Email CSS Inliner & Size Optimizer
Inline email CSS and measure the Gmail size impact
Move style rules into elements, preserve responsive enhancements and Outlook structures, then apply conservative email-safe whitespace optimization.
HTML and CSS are sent to the EasyAImail conversion service. Content is not stored, and no external resources are fetched.
Built around the constraints of email HTML
The goal is not maximum compression. It is a stronger inline baseline without breaking email-specific structures.
Keep responsive enhancements
Preserve media queries, dark mode, fonts, keyframes, pseudo rules, and selectors that cannot be safely inlined.
Protect email-specific code
Keep Outlook conditional comments, VML, common template syntax, and client-specific selectors.
Quantify Gmail risk
Compare UTF-8 byte size before and after processing and show the remaining room below 102 KiB.
Inlining does not always reduce size
Repeating declarations across elements can make HTML larger. Preview the result, run compatibility checks, and test representative inboxes before sending.
Email CSS inliner FAQ
Why inline CSS in an email?
Email clients differ in how they support styles in the head. Moving baseline styles onto elements often improves core layout and typography while retained media queries provide progressive enhancement.
Will the tool load external CSS or images?
No. HTML and separate CSS are sent to the conversion service, but it does not request link stylesheets, @import rules, images, fonts, or other external URLs.
Will conservative optimization remove Outlook code?
It does not intentionally remove Outlook conditional comments or rewrite VML, and it avoids aggressive operations such as quote removal, attribute reordering, and URL rewriting.
