Merge PDF
A few documents, one tidy file. Add your PDFs, arrange the order and bring them together.
How to combine PDFs
Choose at least two PDF files. You can add more files with the same picker. Use the up and down buttons beside each document to set the order. Merge PDFs creates one new document with every page from the first file, followed by every page from the next, and so on.
A useful order makes a better document
For an application, put the cover letter first, then the main form, then supporting documents. For notes, name your files clearly before adding them. The output keeps the page dimensions from each source, so a file may contain mixed portrait, landscape and paper sizes.
What this merger preserves
It copies document pages, including their visible text and images. Document-level bookmarks, attachments, interactive form behavior and digital signatures are not preserved as working features. Use flattened PDFs for completed forms and keep signed originals. Password-protected or damaged files are rejected; this tool does not remove passwords.
File and page limits
You can add up to 20 documents, each up to 25 MB, with 100 MB total. A job is limited to 500 source pages. Processing uses your browser’s memory, and large or complex documents may work better on a computer. Output is available only after a successful merge.
Frequently asked questions
Are my documents uploaded?
No. The PDF is assembled by an open-source library running in your browser. Your files are not sent to a document-processing service.
Can I come back to the result later?
Download the result before closing the tab. File contents and generated PDFs are not saved in local storage or in an account. Reloading clears the current job.
