How to Merge PDF Files Into One (Free, No Software)

Quick answer: open the Merge PDF tool, add your files, use the arrows to put them in order, and tap Merge PDFs. The combined file downloads straight away. It runs in your browser, so nothing is uploaded.

Step by step

1. Add your PDFs. Drag several files onto the box, or tap to choose them (up to 50).
2. Set the order. Use the ▲ ▼ arrows. The numbers on the left show the final order.
3. Tap Merge PDFs. You'll see the page count and size of the result.
4. Download. Save the merged PDF.

Common reasons to merge PDFs

• Combining scanned pages into a single document
• Sending one application file instead of five attachments
• Joining a cover letter, CV and certificates into one PDF
• Putting invoices for the month into one file for your accountant
• Making one printable file from several chapters

Make a PDF from photos first

Have photos or scans as JPG or PNG instead of PDFs? Turn them into a PDF with JPG to PDF, then merge that PDF with your other documents. Choose A4 pages for printable results.

After merging: keep the file small

Merged files add up, and many forms and email providers limit attachments to 10-25 MB. If the result is too large:

1. Run it through Compress PDF. Scans often shrink by 50-80%.
2. Or remove pages you don't need with Split PDF: type the pages to keep, like 1-4, 7.

Fix sideways pages before merging

A scan that came out sideways will stay sideways after merging. Fix it first with Rotate PDF, choosing only the pages that need turning.

FAQ

Is there a limit on file size? Because everything happens on your device, the limit is your device's memory. Normal documents merge instantly; very large scans may take a few seconds.

Will the quality change? No. Pages are copied as they are, so text stays sharp and images aren't re-compressed.

Can I merge password-protected PDFs? No. Remove the password first, then merge.
