scan-1.pdf … scan-8.pdfReport sections
Written separately, delivered as one
intro.pdf + body.pdfDrop in two or more files. Each is checked as it is added.
Move files up and down until the sequence is right.
The combined document is built in your browser.
Fonts, images and graphics states each page depends on come across with it, so text stays text and the merged file looks like the originals.
The output follows the list exactly, and the list is re-orderable before you commit.
Nothing is uploaded. For contracts, medical records and financial statements that is the whole point.
Merge PDF files into a single document without uploading anything. Each source document is parsed properly and its pages are copied along with the fonts, images and resources they depend on, so the merged file renders exactly as the originals did rather than losing embedded fonts. Drag the list into the order you want; the output follows it precisely. Every step happens in your browser, which is the difference between a private merge and sending your contracts to somebody else’s server.
