Drag and drop, click to browse, or paste a URL. Batches take up to 20 files at once - 230+ input formats across video, audio, image, document, and archive types.

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is an LWP file?

The LWP format represents documents created by Lotus Word Pro, a word processor component of the IBM Lotus SmartSuite. These files utilize a proprietary binary structure to store rich text, page layouts, and 'SmartMaster' formatting templates. Developed by the Lotus Development Corporation (acquired by IBM), the format superseded the earlier SAM and AMI formats, serving as a primary competitor to Microsoft Word in the mid-1990s enterprise market.

How to open an LWP file

Native execution requires the discontinued Lotus SmartSuite software on Windows. For modern environments, LibreOffice Writer includes specific import filters to reverse-engineer and open LWP files, though some complex formatting may be lost. Alternatively, the KeyView file viewer can display contents without editing capabilities.

What is a PDF file?

The Portable Document Format (PDF) is a comprehensive file format, standardized as ISO 32000, designed to present documents consistently independent of application software, hardware, and operating systems. It encapsulates a complete description of a fixed-layout 2D document, including text, fonts, vector graphics, and raster images, based on the PostScript language. Advanced implementations support interactive form fields, JavaScript scripting, 3D objects (U3D/PRC), and various encryption standards.

How to open a PDF file

PDF viewing is natively supported by all major modern web browsers (Chrome, Edge, Firefox, Safari) and most operating systems via built-in previewers. For advanced manipulation, form filling, or pre-press validation, dedicated software such as Adobe Acrobat DC, Foxit Reader, or open-source tools like Ghostscript and Poppler is required.
