Merge invoices into one PDF
Stack GST or office invoices in date order. Compress afterwards if email or the portal has a size cap.
Merge invoices into one PDF
Accountants, GST filings and clients often want a month of invoices as a single attachment instead of a dozen files. Upload each invoice PDF, drag the first-page previews into date order (or vendor order if that is how the folder is kept), and download invoices.pdf.
Merging concatenates pages. It does not extract GSTIN fields or rename invoices inside the file. Keep the source PDFs until the return or payment is acknowledged.
Date order without renaming
Do not rely on filename sort. A card labelled “invoice-3” may still be January. Use the first-page preview to confirm the date, then drag. If one invoice PDF has pages out of sequence, fix it with Arrange PDF before you merge.
- One PDF for a month or a vendor pack
- Drag into date or checklist order
- Default filename invoices.pdf
- Compress for email after the merge
Size and unused pages
Scanned invoices inflate quickly. If the mailbox rejects the pack, open Compress PDF. Drop blank scanner sheets with Split / Delete Pages, then compress again if needed.

Frequently asked questions
Can I merge GST invoices into one PDF?
Yes. Upload each invoice PDF, drag them into date order and download.
Will this file GST for me?
No. It only joins PDFs. File returns on the official GST portal.
The combined invoice file is too large for email.
Use Compress PDF after the merge. Remove unused pages first if scans include blank sheets.
Can I merge an invoice photo?
Convert the photo with Image to PDF, then add it to the invoice stack.
