Convert Word to PDF Online — Free DOCX to PDF Converter
Convert Microsoft Word documents (.docx) to PDF format. Preserve images, tables, headings, and text formatting — all in your browser with complete privacy.
Why Choose Our Word to PDF Converter?
Complete Privacy
Your Word documents never leave your device. Cloud converters upload files to servers. LocalPDF converts locally for maximum security.
Images & Tables Preserved
Unlike text-only converters, LocalPDF keeps your embedded images, tables, and visual formatting intact in the PDF output.
Two Conversion Modes
Choose 'With Formatting' for visual documents with images/tables, or 'Text Only' for faster conversion and smaller file size.
Unicode Support
Full support for Cyrillic, extended Latin (ā, ē, ī, ģ), Greek, and all international characters. Works with documents in any language.
Quality Control
Select output quality from Standard to Maximum based on your needs — balance between file size and visual fidelity.
No File Size Limits
Convert Word documents of any size. Cloud tools often cap uploads at 10-50 MB. LocalPDF has no restrictions.
