Convert Gmail to PDF locally is a Firefox extension designed to enhance the email experience by allowing users to convert their emails into PDF documents directly from the Gmail interface. This tool features two distinct buttons: an orange button for distraction-free PDFs and a blue button for standard PDF formats. Users can also convert multiple emails at once by selecting threads and utilizing the toolbar action button.

The extension prioritizes user privacy by performing all conversions locally, using the jsPDF library, thus avoiding any external server interactions. The simple mode strips away distracting elements for a cleaner reading experience, while the normal mode retains the standard email format. Recent updates include filename customization, options to hide buttons, and improved font detection for enhanced document presentation.
