4 Free Developer Tools I Built for Better Social Media Presence

#webdev #tools #seo #productivity

If you've ever shared a link and the preview looked terrible (or was missing entirely), these tools are for you. I built them all as free, no-signup-needed web tools.

1. OG Tag Checker

What it does: Paste any URL and instantly see how it looks when shared on Twitter, Facebook, and LinkedIn. Shows all detected meta tags and warns about missing ones.

Why it's useful: Social crawlers are picky. Missing an og:title? Your link shows up as a blank card. Wrong image dimensions? It gets cropped awkwardly. This tool catches all that before you share.

2. Favicon Generator

What it does: Enter 1-2 letters, pick colors and shape, download favicons in all sizes (16x16 to 192x192) with ready-to-paste HTML tags.

Why it's useful: Every new project needs a favicon. Instead of opening Figma or searching for generators with ads, this generates all sizes in one click. Client-side only — your data never leaves your browser.

3. Social Media Image Resizer

What it does: Upload any image, pick a platform preset (OG, Twitter, Facebook, Instagram, YouTube, Pinterest), and download the correctly sized version.

Why it's useful: Every platform has different image dimensions. This tool has all the 2026 presets built in. No more googling image sizes.

Presets include: OG Image (1200x630), Twitter Card (1200x628), Facebook Cover (820x312), Instagram Post (1080x1080), YouTube Thumbnail (1280x720), and more.

4. OG Image Playground

What it does: Design Open Graph images live with 10 themes. Get a URL you can use directly as your og:image meta tag.

Why it's useful: Instead of designing OG images in Figma for every page, you get a URL that generates them dynamically. Change the title parameter and the image updates.

10 themes: gradient, minimal, dark, branded, sunset, ocean, forest, mono, neon, warm.
