Why Sign PDFs Online
This tool places a signature (drawn, typed, or uploaded) onto a PDF document. It matters because printing, signing by hand, and re-scanning a document just to add a signature is slow and often impractical when everything else about the workflow is digital. It's a particularly common need for PDF, since PDF is a format where file size usually comes from embedded images (scanned pages, high-res photos) rather than the text content itself.
PDF files don't handle this natively without dedicated software — this tool places a signature (drawn, typed, or uploaded) onto a PDF document directly in your browser instead, accounting for the fact that PDF is a format where file size usually comes from embedded images (scanned pages, high-res photos) rather than the text content itself.
Whenever you need to add a digital signature to a PDF file specifically because signing a contract, form, or agreement without printing and scanning, this is the direct way to do it without extra software — especially relevant here since PDF is a format where file size usually comes from embedded images (scanned pages, high-res photos) rather than the text content itself.
