What order do the merged pages come in?

The same order the files were selected or dropped — all pages from the first file, then all pages from the second, and so on.

Is anything uploaded to a server?

No. Merging happens entirely in your browser using an open-source PDF library — your files never leave your device.

How to merge PDF files

Drop two or more PDF files into the box above in the order you want them combined, click merge, and every page from every file is stitched into a single PDF, ready to download.

For example, a cover letter saved as one PDF and a resume saved as another can be merged here into a single application document before submitting to a job portal that only accepts one attachment.

What stays intact when merging

Merging copies each page exactly as it exists in the source file — text stays selectable, images stay at full quality, and page sizes are preserved individually, so a mix of letter and A4 pages merges without forcing everything to one size.

Keeping a merged document in order

Merging is one of the most common document tasks there is — combining a cover letter with a resume, joining scanned pages of a contract, or assembling a set of invoices into one file for an accountant. This tool appends each PDF's pages in the order you add the files, keeping every page, image and piece of text exactly as it was in the source document — nothing is re-rendered or re-compressed in the process.

If you add files in the wrong order, the simplest fix is removing them and re-adding them in the sequence you want — the final page order always mirrors the order the source files were selected in, top to bottom.

What stays intact during a merge

A true merge, as opposed to converting each page to an image and reassembling it, copies the underlying PDF page objects directly — meaning selectable text stays selectable, embedded fonts stay embedded, and any links or bookmarks inside the original files carry through unchanged. This is a meaningfully different process from something like Image to PDF, which builds pages from scratch out of pictures.

That page-copying happens through a PDF manipulation library running locally in your browser, so even sensitive documents like contracts or financial statements never pass through a server during the merge.
