Why a .docx File Looks Different on Every Device
A Word document isn't a fixed, final image of a page — it's a set of instructions (fonts, spacing, layout rules) that Word interprets fresh every time the file is opened. If the recipient's computer doesn't have the exact same font installed, or uses a different Word version, or opens it in a different app entirely, those instructions get interpreted slightly differently every time. The document technically "works," but it doesn't necessarily look the same.
PDF solves this by baking in the exact visual result once, rather than shipping instructions to be re-interpreted. That's precisely why PDF is the standard, expected format for job applications, official submissions, and anything meant to be printed exactly as designed.

Final, fixed visual result — identical everywhere
.doc vs .docx
.doc is the older Word format used before Word 2007, built on a proprietary binary structure. .docx is the modern XML-based format used since — more efficient, and the format most current conversion tools expect. Most modern converters only accept .docx, so a .doc file typically needs to be opened in Word or Google Docs and re-saved as .docx before it can be converted.

What Survives a Conversion, and What Doesn't
| Preserved | Not Preserved |
|---|---|
| Headings and paragraph text | Custom fonts not available in the browser |
| Bold, italic, basic text styling | Headers, footers, page numbers from Word |
| Bullet and numbered lists | Tracked changes and comments |
| Basic tables | Complex multi-column layouts |
| Embedded images | Exact pixel-for-pixel Word page breaks |
For most everyday documents — reports, letters, resumes, assignments — this list covers everything that genuinely matters. For heavily designed documents relying on custom layouts, expect to review the preview carefully before sending it anywhere important.
Why Fonts Sometimes Render Differently
A browser-based converter renders text using fonts available to the browser itself — if the original document used a custom or licensed font not accessible in that environment, the converter substitutes a similar-looking font instead. This is a rendering limitation, not a bug, and it's exactly why checking the live preview before finalizing matters most for documents with unusual or branded typography.

Frequently Asked Questions
PDF ensures the document looks identical on every device, unaffected by the recipient's fonts, Word version, or software. It's the standard format for job applications and official submissions.
.doc is the older Word format before Word 2007. .docx is the modern XML-based format used since. Most current tools only accept .docx.
Headings, bold/italic text, bullet lists, basic tables, and images are generally preserved. Custom fonts, headers/footers, tracked changes, and complex layouts may not carry over exactly.
Not directly. First download the Google Doc as .docx via File then Download then Microsoft Word, then upload that file to convert.
The converter renders using fonts available to the browser, substituting a similar font if the original custom font isn't accessible — check the preview for unusual typography.
No, not directly. Remove the password protection in Word first, then convert the unprotected file.
