FAQ
Are my PDFs uploaded?
No. Files are read and merged inside this browser and never leave your device.
What is kept in the merged file?
Every page keeps its text, images, vector graphics and links. Document-level extras such as bookmarks and fillable form fields are not carried over.
Can I merge password-protected PDFs?
No. Remove the password in your PDF app first, then add the file again.
Is there a file size or page limit?
There is no hard limit enforced by the tool. Very large files may slow down or run out of memory depending on your device. As a practical guide, files under 100 MB each and a total of a few hundred pages work well.
What file size can the merged PDF be?
The merged PDF is created in your browser's memory. If the total uncompressed size is very large, the tab may run out of memory. For very large merges, split the work into smaller batches.
In what order are the pages merged?
Pages are merged in the order you arrange the files in the list. Use the ↑ ↓ buttons to reorder. Within each file, page order is unchanged.
