Quick answer: open Kloora PDF Merge, add your PDF files, drag them into order and press Merge. You get one PDF with no watermark, and your files stay on your device.
Common reasons to merge PDFs
- Submitting an application with a cover letter, CV and certificates in one file.
- Joining scanned pages that came out as separate PDFs.
- Combining lecture notes or chapters into one study file.
- Sending a single invoice pack to a client.
Steps
- Open PDF Merge.
- Drag in your PDF files or tap to choose them.
- Reorder the list so the pages come out in the right order.
- Press Merge and download the combined PDF.
Tips
- Name your files 01, 02, 03 before you start so they are easy to line up.
- If you only need some pages from a long file, cut them out first with PDF Split and then merge.
- Need to fix a typo or add a signature after merging? Use the PDF Editor.
- Very large merged files can be slow to email. Check the size before sending.
About privacy
Merging happens locally in your browser. Contracts, certificates and ID scans are never sent to a server, which is the safer way to handle sensitive documents.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
There is no set limit. Very large files depend on your device memory.
Can I change the page order?
Yes. Reorder the files before merging. To rearrange pages inside a file, use the PDF Editor.
Will merging reduce quality?
No. Pages are copied as they are, so text and images keep their quality.
