Share image sizes cheat sheet

One image rarely fits every feed. Type your copy once, pick a template, and export a pixel-perfect PNG for each platform below — everything is rendered locally in your browser, so nothing is ever uploaded.

PlatformUseSizeRatio
Big type winsThumbnails are tiny in feeds. Keep one short headline and let it fill the canvas — ShareForge auto-fits the font size for you.
Show the productA real screenshot in a browser frame consistently outperforms abstract art. Paste yours in, no design skill needed.
One accent colorPick your brand color once — gradients, glows and badges across all templates follow it automatically.
Export the setPost everywhere at launch: batch-export all 8 sizes with one click and drop each file into the right platform.

FAQ

What sizes do social platforms need for share cards?

X/Twitter posts work best at 1200×675 (16:9), generic Open Graph link cards at 1200×630, WeChat Official Account covers at 900×383 (plus 383×383 for secondary posts), Xiaohongshu/RED at 1242×1656, Instagram at 1080×1080, LinkedIn at 1200×627 and Douyin/Video covers at 1080×1440. All ship as one-click presets here.

Is it free? Do I need an account?

100% free, no signup, no watermark, no export limits.

Are my screenshots uploaded anywhere?

No. Everything renders locally with HTML5 Canvas — your text, screenshots and logo never leave your device, and the page keeps working offline.

Can I export all platform sizes at once?

Yes — type once, click “Export all 8 sizes”, and you get one ready-to-post PNG per platform. Single-size download and copy-to-clipboard are also available.

What format are the exports?

Lossless PNG files at each platform's exact pixel dimensions, ready to upload as-is.
