Merge PDF files
Add two or more PDFs, arrange them by dragging or with the arrows, then merge into one file. Each row shows its page count before you merge.
Drag & drop PDFs here — or click to choose files
PDF — files stay on your device
How to use it
- Add the PDF files you want to combine.
- Reorder rows by dragging, or with the up/down arrows.
- Press Merge, then download the combined PDF.
Limits & formats
Up to 20 files per merge, 50 MB total and 100 pages total. Encrypted PDFs cannot be merged here — the tool reports them instead of guessing. Reordering is by row (drag on desktop, arrows on touch).
Privacy
Your PDFs are processed locally in this browser tab. YYSI servers never receive your files. Only anonymous usage counters (tool name, success or failure, rough size range) are recorded.
