Frequently Asked Questions

What does the PDF Merger do?

It combines multiple PDF files into a single document using pdf-lib, entirely in your browser. Nothing is uploaded to a server - your files never leave your device. Drag the tiles to set page order before merging.

What file types does it accept?

PDF files only. The merger preserves the existing page content from each file - text, images, and vector graphics are all carried through. It does not re-render or re-compress page content.

Is there a page or file size limit?

No hard limit, but very large PDFs (200+ pages or 100 MB+) may be slow depending on your browser's available memory. For enormous documents a desktop tool like pdftk or Adobe Acrobat will be faster.

Can I reorder pages between files?

You can reorder at the file level by dragging tiles - all pages from file A will appear before all pages from file B. For page-level reordering within a single PDF, use a dedicated PDF page editor.
