I had the same issue and ended up using SignOnlinePDF
https://signonlinepdf.com/sign/windows/ which turned out to be exactly what I needed. It works right in the browser on my Windows laptop — no downloads or installations necessary. You just upload your PDF, add your signature using a mouse, keyboard, or even an uploaded image, and then place it exactly where it needs to go in the document. I especially appreciated the Google Drive integration, which saved me time when working with files stored in the cloud. It’s fast, secure, and incredibly easy to use — definitely my go-to now whenever I need to sign PDFs on Windows.
