PDF Editor is an online AI-powered tool that offers a range of functionalities for editing and managing PDF files. The key features include the ability to add text and images to PDFs, highlight, annotate, and sign documents.

It also boasts the capacity to modify existing text in documents, which sets it apart from many PDF editors. This tool uses AI to enable features like translation, rewriting, and summarizing content with a high degree of accuracy.

It also provides a variety of PDF modification options, including a toolbox to underline, highlight or strikeout text, insert lines and arrows, and a 'whiteout' option that can hide certain content within the PDF.

PDF Editor stands out for its commitment to user privacy, not storing any data for longer than two hours post-editing. It also allows for easy sharing and downloading of edited documents.

Despite its powerful editing capabilities, the platform maintains the integrity of your original files, not leaving any watermark on your documents after editing.

Furthermore, PDF Editor can function as a PDF viewer, affording users the convenience of viewing and editing their PDFs simultaneously.
