Free Instagram Thumbnail Maker Online

Free YouTube Thumbnail Maker — Video & Shorts

Creating great Instagram graphics is essential for standing out in a crowded feed. Whether you're making a promotional post, a Story announcement, or a Reels cover, our free Instagram thumbnail maker gives you 15 preset gradient templates, custom text layers with full font and colour control, and background image upload — all without any signup or watermark.

Instagram Post thumbnails must be 1080×1080 pixels (square format). Instagram Story and Reels covers must be 1080×1920 pixels (9:16 vertical format). Our tool supports both formats with a simple toggle at the top of the page.

Instagram Graphic Best Practices

• Use bold, readable fonts — text must be legible on mobile screens
• Keep text minimal — 1-2 lines maximum for Posts, 3-4 for Stories
• Use high contrast between text and background for accessibility
• Leave safe margins — keep important content away from the edges
• Use consistent branding colours across all your posts
• For Stories, keep key content in the middle third — avoid the top and bottom UI areas
• Square posts (1080×1080) take up more feed space than landscape posts
