A real document package is almost never one file format. A new-hire onboarding pack is an offer letter in Word, a benefits table in Excel, a slide deck for company policy, and a signed PDF contract. A legal filing is a main agreement plus exhibits that arrived as scans, spreadsheets, and Word attachments. Sending five separate files and hoping the recipient opens them in the right order isn't a process — it's a request for someone to reconstruct your document themselves.
Regular "merge PDF" tools only solve half of this: they combine PDFs with other PDFs. The moment one file in the stack is a .docx or .xlsx, you're stuck converting it first, then merging, then hoping the order didn't shift. Advanced Merge does both steps at once — take any mix of PDF, Word, Excel, PowerPoint, images, and plain text, and it hands back one PDF, in the order you chose, with a table of contents and page numbers already in place.
What It Actually Does to Each File Type
It's worth knowing what happens under the hood before you rely on it for something important, since not every format converts with the same fidelity:
| Input | What ends up in the merged PDF |
|---|---|
| Pages copied through exactly as they were — no re-rendering | |
| Word (.doc/.docx) | Paragraph and heading text, plus table rows, laid out as plain text pages |
| Excel (.xls/.xlsx) | Cell contents laid out as a simple table |
| PowerPoint (.ppt/.pptx) | Slide text content, one slide per page |
| Images (JPG/PNG/WebP/BMP) | Inserted as full-page images, unmodified |
| Plain text (.txt) | Laid out as wrapped text pages |
The honest caveat: Word, Excel, and PowerPoint content comes through as its text and structure, not a pixel-perfect visual copy of fonts, colors, and custom layout. A heading still reads as a heading and a table still reads as rows and columns, but a heavily designed slide or a Word doc with custom styling will look plainer once it's a page in the merged PDF. For content where every input is already a PDF, or where you mainly need the content — not the exact visual design — of the other files, this is exactly the tradeoff you want. If a specific Word or PowerPoint file needs to keep its exact formatting, convert it separately with Word to PDF or PDF to PowerPoint first, then feed the resulting PDF into Advanced Merge alongside everything else.
Step by Step
- Open Advanced Merge and drop in up to 20 files — any mix of the formats above.
- Reorder the list with the ▲▼ buttons until the sequence matches how the final document should read.
- Give each file a section title — this becomes its entry in the table of contents.
- Toggle Table of Contents and Page Numbers on (both default on), and optionally add a watermark like "DRAFT" or "CONFIDENTIAL" across every page.
- Set an output filename and click Merge.
The result downloads as a single PDF with real, clickable bookmarks — not just a note saying where each section starts, but actual PDF navigation any reader (Adobe Reader, Preview, Chrome, mobile viewers) can jump through.
Where This Actually Saves Time
New-hire onboarding packs. Offer letter, employment contract, benefits summary, and company policy deck become one file with a table of contents, instead of five attachments the new hire has to open in the right order themselves.
Legal exhibits. A main agreement plus exhibits that arrived as a scanned PDF, a spreadsheet of figures, and a Word addendum become a single numbered filing, with each exhibit as its own bookmarked section.
Client proposals. A cover letter (Word), a pricing table (Excel), and case study slides (PowerPoint) become one document a client can read start to finish, instead of switching between three different apps to review it.
Portfolios and applications. A resume, a cover letter, and image samples of past work combine into a single PDF that's easier for a reviewer to open once rather than download three separate attachments.
Quick FAQ
Does the file order I set actually control the final order? Yes — the order you arrange the list in before merging is exactly the page order in the output PDF, and it's what the table of contents entries are generated from too.
What happens if I don't give a file a section title? It still merges in — Advanced Merge falls back to the original filename (minus the extension) as its table of contents entry.
Is there a file count or size limit? Up to 20 files per merge. There's no separate page-count limit beyond what 20 files reasonably produce.
Can I merge files without a table of contents, if I just want them combined? Yes — turn off the Table of Contents toggle and it merges the files in your chosen order without adding bookmarks, while page numbers can still be added independently.
Will this work on a phone? Yes — it runs in the browser, so uploading, reordering, and merging works the same on mobile as on desktop.
