Why Does My HTML-to-PDF Conversion Lose Formatting?
Written and fact-checked by The EditPDF AI Team
A PDF is a fixed page size; a browser window is not. Most formatting problems come from that fundamental difference, plus a few common HTML/CSS issues.
Common causes
- ·Fixed pixel-width layouts designed for a wide screen get cramped or cut off at page width
- ·External stylesheets or fonts that failed to load because they required a login or were blocked
- ·CSS that relies on viewport units (vw, vh) which behave differently on a fixed page than a resizable browser window
- ·Elements positioned with absolute or fixed CSS positioning can land in unexpected spots on a paginated page
How to fix them
- 1Use relative or percentage-based widths instead of large fixed pixel values where possible.
- 2Host any custom fonts or stylesheets somewhere publicly reachable, or embed CSS directly in the HTML.
- 3Add explicit print/page-break CSS rules if you need control over where pages split.
- 4Avoid viewport units for layout-critical sizing; use fixed units or percentages instead.
