File Size, Performance, and Quality Tips

  • Exports: Avoid giant images inside DOCX to prevent bloated PDFs. Optimize images before embedding.
  • PDF optimization: Use balanced compression to reduce size while preserving legibility.
  • HTML performance: Compress images, lazy-load where possible, and use Base64 only for tiny, repeated assets (icons/logos).

Accessibility and Inclusivity Basics

  • DOCX: Use heading styles and alt text; exports to tagged PDF more cleanly.
  • PDF: When exporting, enable tagging, set language, and ensure contrast. Run an accessibility check when available.

Security and Privacy

  • Links & QR: Host sensitive content appropriately and control access; ensure public links don’t expose private data.

Common Mistakes to Avoid

  • Sending DOCX as “final” and seeing layout shifts on the recipient’s device.
  • Emailing a 20MB+ PDF without compression, causing bounces or slow downloads.
  • Embedding uncompressed images in DOCX, leading to oversized PDFs on export.
  • Using Base64 for large images, bloating HTML.

Quick Decision Matrix

  • Need a perfect, printable layout? Choose PDF.
  • Need collaboration and revisions? Choose DOCX.
  • Need web visibility and easy updates? Choose HTML.

FAQs

Is PDF or DOCX better for resumes?

DOCX is best for drafting and edits; PDF is best for final submission to preserve layout and fonts.

Why do my PDFs get rejected by email?

Can I make a PDF accessible quickly?

Start with structured DOCX (headings, alt text), then export to a tagged PDF and apply balanced compression.

When should I use HTML instead of PDF?

Use HTML for content that should rank in search, be responsive by default, and update frequently.
