Features
LegacyFileConverter is a Swiss-army knife for old files — built to open what nothing else will, and convert it to something you can actually use today.
One app for every legacy format
Documents, spreadsheets, presentations, and images — dozens of old and modern types handled by a single converter. No more hunting for a separate tool for every file type you run into.
Smart format bucketing
Old spreadsheets go to XLSX, old word-processor files to DOCX, presentations to PPTX, and images to JPG or PNG — the right modern target is suggested automatically for each file.
Universal output formats
Send anything to a universal PDF for preservation, Markdown (.md) for AI and plain-text workflows, or HTML for the web — so your content is readable anywhere, for years to come.
100% offline & private
Conversion runs entirely on your PC. Files are never uploaded, there is no account, and it all works on a machine with no internet connection. Ideal for confidential and regulated work.
Right-click in Windows Explorer
Convert any supported file — or an entire folder — straight from the Windows right-click menu, without opening the app first. Quick conversions are one click away.
Batch & folder-watch automation
Convert thousands of files at once and mirror your folder structure. Point folder-watch at a directory and new files dropped into it convert automatically.
Content-based detection
Files with the wrong or missing extension are still recognized by their actual contents, so a mislabeled .txt that is really a WordPerfect file won’t slip through.
Look inside archives
Point it at a ZIP, 7z, RAR, TAR, GZ, BZ2, XZ, LZIP, or Zstandard archive and it converts the legacy files trapped inside — to a folder, your chosen destination, or back into a fresh zip. The original archive is never touched.
No original application required
You do not need WordPerfect, Lotus, Quattro Pro, Works, Photoshop, or any vintage software installed. The conversion engine is built right into the app.
