Builds a PDF from one or several PDFs and images, seeing every page. Everything happens in your browser: files are not uploaded to any server, which is exactly what matters with a contract or a payslip.
1. Drop, paste or choose PDFs and images: their pages appear in order (if you add several at once, by file name). You can keep adding.
2. Click pages to select them (with Shift, a range), or type a range such as 1-3, 5.
3. With the selection: rotate, remove, move or download it alone. You can also drag pages to reorder them.
4. Download PDF saves the document exactly as you see it.
Merge: add several PDFs and download. Extract: select pages and «Download selection». Images → PDF: add photos (each one is a page, in A4 or at its own size). PDF → images: select pages and «Export selection as image».
If you type a text, it is stamped diagonally and semi-transparent on every page when downloading, at a size that fits. It is a visual stamp: it does not encrypt or protect the document. The standard PDF font does not cover every alphabet (Ł, Cyrillic…): if a character is missing, you are told which.
A protected (encrypted) PDF cannot be edited here: you are warned, and if you can open it, «Print → Save as PDF» in your viewer creates an unprotected copy. Fillable forms and digital signatures are lost when recomposing. Since everything is local, very large files depend on your device's memory.
