+            PDF editor run the same engine.
+
+            - `bentopdf-pdfium` — the engine wasm, packed from the fork's published `src/vendor`
+            - `bentopdf-viewer` — the snippet bundle, packed **without** `dist/pdfium.wasm`
+
+            The viewer loads the shared engine through `EmbedPDF.init({ wasmUrl })`.
+            CI verified a single wasm on disk, typecheck, and the test suite.

 ## Tips
 
 - For diagonal watermarks across the page, set a rotation around 45 degrees and increase the font size.
+- Tiled mode makes a document much harder to reuse after cropping, since removing one mark still leaves dozens behind. Lower the opacity when tiling so the underlying text stays readable.
 - Image watermarks with transparent backgrounds (PNG format) blend more naturally with the document content.
 - If you need different watermark text on different pages, uncheck "Apply to all pages" and navigate page by page.

+title: Duplex Collate
+description: Reorder duplex scan PDFs that contain front pages and back pages in separate blocks into proper front/back page order.
+---
+
+# Duplex Collate
+
+Duplex Collate is designed for ADF scan workflows where one PDF contains two blocks of pages:
+
+- all front sides first
+- all back sides second
+
+Instead of manually splitting and reassembling, this tool interleaves the two blocks into natural reading order: front1, back1, front2, back2, and so on.
+
+## How It Works
+
+1. Upload a single PDF created from duplex stack scanning.
+2. Set the split point where the front block ends.
+3. Choose back block handling:
+   - **Reverse back block** (common when the stack is flipped before scanning backs)
+   - **Keep back block as-is**
+4. Click **Collate PDF** to download the reordered result.
+
+## Options
+
+- **Auto-detect split (half)**: sets the split point to `ceil(totalPages / 2)`.
+- **Odd page warning**: warns when total pages are odd (often a scan mismatch).
+- **Uneven block confirmation**: asks for confirmation when front/back block sizes differ.
+- **Grouped export**: split the collated output into separate PDFs based on original document page count and download as ZIP.
+
+## Output Behavior
+
+- **Default**: one output PDF (single input PDF in, single output PDF out).
+- **Grouped mode**: output is chunked by your pages-per-document value; if multiple chunks are produced, they are downloaded as one ZIP, otherwise a single PDF is downloaded.
+
+If block sizes are uneven, paired pages are collated first, and remaining unpaired pages are appended at the end.
+
+## Common Use Cases
+
+- Restoring order after scanning a pile of double-sided forms in two passes.
+- Rebuilding front/back packets from office scanners that output all fronts then all backs.
+- Post-processing archive scans before splitting into per-document files.
+
+## Tips
+
+- Most duplex batches should have an even total page count.
+- If output looks inverted on backs, switch between **Reverse back block** and **Keep back block as-is**.
+- For 2-page originals (front+back), use grouped export with `2` pages per document.
