Two contracts that should be one file. A cover letter and a résumé a recruiter wants together. Chapter PDFs that belong in a single document. Merging PDFs is one of those small tasks that shows up constantly — and one you shouldn't have to upload sensitive documents to a random website to do.
You can combine PDFs entirely in your browser, for free, with nothing uploaded. Here's how.
Merge PDFs in three steps
Use the free Merge PDF tool — it joins your files locally, so nothing leaves your device.
- Open the Merge PDF tool and add the PDFs you want to combine.
- Put them in the right order (the merged file follows the order shown).
- Click merge and download the single combined PDF.
The opposite: splitting a PDF
Need to break one PDF into pieces instead? The Split PDF tool separates a document into individual files or page ranges — handy for pulling one section out of a large report.
Other page edits you might need
- Rotate PDF — fix pages that scanned in sideways.
- Delete Pages — drop blank or unwanted pages before merging.
- Extract Pages — pull specific pages into their own file.
- Add Watermark — stamp 'Draft' or 'Confidential' across the pages.
- Image to PDF — turn photos or scans into a PDF you can then merge.
Tidy each file first — delete blank pages and fix rotations — then merge, so the final document is clean in one pass.
Why do it in your browser?
Merging often involves exactly the documents you'd least like to hand over: contracts, IDs, financial statements, applications. Browser-based merging keeps every file on your device — there's no upload, no server copy, and no account. Close the tab and nothing remains.
