Formatting issues are the biggest pain when converting PDFs. Here is what actually causes them — and how our browser-based converter handles it.
Why PDF to Word Conversion Loses Formatting
PDF is a fixed-layout format. It stores text as positioned glyphs on a page — there is no concept of "paragraph" or "table" baked in. Word (.docx) is a flow-layout format where content reflows based on margins and font size. Bridging the gap between these two models is where most converters struggle.
What Our Converter Preserves
Our PDF to Word converter runs entirely in your browser using pdf.js for parsing. It reconstructs the following:
- Paragraphs — text runs with consistent font and size are merged into Word paragraphs
- Tables — detected using column-gap heuristics (a 3.5× font-size threshold between columns)
- Font sizes — mapped to Word heading levels (h1/h2/h3) or body text
- Bold & italic — font weight and style flags are preserved directly
What Cannot Be Preserved
Some things are genuinely impossible to reconstruct from a PDF:
- Multi-column layouts — the text order in the PDF stream may not match reading order
- Images with text overlays — embedded image text is not extractable without OCR
- Custom fonts — if the font is embedded in the PDF but not installed on your system, Word will substitute it
Tips for Best Results
- Use text-based PDFs, not scanned images. If you can select text in the PDF, conversion will be accurate.
- For complex layouts, convert page by page if your PDF tool allows it.
- After conversion, use Word's "Keep Source Formatting" paste option if you're moving content elsewhere.
Privacy Note
Every conversion happens locally in your browser. Your PDF is never sent to a server. This means there are no file size limits imposed server-side — processing speed is limited only by your device.
