How it works

Build once, keep your files

The maker uses pasted URLs for images and embeds so the save and final exports stay portable single-file documents.

Set the public page

Start the same way the original tool worked: name, profile image, background image or color, then font.

Paste image URLs instead of uploading so exports stay one file

Use the background tools for darken, blur, and grain

Keep the page itself centered while you edit

Google Sites publishing

Paste the final file as a full-page embed

Open Google Sites, create a blank site, then add a full-page embed.
Download Final from the maker, open the text file, copy all of the HTML, and paste it into Embed from code.
Make that embed page your home page, publish, then reuse Download Final whenever you update your links.
