Use PDF Press to combine multiple PDF files into one ordered production document. It is built for print shops, publishers, and anyone preparing multi-file PDF jobs, with local browser processing and a live preview before export.
Direct answer
What is merge PDFs?
Combines multiple PDF files into a single document: merge chapters, sections, or separate print jobs.
Drag and drop additional PDF files alongside your primary document and arrange them in the desired order. The merged output preserves each file's page sizes, fonts, images, and vector content. Use this to assemble multi-chapter books, combine front and back covers with interior pages, or consolidate separate job files into one press-ready PDF.

Best use cases
Key settings
Primary Document
The base PDF file: additional files will be appended after this document.
This is the first file in the merged output. Its pages appear at the beginning. All subsequent files are added in the order they appear in the file list below.
Additional Files
Upload or drag extra PDFs to append after the primary document.
Files are merged in list order. Drag to rearrange. Each file retains its original page dimensions: mixed page sizes (e.g., Letter covers with A4 interior) are preserved as-is. Remove files by clicking the delete button next to each entry.
Summary
Shows the total page count and file order of the merged output.
Expert tip
Merge multiple PDFs before imposition so they are treated as one continuous document. File order determines page order in every downstream operation, so double-check the sequence.
Merging files with different page sizes can cause unexpected scaling in layout tools. Resize all inputs to a common size first, or turn on auto-scale in the layout step.
