SimplePDF Chrome extension

SimplePDF (also listed as PDFly) lets you fill out forms, sign, and edit PDF files directly in the tab where they're already open, positioning itself around privacy compared to cloud-upload PDF tools. It's best for people who want quick PDF edits without switching apps. The catch: it still requests broad host permissions across all sites to detect PDF files.

What SimplePDF does

SimplePDF, listed in its own manifest as PDFly, adds a toolbar for filling, signing, and editing PDFs right where they open, instead of requiring you to upload the file to a separate website. It also activates on PDF links from services like Google Drive, Dropbox, SharePoint, and OneDrive, plus PDF results in Google and Bing search.

SimplePDF free vs paid

SimplePDF describes itself as a tool that respects your privacy while letting you fill and sign PDFs for free from within the browser. Check the extension's own site for any details on premium features beyond its core fill, sign, and edit toolset.

Is SimplePDF safe?

The extension requests permissions including storage, tabs, notifications, contextMenus, and debugger, along with access to all URLs so it can catch PDF files wherever they appear. The debugger permission in particular is more powerful than most PDF tools use, so it's worth reviewing the request before installing if you're cautious about extension permissions.
