## How do I merge PDF files for free without a watermark?

Add your PDFs to Mergevanta's Merge PDF tool, drag them into the order you want and press Merge. You get one combined PDF with no watermark, no sign-up and no page limit. Pages are copied exactly as they are, so text stays selectable and image quality doesn't change.

## Why use Mergevanta

- **Original quality preserved:** Pages are copied byte-for-byte, so vectors stay sharp, text stays selectable and nothing gets re-compressed.
- **Private by design:** Files are encrypted end to end before they leave your device, merged in memory and deleted as soon as your PDF is ready. Nothing is stored or queued.
- **Reorder before you merge:** Drag files into the exact order you want and confirm the page count before you commit.
- **No limits that matter:** Merge dozens of files at once. There are no page caps, no daily quotas and no watermarks.

## How to use it

1. Drop your PDF files onto the drop zone, or browse to pick them.
2. Drag the file cards to set the order you want the pages to appear in.
3. Press Merge and watch the progress bar zip through your files.
4. Download the combined PDF — no copy of it is kept on any server.

## Frequently asked questions

### Does Mergevanta add a watermark to merged PDFs?

No. Mergevanta never stamps a watermark, logo or banner on your pages, however many files you merge. The combined PDF is yours to use for personal or commercial work.

### Are my PDFs uploaded to a server?

Files up to about 4 MB are sent to Mergevanta's server encrypted end to end, merged in memory and deleted as soon as the merged PDF is sent back — nothing is stored. Larger files are merged in your browser.

### Is there a file size or page limit?

There is no artificial limit. The practical ceiling is your device's memory, so merging a few hundred pages on a modern phone or laptop is comfortable.

### Can I merge PDFs without Adobe Acrobat?

Yes. Mergevanta combines PDFs in any modern browser, with no Acrobat licence or other software to install, and it's free.

### Will the merged PDF keep bookmarks and links?

Pages, embedded fonts, images and internal links are preserved. Document-level bookmarks from individual files are not stitched together automatically.

### Can I merge PDFs on my phone?

Yes. Mergevanta is fully responsive, so you can combine PDFs on iOS and Android browsers without installing an app.

### What happens if the server can't be reached?

The merge still finishes: Mergevanta falls back to merging the PDFs directly in your browser.
