About the Merge PDF
Merging PDFs is useful for job applications, visa and tax paperwork, invoices and school assignments, where you need to send several documents as one file. Most online PDF mergers upload your files to their servers. This one doesn’t: the merge happens inside your browser, so contracts, ID documents and bank statements stay on your device. There is no watermark and no account needed.
How to use the Merge PDF
- Click "Choose PDFs" or drag several PDF files onto the box.
- Use the up and down arrows to put the files in the right order. Remove any you added by mistake.
- Click "Merge PDFs".
- Download the combined file, named merged.pdf.
What is kept when merging
Every page is copied exactly as it is — text, images, page size and orientation stay the same. Interactive form fields and bookmarks from the original files may not carry over, so fill in and flatten forms before merging if that matters.
Password-protected PDFs
Encrypted PDFs cannot be merged until the protection is removed. Open the file in a PDF reader with the password and save or print a copy without protection, then add that copy here.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser on your own device. Your files are never uploaded, so nobody else can see them, and nothing is kept after you close the page.
How many files can I merge?
As many as your device can handle, up to 100 MB per file and 200 MB in total.
Does the merged PDF have a watermark?
No. The output contains only your pages.
Can I merge images into a PDF?
This tool merges existing PDFs only. Convert images to PDF first, for example with your phone’s print-to-PDF option.
