Supported files
Ordinary, unencrypted PDFs. Password-protected PDFs, PDFs with interactive forms and digitally signed PDFs are not supported in this version. Pages are copied as they are, without resizing or recompression, but the result is a newly written file: bookmarks, attachments and tagging are not guaranteed to be kept, and it is not an archival (PDF/A) conversion. Your original files are never changed.
Frequently asked questions
Are my PDFs uploaded?
No. Your PDFs are processed in your browser and are not uploaded. Nothing is saved after you close or reload the page.
Which PDFs can I merge?
Ordinary, unencrypted PDFs without interactive form fields or digital signatures. Password-protected, form and signed PDFs are rejected with a clear message instead of being merged incorrectly.
Will the merged PDF keep text and quality?
Pages are copied rather than turned into images, so selectable text, fonts, vector graphics, images, page sizes and rotation stay as they are. Bookmarks, attachments, tagging and other document-level features are not guaranteed to carry over.
What are the limits?
Up to 20 files, 25.0 MB per file, 50.0 MB combined and 500 pages in total. These keep merging reliable on typical devices.
