Frequently Asked Questions

What Word formats are supported?

Only modern .docx files (Word 2007 and newer) are supported. Legacy .doc files use a binary format and aren't supported client-side. If you have .doc files, open them in Word and save as .docx first.

Is my Word document uploaded anywhere?

No. Conversion happens entirely in your browser using Mammoth.js. Your DOCX file never leaves your device, making this safe for confidential contracts, personal documents, and internal reports.

What formatting is preserved?

Headings (H1-H6), paragraphs, bold, italic, underline, bullet and numbered lists, tables, hyperlinks, and embedded images are preserved. Complex features like text boxes, shapes, and macros are not supported.

Can I customize the PDF output?

Yes. Choose page size (A4, Letter, Legal), orientation (portrait/landscape), margin size (10-25mm), and custom filename. The preview shows exactly how the PDF will look.

What's the file size limit?

Tested up to 25MB DOCX files with 200+ pages. Larger files may work but processing takes longer. Your browser's memory is the real constraint.
