Three Page Size Options

📄 A4 (210 × 297 mm)

The international standard used in most countries outside North America. A4 is the right choice for professional reports, business letters, academic papers, CVs, and any document intended for international audiences or standard office printing.

📃 Letter (8.5 × 11 inches)

The standard US paper size used in North America. Choose Letter when your document is intended for printing or distribution in the United States or Canada, or when submitting to organizations that require US-format documents.

📋 Legal (8.5 × 14 inches)

Common for legal documents, contracts, and official forms in the United States. Choose Legal when your document is a legal agreement, court filing, or any formal document that follows US legal paper conventions.

Why Convert Word to PDF?

Word documents (.docx) are editable by design — fonts, spacing, and layout can shift depending on the version of Word, the operating system, and the fonts installed on the recipient's device. A PDF locks all of this in place, ensuring your document looks identical on every screen and every printer, regardless of the software used to open it.

PDF is also the required format for most official submissions — job applications, university admissions, government forms, legal filings, and contract exchanges all typically require PDF. Converting before sending gives you a professional, tamper-evident document that is universally readable.

Common Use Cases

📋 Submitting CVs and Job Applications

Recruiters and HR platforms almost universally prefer PDF over Word for CVs and cover letters. Converting ensures your carefully formatted resume displays exactly as you designed it, regardless of the software the recruiter uses.

🎓 Academic Submissions

Universities, journals, and scholarship programs typically require PDF submissions. Converting your Word document before submission ensures it meets format requirements and cannot be accidentally edited after submission.

⚖️ Legal and Business Documents

Contracts, proposals, NDAs, and formal agreements are best shared as PDFs to prevent accidental or unauthorized editing. PDF is the standard format for legally binding document exchange.

📊 Sharing Reports and Presentations

Business reports and executive summaries shared as Word files can look different on each recipient's machine. Converting to PDF ensures consistent formatting, correct font rendering, and a professional appearance.

🗂️ Archiving Documents

PDFs are more reliable for long-term archiving than Word files, which depend on Microsoft Office compatibility. Converting documents you need to keep creates a stable, device-independent archive format.
