常见问题
What is a social media image cropper?
A social media image cropper formats an image to platform-specific dimensions so posts, banners, and thumbnails display cleanly.
What size should Instagram images be?
Instagram square posts commonly use 1080 by 1080 pixels, portrait posts use 1080 by 1350 pixels, and stories use 1080 by 1920 pixels.
What size should YouTube thumbnails be?
YouTube thumbnails commonly use 1280 by 720 pixels, which is a 16:9 aspect ratio.
What is the difference between fit and crop?
Fit keeps the whole image visible and may add empty space. Crop fills the target size and removes anything outside the selected frame.
Can I use one image for multiple platforms?
Yes, but each platform may need a different crop or final size to avoid awkward automatic cropping.
Are my images uploaded or stored?
The image is processed in your browser whenever possible, and Unite.AI does not store the selected image.
Why do social platforms crop images differently?
Each platform has different feed, profile, banner, and video surfaces, so the same image may be reframed in different places.
