About Signature PDF
Signature PDF is a web tool for signing and organizing PDF files. Users can add signatures, initials, stamps, typed text, strikethroughs and watermarks to a document, and a shared link allows several people to sign the same file. Beyond signing, it can combine PDFs, reorder, extract, rotate or delete pages, generate booklets, convert images to PDF, change or standardize paper size, add, edit or remove metadata, detect text in images through OCR, and compress files to reduce their size. The homepage describes the software as free and open-source, and the site is presented in French.
