Merge PDF files
Applications often ask for one PDF containing every supporting document. Add your files, put them in the right order, and download a single merged PDF.
Your file stays on your device. This tool runs entirely in your browser — nothing is uploaded to our servers, and nothing is stored.

How to merge PDF files
- Add two or more PDF files.
- Drag them into the order you want.
- Merge, then download the combined file.
Supported formats
PDF in, a single PDF out. Files up to 100 MB each.
Important limitations
Worth knowing before you start, so nothing here comes as a surprise at the point you are submitting a form:
- Page content and page size are preserved, but form fields, digital signatures and bookmarks are not carried across.
- Password-protected PDFs cannot be merged. Remove the password first.
- The merged file is roughly the sum of its parts. If the result is too large, run it through the PDF compressor.
How your files are handled
This tool does its work using your browser’s own image and document engine. Your file is read from your device into the page’s memory, processed there, and offered back to you as a download. It is never sent to Fyleit, never written to a server, and never stored anywhere we can reach.
You can verify that for yourself: load this page, disconnect from the internet, and the tool still works. That is also why there is no sign-up and no email field — we have nothing to attach an account to.
Common problems
The pages are in the wrong order.
Files merge in the order shown in the list, not the order you added them. Drag to reorder before merging.
One of my files will not load.
It is either password-protected or damaged. Open it in a PDF reader, save a fresh copy, and try that.
Pages are different sizes in the result.
Each page keeps the size it had in its source file. Merging does not resize pages.
