使用步骤

- Set DPI: Pick resolution: 150 DPI (standard preview), 200 DPI (sharp screen display), or 300 DPI (print-ready). Higher DPI = larger files but sharper output.
- Choose Output Mode: Either white background (standard document rendering) or transparent (useful for embedding designs). PNG quality is lossless by default.

常见问题
Can I convert Word to PNG at 300 DPI?
Yes — our Word to Image tool supports up to 300 DPI PNG output. Drop your .docx, pick 'PNG' as format and '300' as DPI, click 'Render'. ZIP downloads with all 300 DPI PNGs, ready for print or high-resolution digital use.
Is the PNG quality lossless?
Yes — PNG is always lossless. The output preserves every pixel exactly. For even smaller files with minimal quality loss, choose JPG at quality 85+ instead. Use PNG for graphics and text-heavy content; JPG for photo-heavy content.
How big is the output for a 10-page document at 300 DPI?
Each page at 300 DPI for Letter/A4 is roughly 2550×3300 pixels — about 1-3 MB per page for text-heavy content, 5-15 MB per page for image-heavy pages. A 10-page text-only document: 10-30 MB total.
Will my Word document be uploaded?
No. mammoth.js processes everything in your browser. Whether the document contains confidential business plans, unpublished research, or personal content, it stays on your device.
What about complex Word formatting?
We preserve text formatting (bold, italic, headings, lists, tables). Complex Word features like SmartArt, charts, and embedded objects render as flattened images. For purely design-focused Word documents, our PNG output may differ slightly from Word's rendering — use our PDF tool instead for exact Word-like output.
