About Email HTML Generator

The Email HTML Generator turns a dropped image into email-safe HTML: a table layout with inline styles and Outlook-friendly attributes, previewed before you copy. It is for developers building HTML emails that render across stubborn clients.

Email clients ignore much modern CSS, so images need table-based, inline-styled markup. Generating it locally produces compatible HTML without trial and error.

Best practices

Tips for best results

  • Keep styles inline, since many email clients strip style blocks.
  • Always set alt text, as images are often blocked until the reader allows them.
  • Test the email in the clients your audience actually uses.
Common mistakes to avoid

Pitfalls to watch for

  • Relying on modern CSS that many email clients silently drop.
  • Forgetting alt text, which shows when images are blocked by default.
  • Skipping width attributes, which some clients need to size images correctly.

FAQ

Common questions

Many email clients, especially Outlook, have limited CSS support. Tables with inline styles render far more consistently than modern layout techniques.
Support is mixed — some clients (notably Gmail) block data URI images. The generator includes them for clients that allow it; for broad reach, host the image and swap the src.
It uses presentational attributes (width, border, cellpadding) and inline styles, plus display:block to avoid gaps, which Outlook respects.
No. The HTML is generated entirely in your browser.
