PDF files · 25 MB per file · 50 MB totalSuppose your assignment has a cover sheet, a report and a reference list in three PDF files. Import all three, move the cover sheet first, then the report and references. Merge them and review the downloaded PDF. Each source keeps its page dimensions, so portrait and landscape pages can coexist. Keep the originals if you need their forms, bookmarks or signatures.
Pages keep their original dimensions and text. Interactive forms, bookmarks, attachments and document-level features may not be preserved.
Up to 20 files, 25 MB per file and 50 MB total. PDF jobs support up to 200 pages. On small screens, the total limit is 20 MB and 100 pages. Password-protected PDFs are rejected rather than bypassed. Your original files are never overwritten.
Choose at least two PDFs, arrange the files with the arrows and select Merge PDFs. Download merged.pdf from the result area. All pages from each file are included in that order.

Yes, in a current browser. Select files from your device and use the same controls. Smaller files and shorter page ranges are recommended on phones because PDF rendering uses memory.
No. You download a new copy. Rebuilding pages can change or lose advanced document features and invalidates digital signatures. Inspect the result before replacing or sending an original.
