Why Word to PDF Conversion Fails in Production

Most developers lose hours debugging broken DOCX to PDF conversions. Fonts disappear, tables overflow, images shift—and you're stuck manually fixing files or fielding angry customer tickets.

Broken Layouts

Tables split across pages, margins collapse, footers vanish—your branded reports look unprofessional.

Font Substitution Hell

Custom fonts get replaced with Arial, breaking your brand guidelines and legal compliance.

Hours of Manual Work

You're manually regenerating PDFs, adjusting Word styles, and firefighting production bugs.

FAQ: Word to PDF Conversion

Does the API preserve custom fonts and styles? ▼

Yes. The API embeds all fonts used in your DOCX file, including custom brand fonts. PDFs render identically on all devices without font substitution.

What happens to tables and images in the conversion? ▼

Tables and images maintain their exact layout, size, and positioning. Multi-page tables split cleanly, and images stay at 300dpi resolution for print quality.

Can I convert password-protected Word files? ▼

Yes. Pass the password in the API request, and we'll decrypt and convert the file. The output PDF can also be password-protected if needed.

Up to 100MB per file. For larger files, contact support for enterprise limits. Most 100-page reports with images convert in under 2 seconds.
