      How to merge PDF files

      Combine complete PDF documents in the exact order you need while leaving the original files unchanged. Everything happens in your browser, and no account is required.

      1. Add PDF files

        Choose two or more PDF files, ZIP archives containing PDFs, or a combination of both. You can also drag the files into the preview area.

      2. Add more documents

        Choose Add more files whenever you need to include another PDF or ZIP archive. PDFs found inside ZIP archives are added to the merge list automatically.

      3. Review each PDF

        Select a document in the merge list to display it in the preview. Check its filename and page count before creating the combined file.

      4. Arrange the merge order

        Use Up and Down to place the documents in the required sequence. Remove any document that should not be included.

      5. Confirm the document sequence

        Read the numbered list from top to bottom to confirm the final order. The summary shows how many PDFs and pages will be merged.

      6. Create and download the merged PDF

        Choose Merge PDFs to combine every document locally. When processing finishes, choose Download PDF to save the new file.

      Questions about Ship Toolkit PDF tools

      These answers apply to all browser-based PDF tools on Ship Toolkit.

      Are my PDF files uploaded to a server?

      No. Ship Toolkit processes PDFs locally with JavaScript in your browser. Your files are not uploaded to Ship Toolkit.

      Will a PDF tool change my original file?

      No. The tool creates a new file for you to download. The original PDF on your device is not overwritten.

      Which PDF files may not work?

      Password-protected, encrypted, damaged, or unusually complex PDFs may not open or process correctly. Very large files may exceed your device's available memory.

      Which browsers are supported?

      Use a current version of Chrome, Edge, Firefox, or Safari. JavaScript must be enabled, and older browsers may not support every feature.

      Can I use the PDF tools on a phone or tablet?

      Yes, but detailed editing is easier on a larger screen. Performance and maximum file size depend on the memory available on your device.

      Why does a large PDF take longer to process?

      Processing happens on your device. PDFs with many pages, high-resolution images, or complex content require more memory and processing time.
