Merge PDF
Combine two or more PDFs into a single file. Drag the files into the order you want, and everything is joined on your own device, so nothing is uploaded.

Your files stay on your device. Nothing is uploaded.
How to merge PDF
- Choose or drop the PDF files you want to combine.
- Drag the files into the order they should appear. Add more at any time.
- Select “Merge PDFs” and download the combined file.
Private by design
Most online PDF tools upload your document to their servers. This one doesn’t: Merge PDF runs entirely in your browser, so contracts, forms, IDs and photos never leave your device. It’s free and adds no watermark, and you don’t need an account.
Questions
How many PDFs can I merge at once?
As many as your device has memory for. Dozens of ordinary documents is no problem; very large scans (hundreds of megabytes in total) can be slow on phones.
Will the merged PDF keep links, bookmarks and form fields?
Pages are copied exactly, with their text, images, links and annotations. Bookmarks from the original files aren't carried over, and form fields with the same name in different files may end up sharing a value.
Can I merge only some pages of each file?
Use Organize PDF instead: add every file there and you can delete, reorder and rotate individual pages before saving one PDF.
Are my files uploaded?
No. Every tool runs in your web browser, so your files are read, changed and saved on your own device and never sent to LabAnvil or anyone else. Once the page has loaded, the tools even work offline.
Is it free? Do I need an account?
Free, with no watermark, no daily limit and no account.
