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.

How the result is produced

1

Fixed canvas and text wrapping

The editor works on a canvas locked to a 1200 x 630 pixel area, the common Open Graph image size. Title text is wrapped automatically at word boundaries to fit the width, and you can adjust font size, weight, and spacing. The preview updates live as you type, so the final export matches what you see.

2

Download and file format

When you click download, the tool renders the current canvas state - gradient, text, and any logo - into a single raster image file, offered as JPEG or PNG. The download is generated entirely in the browser from the in-memory canvas; no server round-trip is involved, and the source image or text never leaves your machine.

Good uses

  • Creating a consistent title-card for a weekly blog series, reusing the same gradient and font settings each week.
  • Generating a 1200 x 630 image to attach as an Open Graph preview so a post link shows a clean title card on social media.
  • Producing a quick thumbnail for a post index page when the article has no in-content hero image suitable for cropping.

Limits and checks

  • The 1200 x 630 canvas is sized for link previews, not for a wide article header; a design that fills the frame will be cropped or look stretched if you use it at a different aspect ratio.
  • A very long title will wrap into many lines, which reduces the space available for the subtitle and may make the overall composition denser than intended. Review the preview carefully to ensure the text remains readable at thumbnail size.
  • The image contains no live text or vector shapes after export - it is a flat raster. You cannot edit the title or gradient later without rebuilding the image in the tool.

Common questions

Can I upload my own logo or background photo?

The tool is built around gradient backgrounds and text overlays, so it accepts image uploads for a logo overlay, but it does not provide photo-editing features. You can place a logo image at a corner, but you cannot crop, filter, or blend a full background photo; use a gradient preset or supply an already-prepared background as a separate layer if your workflow needs that.

Will the downloaded image match what I see in the preview?

Yes, for the standard canvas. The export renders the same canvas state at 1200 x 630, so the text wrapping, gradient, and logo position match the preview pixel for pixel. The only difference is that the downloaded file is flattened - it loses the editable layers, so keep the project settings in the tool if you want to revisit it later without starting over.
