Open and convert old documents, spreadsheets, presentations, and images — including WordPerfect, XPS, Lotus, and HEIC — to modern formats offline.

Founder story
Legacy File Converter exists because most teams do not have one broken format — they have a drawer full of them. Green 18 combined years of converter work into a single offline tool.
