Foxit Reader is a multilingual freemium PDF tool that can create, view, edit, digitally sign, and print PDF files.[3] Early versions of Foxit Reader were notable for startup performance and small file size.[citation needed] Foxit has been compared favorably toAdobe Reader.[4][5][6] The Windows version allows annotating and saving unfinished PDF forms, FDF import/export, converting to text, highlighting and drawing.
