What Blog Featured Image Maker does, with a checked example
This tool composes a featured image for a blog post inside the browser: you choose a gradient background, add a title overlay, and optionally include a subtitle or author line, then download a ready-to-use JPEG or PNG. It enforces a fixed canvas ratio, so a title that looks right in the editor also fits the final file. The common surprise is that the canvas is sized for social and listing previews, not for full-width article headers, so text that fills the frame in the editor may be cropped in an OG image.
Worked example
A concrete input and expected output from the current implementation.
Input
Gradient: Sunset (orange #FF7E5F to pink #FEB47B), Title: "5 Ways to Reduce Server Costs", Subtitle: "A practical guide for startups", Brand logo: none
->
Expected output
A 1200 x 630 pixel PNG with a diagonal gradient from #FF7E5F at the top-left to #FEB47B at the bottom-right. The title is centered in white bold type, wrapped as "5 Ways to Reduce" / "Server Costs", with the subtitle "A practical guide for startups" in smaller white text below.
The tool composites the chosen gradient, wraps the title text to the fixed 1200 x 630 area, and exports a single image file. The text wrap is determined by the canvas width and the font size, so a long title breaks into multiple centered lines.
