Blog Cover Generator

Every article needs a cover image, but it shouldn't take longer than writing the intro. This blog cover generator turns your title into a polished cover image ready for dev.to, Hashnode, Medium, Substack or your own site.

Generate a blog cover in 3 steps

  1. Paste your article title. Add an optional subtitle, like the series name, reading time or a one-line summary.
  2. Pick a preset. Start from a gradient preset and tweak it, or match your brand with custom colors.
  3. Download or copy. Export a PNG, or copy it to your clipboard and paste it straight into your editor.

Covers for every blogging platform

dev.to: covers are cropped wider than the export. Keep text centered and use the 2× export.

Hashnode: the 2× export (1600 × 840 px) matches Hashnode's recommended cover size.

Medium and Substack: use the 3× export for the sharpest result on large screens.

WordPress and Ghost: upload it as the featured image. It also becomes your social share image.

Promo images for your articles

Use the same generator to create promo images for sharing an article on X, LinkedIn or in your newsletter. Change the subtitle to a hook like “New post” or “Part 2” and export again. It takes seconds and stays on-brand.
