About this tool

Updated

How the merge actually works

The tool creates a new empty PDF, then copies every page from each of your files into it in the order of the list, and saves the result as merged.pdf.

You choose only one thing: the order of the files. There are no options for page ranges, compression or bookmarks. Pages are copied as they are, so text stays selectable and vector graphics stay sharp; nothing is rasterised.

Limits you should know before you start

You can add up to 200 PDFs, each up to 200 MB, and only PDF files are accepted.

Because everything happens in your browser tab, very large or very many files depend on your device's memory. If a merge of hundreds of megabytes stalls, split the job into two smaller merges and merge those results. The output is a single file. Bookmarks, outlines and interactive form behaviour from the source files are not reliably preserved, since pages are copied into a new document.

Good jobs for merge, and better tools for others

Merge PDF fits when you already have finished PDFs and just need them back to back.

• Joining a scanned contract, its signed cover page and an invoice into one file to email. • Stitching monthly statements into a single yearly document. • Assembling chapters exported separately from a word processor. If you only need pages 3 to 7 of a longer document, use Split PDF instead. If your source material is images rather than PDFs, JPG to PDF builds a PDF from them, and Combine Files to PDF handles mixed inputs. If the merged pages are in the wrong sequence, Reorder PDF Pages fixes that afterwards.

Honest limitations

The merged file is not compressed, so its size is roughly the sum of the inputs.

Expect the output to be about as large as all inputs added together; Compress PDF only clears metadata and does not shrink images. There is no page-level preview of the combined result before download, so open merged.pdf once to confirm the order.

FAQ

Can I choose only some pages from each PDF?

No. This tool always copies every page of every file. To use only part of a document, first cut it down with Split PDF or Extract PDF Pages, then merge the results.

In what order do the pages end up?

The order of the file list, top to bottom. Pages inside each file keep their original order. Drag the entries in the list to change it before you click Merge.

Are my files uploaded?

No. The merge runs in your browser using a PDF library, and the files are not sent to a server for this job.

Will bookmarks, form fields or links survive the merge?

Do not count on it. The tool copies page content into a fresh document, so document-level features such as bookmarks and outlines are not carried over. Check the result if you rely on them.

What happens with password-protected PDFs?

The tool opens files while ignoring the encryption flag, so some restricted PDFs may merge, but this site has no tool to add or remove passwords. If a file fails to load, it cannot be merged here.
