After merging or scanning several batches, similar-looking pages may appear twice. Matching layouts do not prove matching content. Dates, amounts and signatures may differ. We recommend checking the full pages before preparing a delivery copy.
Compare details that can change
Open the source in a PDF viewer and note the positions of suspected duplicates. Read both at a useful zoom level. This is a manual review checklist, not an automatic detection rule.
| Similar appearance | Check more closely |
|---|---|
| Same form template | Name, date and reference number |
| Same table heading | Rows and totals |
| Signature page | Signer, annotations and stamps |
| Confirmed repeat scan | Completeness and legibility of the copy to retain |
If you cannot confirm which page is required, retain both or ask the document's author. A filename suggesting a newer version is not sufficient evidence by itself.
Remove only confirmed unwanted pages
- Retain the original PDF separately.
- Open Delete PDF pages and choose the file.
- Mark the pages you have checked and do not need.
- Review the selected positions before downloading.
- Open the result and verify the remaining pages and count.
The tool does not use AI or image comparison to identify duplicates. Its code creates a new document from retained pages using PDF-LIB's page-copying capability. At least one page must remain; Adobe's page-deletion instructions also require retaining a page.
Inspect the joins
Read the end of the page before each deletion together with the start of the next retained page. Check tables continuing across pages and appendices. The expected page count alone does not establish that the correct pages were removed.
For pages merely in the wrong position, use Organize PDF. See scanned page order and file positions versus printed page numbers before selecting pages.
Keep a reviewable delivery copy
Give the result a distinct name and inspect that exact file before sending. Test important bookmarks and links too; page copying should not be assumed to preserve every original document-level structure. Processing happens in your browser without uploading the PDF.
