Free Carousel Safe Zone Checker
See exactly where each platform's buttons and captions cover your slide, so your hook and key text never get hidden. Upload a slide and check Instagram, TikTok and LinkedIn.
Free and instant. Your image stays in your browser — nothing is uploaded.
Why use it
Stop hiding your text
Platform UI — captions, action rails, page dots — sits on top of your slide. This shows you where, so nothing important lands under it.
Every platform
Switch between Instagram, TikTok and LinkedIn safe zones, each at the right aspect ratio.
Private by default
The check runs entirely in your browser. Your slide is never uploaded anywhere.
How it works
- Pick a platform.
- Upload one of your slides.
- Keep important text inside the green safe area.
FAQ
What is a carousel safe zone?
It is the part of your slide that platform UI never covers. Captions, like and share buttons, and page indicators sit on top of your image, so text outside the safe zone can get hidden.
Is my image uploaded anywhere?
No. The checker runs entirely in your browser; your image never leaves your device.
Which platforms are covered?
Instagram, TikTok and LinkedIn, each at its typical aspect ratio with the zones their UI overlaps.
