Many journal submission systems and grant portals require all documents to be uploaded as a single PDF: main manuscript, figures, tables, supplementary materials, and cover letter combined into one file. This tool merges multiple PDF files in any order you specify, entirely in your browser.
Typical merge use cases in research
Combining a manuscript PDF with separate figure files for a journal that requires a single upload. Merging multiple chapters of a thesis for institutional submission. Combining a CV, research statement, and publications list for a fellowship application. Creating a single proof file from multiple separately edited sections.
Page order and bookmarks
Check your merged PDF carefully before submission. Journal submission guidelines often specify exact document order: title page, abstract, main text, references, figure legends, tables, figures. Some submission systems will be rejected if documents are in the wrong order. This tool preserves the original PDF page order within each file and merges them in the order you arrange them.
