Merge PDF Files
Combine PDFs into one document, in exactly the order you want.
Drop files here, or click to browse
PDF files — processed on your device, never uploaded
Combine PDFs without uploading them
Drop in two or more PDF files, arrange them with the up/down controls, and press Merge PDFs. You get a single document with every page in order, ready to download.
Most online mergers send your files to a server and process them there. This one doesn't have a server to send them to: Everything happens locally in your browser — your documents are never uploaded to a server, so contracts, invoices and ID scans stay on your device.
When merging beats attaching
One file is easier to review, sign, print and archive than five attachments. Merge scanned chapters into a single report, bundle invoices for a filing, or stitch a cover letter onto a proposal — the page count and file order are always shown before you commit.
Frequently asked questions
- Is there a file size or count limit?
- No hard limit — because processing is local, the practical limit is your device's memory. Dozens of typical PDFs merge in seconds.
- Are my PDFs uploaded anywhere?
- No. Merging runs entirely in your browser using JavaScript. You can disconnect from the internet after the page loads and it still works.
- Will bookmarks and form fields survive?
- Pages, images and text are preserved exactly. Interactive features like bookmarks and form fields may be flattened or dropped, as with most merge tools.
