Why Choose CedarPDF for Merging?

Visual Drag & Drop Control

Don't guess the order. Our tool shows you a thumbnail of every file, so you can drag and drop them into the exact sequence you need before merging, ensuring your final document is perfectly organized.

100% Private & Secure

Merging documents often involves sensitive data from multiple sources. CedarPDF processes everything locally in your browser. Your files never leave your device, ensuring complete confidentiality.

Unlimited File Batch

Unlike other tools that limit you to 5 or 10 files, we let you merge as many PDFs as your device can handle. Perfect for combining large reports, ebooks, or archives without artificial restrictions.

Free & Lossless Quality

We preserve the original quality of every page. Text remains searchable, links stay clickable, and images retain their clarity. All this, completely free with no watermarks.

Frequently Asked Questions

Can I change the order of files before merging?
Yes! This is one of our key features. Once your files are uploaded, you will see thumbnails for each one. Simply drag and drop them to rearrange the order. The merged PDF will follow the exact sequence you arrange.
Can I add more files after uploading the first batch?
Absolutely. Click the "Add Files" card at the end of your file list to upload more PDFs. They will be added to the end, and you can then drag them to any position you like.
Can I merge password-protected PDFs?
Currently, our tool supports merging PDFs that are not encrypted. If your PDF has an "Open Password," you will need to unlock it first using a PDF reader before uploading it here. However, we do support PDFs with "Permission Passwords" (restricted editing) in many cases.
Does merging affect the quality of my PDFs?
No. Merging is a lossless operation. We simply combine the existing pages into a new file without re-compressing images or altering text. The quality of your merged document will be identical to the originals.
Is there a limit on the number of files I can merge?
There are no artificial limits imposed by us. You can merge unlimited files for free. The only limitation is your device's memory and processing power. For best performance, we recommend keeping the total size under 200MB.
Does this work on Mac, Windows, or Mobile?
Yes, CedarPDF is web-based and works on any device with a modern browser, including Windows PCs, Macs, Linux, iPhone, iPads, and Android tablets. No software installation is required.
