PDF merging is the process of combining multiple PDF documents into a single file while preserving the original formatting, layout, and content of each document. Our online PDF merger uses the PDF-lib library to copy pages from each source document and combine them sequentially into a new PDF file. This process maintains the quality and integrity of all text, images, and formatting from the original documents.
Your PDFs never leave your device. All merging happens locally in your browser using client-side JavaScript, ensuring your sensitive documents remain private and secure.
Merge as many PDFs as you need without registration, subscriptions, or hidden fees. No watermarks or usage restrictions on the merged documents.
Instant merging without waiting for server processing or file uploads. Results are available immediately after processing with real-time feedback.
Easily add, remove, and reorder files before merging. Full control over the final document structure and page sequence.
