.
