How to Merge PDF Files in 3 Simple Steps
Merging PDF files has never been easier. Our free online PDF merger allows you to combine multiple PDF documents into a single file without any software installation. Whether you need to merge contracts, invoices, reports, or any other PDF documents, our tool handles it all with ease.
Step 1: Upload Your PDF Files
Click the "Select PDF files" button or drag and drop your PDFs directly into the upload area. You can select multiple files at once from your computer. The tool supports all standard PDF formats and there's no limit on the number of files you can merge (within browser memory constraints).
Step 2: Arrange in Your Preferred Order
Once uploaded, you'll see thumbnails of your PDFs. Simply drag and drop them to rearrange the order. The final merged PDF will combine your files in exactly the sequence you specify. You can also remove any files you don't want to include.
Step 3: Merge and Download
Click the "Merge PDF" button and wait a few seconds while your files are combined. The merged PDF will automatically download to your computer. You can then use, share, or archive it as needed.
