Combining Multiple PDFs Into One File
Manuscript submission portals, thesis binding requirements, and grant applications often want everything as one file — manuscript, figures, tables, supplementary material, cover letter — not five separate attachments. Merging handles this in one step.
Common scenarios
- Manuscript submission — some journals want a single combined PDF (main text + figures + tables) rather than separate files
- Thesis assembly — combining chapters that were written and exported separately into one final document
- Grant applications — merging the proposal, budget, CVs, and letters of support into the single upload most portals require
- Combining a scanned signature page with a typed document
Upload all your PDF files to Scitero's Merge tool — free, no sign up.
Arrange them in the order you want — the final PDF follows this sequence exactly.
Download the combined file and scroll through the whole thing to confirm nothing is out of order or missing.
⚠️ Check page numbering after merging. If your source files each had their own page numbers starting at 1, the merged document will have those original numbers repeating rather than running continuously. If continuous numbering matters (e.g., a thesis), add page numbers after merging, not before.
