Quick answer
To merge PDF files, add them to KitFuse, use the arrows to put them in order and press Merge PDFs. All pages are copied into one new PDF that you can download straight away. The merged file contains no author or app metadata from the originals.
How to combine PDF files
- Add your PDFs.
Drag two or more PDF files onto the page or press Choose PDFs.
- Put them in order.
Use the arrows next to each file. The page count is shown for each document.
- Merge and download.
Press Merge PDFs, then download the combined file.
Private PDF merging
Most free PDF sites upload your documents to their servers to merge them. That's a lot of trust to place in a stranger when the files are bank statements, contracts or medical records. KitFuse merges PDFs with an open-source PDF library that runs inside your browser and is stored on our own site, so the documents never leave your device.
What's kept and what isn't
All pages are copied exactly, including text, images, links and form fields. Document-level extras such as bookmarks and the original files' author and app information are not carried over, which keeps the merged file clean. To take pages out instead, use Split PDF. To turn photos into PDF pages, use Images to PDF.
Frequently asked questions
How many PDFs can I merge?
As many as your device can handle, up to 200 files. Large documents need more memory, so very big merges work best on a computer.
Can I merge password-protected PDFs?
No. Remove the password in your PDF app first.
Is there a watermark or page limit?
No. There's no watermark, no page limit and no sign-up.
Are my PDFs uploaded?
No. They're merged in your browser and never leave your device.
