Frequently Asked Questions
What is an image thumbnail?
A thumbnail is a smaller version of an image, typically used for previews, icons, avatars, and faster loading times. Common sizes include 32x32, 64x64, 128x128, and 256x256 pixels.
Why generate multiple thumbnail sizes?
Different platforms and devices require different image sizes. App stores need various icon sizes, websites use different thumbnails for responsive design, and social media platforms have their own requirements.
What image formats are supported?
You can upload JPG, PNG, WebP, and GIF images. The output can be saved as PNG, JPG, or WebP format. PNG is recommended for images with transparency.
