Combine several PDF files into one, in the order you add them. Runs in your browser; your documents are never uploaded.
The conversion runs entirely in your browser. Your files stay on your device from start to finish, there is no server copy, and nothing is stored once you leave the page. That is true for every tool on FileFlip.
Combining several PDFs into one is the most common thing anyone needs to do with a PDF, and it is usually needed for something official: an application, an invoice bundle, a signed contract with its attachments. Those are exactly the documents you should not be uploading to a stranger's server, which is why this runs entirely in your browser.
Drop in two or more documents. They are merged in the order you add them, so add them in the order you want them to read.
The list shows each file with its size. Remove anything added by mistake using the cross, then add it again in the right place.
One combined PDF comes back, containing every page of every input in sequence.
Pages are copied from the sources into the new document as they are. Text stays selectable, images keep their original resolution, and the quality of the result is identical to the inputs. The merged file is roughly the sum of the originals in size.
If one document is A4 and another is US Letter, each page keeps its own dimensions in the merged file. Nothing is scaled or cropped to match.
Interactive elements such as form fields, digital signatures and internal links may not survive the merge. If a document is a signed original, keep it as it is rather than merging it.
Split a PDF into one file per page, or extract a chosen range of pages into a new PDF. Everything happens locally in your browser.
Rotate every page or a chosen range by 90, 180 or 270 degrees. Processed in your browser, nothing leaves your device.
Turn PNG, JPG or WebP images into a single PDF, one image per page. Runs entirely in your browser.
