Combining 30 receipt scans plus 10 vendor invoices into one expense report PDF is a routine accounting task. The wrong tool turns it into a 20-minute slog. The right one does it in under a minute and adds bookmarks so the reviewer can navigate.

Add to Chrome, FreeThe standard workflow
For a typical month-end expense report:
- Collect every invoice PDF in one folder.
- Rename for chronological order if needed (
2025-01-15-vendor-name.pdf). - Open the extension, switch to Merge mode.
- Drag the whole folder contents into the drop zone.
- Pick Group by source in Bookmark handling so each invoice becomes a top-level bookmark.
- Click Merge, name the output
expenses-2025-01.pdf.
Mixing scanned and digital invoices
Some invoices arrive as clean PDFs (Stripe receipts, vendor portals); others are phone-camera scans (taxis, paper receipts). The extension merges them all into one file regardless of source. Quality differs page to page (predictable), but the file structure is uniform.
For the scanned ones, run them through an OCR pass first if you need the merged file to be searchable.
Naming bookmarks for the reviewer
If you set Group by source, each input filename becomes a bookmark name. So 2025-01-15-uber.pdf appears as a bookmark titled "2025-01-15-uber" in the output. Naming source files with date-vendor pattern makes the merged file self-documenting in the bookmark panel.
Filing receipts after the merge
Two common patterns:
- One merged file per month, source files archived. Lighter on storage, easier to search the merged file by date.
- Per-month merge plus annual merge of the monthly merges. Best for year-end CPA hand-off, gives you 12 monthly PDFs and one annual roll-up.
Common gotchas
- Receipts photographed sideways: rotate before merging (the extension supports per-page rotation in Merge mode).
- Invoice PDFs with the same internal form-field names: flatten before merging to avoid field conflicts in the output.
- Wildly varying page sizes (US Letter receipt + A4 invoice): output preserves each source's page size, no normalization needed.

Frequently Asked Questions
Can I merge 50 invoices into one file?
Yes. The extension has no per-task file count cap. 50 invoices typically merge in around 30-60 seconds depending on file sizes.
Will scanned receipts merge cleanly with digital ones?
Yes. The output file mixes them at the page level. Visual quality differs per source (predictable) but the file works as a single document.
Can I add a cover page or summary?
Generate the cover page separately (Word, Pages, Google Docs export to PDF), then drop it as the first file in the merge order. Simple and reliable.
How do I make sure the reviewer can navigate easily?
Use Group by source in Bookmark handling so each invoice becomes a top-level bookmark named after the filename. Date-vendor filenames work especially well here.
Can the extension extract amounts or do OCR on receipts?
Basic OCR is available in the Pro tier. For dedicated receipt parsing (line-item amounts), use a tool like Expensify or a dedicated OCR service. The extension is purpose-built for merge and split.
