Frequently Asked Questions
What is a video cover?
A video cover (or thumbnail) is the preview image that viewers see before clicking to watch your video on social media platforms. A good cover attracts more views and engagement.
Why does each platform have different size requirements?
Different platforms have different aspect ratios for their video players. For example, TikTok uses vertical 9:16, while YouTube uses horizontal 16:9. Using the correct size ensures your cover looks perfect.
Is my image private and secure?
Absolutely! All processing happens 100% locally in your browser. Your images are never uploaded to any server. We use client-side processing to ensure complete privacy.
What does the grid splitting do?
Grid splitting divides your cover image into multiple pieces. When posted sequentially on social media, these pieces form a mosaic effect when viewed in your profile grid. This creates eye-catching visual patterns.
How do I choose the right grid size?
Common choices are: 3×3 (9 images) for WeChat Moments, 2×2 (4 images) for quick posts, or 1×1 for a single cover. You can customize rows and columns based on your creative needs.
Can I adjust the crop area?
Yes! Use the cropper tool to drag, resize, and position the crop box. The tool maintains the platform's recommended aspect ratio to ensure perfect results.
What if I use a different ratio than recommended?
The tool will show a warning but still allow you to proceed. However, using a different ratio may cause your cover to be cropped or have borders on the platform, reducing quality.
What's the output format?
You can choose PNG (recommended for quality), JPG (smaller file size), or WebP (modern format). All formats maintain high quality for social media use.
How do I post the grid images?
Download all images as ZIP, extract them, then upload them in order (1, 2, 3...) to your social media platform. When posted, they'll create a seamless mosaic effect in your profile.
