Need to combine a few PDFs into one file? Maybe you have a scanned contract, a signature page, and an appendix that all belong together — or a stack of receipts your accountant wants as a single document. Merging them by hand is a pain, and most "free" online mergers ask you to upload your files to a stranger's server first. Tekivex's Merge PDF tool does the whole job right inside your web browser, so your documents never leave your computer.
This guide walks you through it step by step. It takes about a minute, there's no sign-up, and there's no watermark stamped across your pages at the end.
How to merge PDFs
- Open the Merge PDF tool in your browser. Nothing to install.
- Drag two or more PDF files onto the drop area, or click it to browse and select them from your device.
- Check the order of your files. This is the order they'll appear in the final document.
- Use the up and down controls next to each file to rearrange them until the sequence is exactly what you want — say, cover letter first, then the report, then the appendix.
- Click the Merge button. The tool combines everything on the spot.
- Your combined PDF downloads automatically to your device. Open it to confirm the pages are all there and in the right order.
That's the whole process. You can merge two files or twenty; the steps are the same.
Good to know and limitations
- Order matters, and you control it. The final document follows the top-to-bottom order shown on screen, so reorder before you click Merge.
- No file-size cap from us. We don't impose a limit on how big your PDFs can be. The only real ceiling is your own device's memory, since all the work happens locally. Very large files on an older phone may feel slow.
- Password-protected PDFs need to be unlocked first. If a file is encrypted, open it in a PDF reader, remove the password (or save an unlocked copy), and then merge that version.
- No account, no watermark, no upload. You won't be asked to register, and nothing gets stamped onto your pages.
If you need to do more than merge — reordering pages inside a single document, editing, or annotating — take a look at Pyntra, our fuller-featured editor. And if you later need to pull specific pages back out of your merged file, the Split PDF tool is the companion to this one.
Common merging scenarios and how to handle them
Combining scanned batches. Scanners often save each page — or each side of a double-sided document — as its own PDF. Drop the whole batch in at once, then sort them in the file list before merging. If a scan came out upside down, run it through Rotate PDF first and merge the corrected copy.
Assembling an application or submission pack. Cover letter, CV, certificates, references: portals frequently insist on "one PDF". Merge them in reading order and give the output a clear name before you upload it. If the pack comes out too large for the portal's size limit, pass the merged file through Compress PDF afterwards.
Adding a signed page back into a contract. Print-sign-scan workflows leave you with the original contract plus a one-page scan of the signature page. Extract everything except the unsigned page with Split PDF, then merge the signed scan into its place.
Troubleshooting
- The merge button stays disabled — you need at least two files. A single PDF has nothing to merge with.
- One of the files is rejected — it is probably password-protected. The tool can't read encrypted PDFs, so unlock the file first (you need to know its password) or open it in Pyntra, which handles encrypted documents.
- The page runs out of memory on a phone — merging several very large scans can exceed a phone browser's memory since everything is processed locally. Retry on a desktop browser, or compress the largest inputs first.
Frequently asked questions
Is this PDF merger really free?
Yes. There's no paid tier, no trial that expires, and no account to create. Open the tool, merge your files, download the result. Because everything runs in your browser, there's nothing for us to charge you to host.
Will there be a watermark on my merged PDF?
No. Many free online tools add a watermark or logo unless you pay. Merge PDF does not — the file you download contains only your pages, exactly as they were.
Are my files uploaded to a server?
No. This is the important part. Your PDFs are read and combined entirely within your browser on your own device. They are never sent across the internet to us or anyone else. If you'd like to understand why that matters and how to verify it, read why browser tools keep files private.
Is there a limit on how many PDFs I can combine?
We don't set one. You can merge as many PDFs as you like. The practical limit is your device's available memory, because the merging happens locally rather than on a powerful server.
Your files never leave your browser — merging happens entirely on your own device.
