PDF merger
Combine two or more PDF documents into a single file in the order you choose. Everything runs locally in your browser — nothing is uploaded to a server. Ideal for joining reports, scans, invoices, and application packets.
How to use
- Click Choose PDFs and select two or more PDF files from your device.
- Drag or reorder the list if needed, then click Merge.
- Download the combined PDF when processing finishes.
What the tool does
Loads each PDF in your browser, copies pages in order, and produces one downloadable merged PDF.
What the tool does not do
Does not OCR scans, remove passwords, edit page content, or compress files. Encrypted PDFs must be unlocked first.
Tips
- Merge in the order you want pages to appear — check the file list before merging.
- Very large PDFs may take longer — keep this tab open until the download starts.
- Use the PDF splitter afterward if you need to remove pages from the merged result.
