Next: try Split PDF — Split a PDF by ranges or every page.

Several PDFs, one document: this free merge tool joins your files into a single PDF, in the order you set. It is handy for combining chapters, reports, invoices or scanned pages that arrived as separate files.

Everything happens in your browser, so your documents never leave your device. When you need the opposite job, use the Split PDF tool, or shrink the result afterwards with the Compress PDF tool.

How to use

Drop two or more PDFs into the box above, or click to browse.
Use the Up and Down buttons to set the order, and Remove to drop a file.
Tap “Merge PDFs” and wait a moment while the files are joined.
Download the merged PDF — check the page count in the result message.

Why use Toolsvine

Merging online usually means uploading private documents to a stranger's server and waiting in a queue. Toolsvine merges locally, so contracts, medical forms and school work stay on your own device, and there is no file-count limit or watermark on the result.

How PDF merging works

A PDF is a sequence of pages, each with its own content and size. Merging copies the pages from each source file, in order, into a brand-new PDF. Nothing inside the pages is re-typed or re-rendered: text, images and layout are carried over exactly as they were, so the merged file looks identical to the originals.

Page order and page count

The merged file's page count is simply the sum of the inputs — two 3-page files and one 5-page file make an 11-page PDF. That is why the result message reports the count: if it does not match the sum, a file was probably not what you expected. The order you set with the Up and Down buttons is the order the pages appear, so put cover pages and first chapters at the top.

What merging does not do

Merging does not shrink files, remove pages or change the content. A merged file is roughly the size of its parts added together. If the result is too large to email, compress it afterwards. Bookmarks and form fields from the originals are not always carried over, so check interactive forms after merging.

Frequently asked questions

Is merging PDFs free?

Yes. There is no charge, no account and no limit on how many files you merge in one go. The tool runs in your browser, so there is no server queue either.

Will the merged PDF keep my original formatting?

Yes. Pages are copied, not re-created, so text, images, fonts and layout stay exactly as they were in each source file.

Can I merge scanned PDFs?

Yes. Scanned pages are images inside a PDF, and they merge just like text pages. The result is still a scanned-image PDF, so its text is not searchable unless you run OCR on it.

Is there a file size limit?

Files over 100 MB are refused so the browser tab stays responsive. Most documents are far smaller; if yours is huge, compress it first and merge the smaller copies.

Are my files uploaded anywhere?

No. The merging runs entirely in your browser with JavaScript. Your files never leave your device, and the tool keeps working offline once the page has loaded.
