About Merge PDF
This tool joins multiple PDF files into a single document entirely in your browser. Add two or more files, drag them into the order you want, rotate any file whose pages are sideways, and export one clean PDF with a single click.
It is perfect for assembling reports from chapters, combining scanned pages, or bundling application documents. Because everything runs locally, sensitive paperwork never leaves your device, and there is no file-count limit beyond your device's memory.
How to use Merge PDF Files
- Add two or more PDFs
Drop your PDF files. Each shows its page count and a thumbnail so you can confirm the content.
- Arrange the order
Use the up and down arrows to reorder files, the rotate button to fix sideways pages, and remove any file you don't need.
- Merge and download
Set quality, optionally rename the output file, then click Merge. The combined PDF downloads immediately.
Frequently Asked Questions
How many PDFs can I merge at once?
There is no fixed limit. Because merging happens in your browser, the practical ceiling is your device's memory. Combining dozens of typical documents works fine on a modern phone or computer.
Will the merged PDF keep the original quality?
Pages are re-rendered at high resolution and re-encoded at the quality you choose (default 85%). For most documents the result is visually identical to the originals while staying compact.
Can I merge password-protected PDFs?
No. Encrypted PDFs cannot be opened without their password, and this tool does not accept passwords. Unlock the files first, then merge them here.
