About HTML Image Generator

The HTML Image Generator turns a dropped image into a ready-to-paste img tag with a data URI source, letting you set alt text, dimensions, and lazy loading. It is for developers inlining a small image directly into markup.

Inlining an image as a data URI removes a separate request and keeps the asset self-contained. Building the tag locally means the image is never uploaded, and the attributes are filled in for you.

  2. Set the alt text, dimensions, and lazy-loading option.

Best practices

Tips for best results

  • Inline only small images; link larger ones as normal files for caching.
  • Always provide meaningful alt text unless the image is purely decorative.
  • Set width and height to reduce layout shift as the page loads.
Common mistakes to avoid

Pitfalls to watch for

  • Inlining large images, which bloats the HTML; data URIs suit small assets.
  • Leaving alt text empty, which harms accessibility unless the image is decorative.
  • Inlining the same image on many pages instead of caching a shared file.

FAQ

Common questions

A complete <img> element whose src is a Base64 data URI of your image, plus the attributes you choose such as alt, width, height, loading, decoding, class, and id.
Data URIs avoid an extra request and are great for small icons or email. For large images, a normal file URL is usually better for caching.
Alt text is strongly recommended for accessibility and SEO. The generator includes the attribute even when empty so you remember to fill it in.
No. Everything is generated in your browser; the image never leaves your device.
Private by design

This runs entirely in your browser

No file or text you enter here is uploaded. Encoding and decoding happen on your device using native browser APIs — close the tab and nothing remains on a server.
