- Click Merge and download the combined file.
Frequently asked questions
- Are my PDFs uploaded to a server?
- No. Merging happens locally in your browser using the PDF structure itself. Your documents never leave your device — important for contracts, IDs and other sensitive files.
- Is there a limit on the number of files?
- No hard limit. You can merge dozens of PDFs at once; the only constraint is your device's memory.
- Does merging reduce quality?
- No. Pages are copied as-is, without re-compression, so text stays sharp and images keep their original quality.
- Can I merge password-protected PDFs?
- Encrypted PDFs need to be unlocked first — the tool can’t copy pages it can’t decrypt. Open the file with its password in a PDF reader, save an unlocked copy, and merge that.
- How do I control the page order?
- The merged PDF follows the file list from top to bottom. Use the arrows next to each file to rearrange before clicking Merge — pages within each file always keep their original order.
About this tool
Combining PDFs is one of the most common document tasks there is: assembling a job application from a CV and certificates, gathering signed contract pages into one file, or turning a folder of scanned receipts into a single document for accounting. A merged PDF is easier to email, easier to archive and guaranteed to keep its pages in the order you set — it also avoids the classic failure mode of multi-file attachments, where a recipient opens three of your five files and misses the rest.
This tool merges files by copying pages directly at the PDF object level — the same structure your PDF reader parses. Nothing is rendered, rasterized or re-compressed, so text stays selectable and sharp, vector graphics stay vectors, and embedded images remain identical to the source files. Page sizes carry over with the pages themselves, so a mixed batch of A4 and letter documents merges without reformatting. The output is simply a new PDF containing the original pages in the order you arranged them.
Order matters, and you control it: files are merged top to bottom as listed, and the arrows let you rearrange them before merging. There is no practical limit on the number of files — dozens of PDFs merge in seconds, because no network transfer is involved at any point.
That local processing is also a privacy guarantee. Contracts, medical records, financial statements and IDs are exactly the documents people most often need to merge, and exactly the ones that should not sit on a stranger’s server. Here they never leave your device: close the tab and nothing remains anywhere.
