Merge PDF guide for sellers: join files into one PDF

Sellers collect PDFs all day: label batches, invoices, manifests, GST papers. Printing or sending them one by one takes time and invites mistakes. One combined file is easier to print, store and share. The tool is free and needs no sign-in.

What Merge PDF does

Merge PDF takes the files you add and places their pages one after another in a new PDF. Pages are combined as they are, so text stays selectable and the content is not changed. You need at least two files to merge.

• Add as many PDF files as you need, by choosing them or dropping them on the page.
• Set the order by dragging the file cards, sorting by name from A to Z, or reversing the list.
• Page size: Keep original leaves every page as it is, Fit to A4 places every page on A4.
• Add a blank page between files when you want a clear break between documents.
• The files are combined inside your browser and are never uploaded.

How to use it

The job has three stages: add, order, merge. Here it is step by step.

• Open Merge PDF and choose your files, or drop them on the page.
• Drag the cards into the order you want. For a long list, sort by name or reverse the order.
• Pick the page size: Keep original or Fit to A4.
• Tick the blank page option if you need a separator between files.
• Press Merge PDF and download the combined file.

How it helps sellers

Most sellers download labels in batches through the day, often from more than one marketplace. Each download is a separate PDF. Merging them gives you one file to send to the printer, so you print once and no batch is left behind in the downloads folder.

The same applies to paperwork. A CA, a bank or a marketplace support team can work faster with one organised file than with ten loose attachments. Put the documents in a sensible order, merge them and send a single PDF.

• Daily dispatch: join the morning and afternoon label batches into one print job.
• GST paperwork: combine a month of invoices into one file for your CA.
• Marketplace documents: put your GST certificate, brand papers and ID copies into one PDF when a form takes a single attachment.
• Batch separation: add a blank page between files so you can see where one batch ends in the printed stack.
• Record keeping: store one merged file per day or per month instead of many small ones.

Tips for a clean result

A few habits keep the merged file tidy.

• Start file names with a date or a number. Sorting by name then puts them in the right order for you.
• Use Keep original for 4x6 thermal labels. Fit to A4 suits mixed documents that go to an A4 printer.
• If a file is password protected, remove the password with Unlock PDF first, then merge.
• If the merged file is too heavy to email, run it through Compress PDF.
