Can I merge PDF files online for free?

Yes, our PDF merger is completely free with no file limits. All merging happens in your browser using the pdf-lib library — your files are never uploaded to any server.

Is there a file size limit for merging PDFs?

Each individual PDF file can be up to 50 MB. There is no limit on the number of files you can merge, though very large combined documents may take longer to process.

Can I reorder pages before merging?

Yes, you can drag and drop to reorder the PDF files before merging. You can also remove individual files from the list. The final merged PDF will follow your specified order.
