What the Batch PDF Merger & Stamper Does
The Batch PDF Merger & Stamper is the flagship module of the Maharaja PDF Editor — and the feature that was born directly out of our parent company's real-world logistics operation. When Maharaja Trading was processing 3,000+ customs declarations weekly across 40+ countries, their document team was manually combining PDFs one by one, wasting entire workdays on a task that software should handle automatically.
The Batch Merger was built to eliminate that. Today it powers document operations for freight forwarders, customs brokers, 3PL providers, and major importers processing millions of pages monthly.
Intelligent Merge Engine
Our merge engine preserves PDF internal structure: bookmarks, named destinations, form fields, embedded attachments, and metadata. Unlike basic merge tools that flatten everything, Maharaja Batch Merger maintains document fidelity for customs audits.
Enterprise Stamp Library
Upload your own PNG or SVG stamp assets — corporate seals, approval marks, customs codes — and save them to a reusable library. Apply any stamp to a single page, a page range, or every page across all 500 documents in the batch simultaneously.
Visual Drag-and-Drop Reorder
Before committing to the merge, visually reorder your documents using PDF thumbnail previews. Arrange packing lists before invoices, certificates before declarations — exactly the submission order your customs authority or freight portal requires.
Real-Time Processing Status
Monitor your batch merge in real time with per-document progress indicators, estimated completion time, and an error log for any corrupted or password-protected files. Download completed files while the rest of the batch continues processing.

How to Use the Batch PDF Merger & Stamper
Navigate to the Batch Merger module from your Maharaja PDF Editor dashboard. Use the drag-and-drop upload zone to add your documents — drag directly from your Windows Explorer, Mac Finder, Google Drive (via our cloud connector), or SharePoint. You can upload all file types simultaneously: commercial invoices, packing lists, certificates of origin, HS code classification sheets, and bills of lading.
The uploader will display a thumbnail preview and page count for each document as it uploads. Any encrypted or corrupted files will be flagged immediately so you can address them before committing to the batch merge.

What Logistics Professionals Say
"We process over 1,200 customs entries monthly, each requiring 6–10 documents merged, stamped, and filed. Before Maharaja PDF Editor, this was a 3-person job requiring hours of manual PDF combining. Now one clerk handles the entire batch in under 20 minutes. The batch stamp with our agency's seal is flawless — perfectly positioned every time. Best B2B tool purchase we made this year."

"The API integration was what sold our IT team. We built a direct pipeline from our Oracle TMS — the moment an import shipment is released, it automatically triggers a batch merge of all associated documents into a single CBP submission package. It took one developer afternoon to set up. The documentation is clean and the webhook callback works perfectly."

"The page reordering interface is intuitive — even for our less technical staff. The thumbnail previews make it easy to visually confirm document sequence before the merge. We've cut document preparation time by 70% for our ocean freight clients. The 500-PDF batch limit in the Enterprise plan is more than enough for our largest customers."
