To merge PDF files, upload two or more PDFs to DIT ToolsKit's Merge PDF tool, arrange them in the order you want, and click Merge. The tool combines them into a single PDF in your browser and gives you a download link in seconds — no account or upload to a server required.
What is Merge PDF?
Merge PDF combines multiple separate PDF files into one single document, keeping every page in the order you choose. It's the fastest way to turn scattered PDFs — like scanned receipts, signed contracts, or report chapters — into one file that's easy to send, print, or archive.

- Click the upload area and select two or more PDF files from your device.
- Review the file list — the order shown is the order pages will appear in the merged file.

Frequently asked questions
Is there a limit to how many PDFs I can merge?
No. You can merge as many PDF files as you like in one go, subject only to your device's memory.
Will merging reduce the quality of my PDFs?
No. Merge PDF copies each page exactly as it is — text stays sharp and images keep their original resolution.
Can I reorder pages before merging?
Yes — the files merge in the order they're listed, so arrange your uploads in that order, or use the Organize PDF tool afterward to fine-tune page order.
Do I need to sign up to merge PDFs?
No account is required for occasional use. Signing in only removes the daily free-use limit and saves your task history.
