About Pixelhunter
Pixelhunter is a free web tool that resizes one uploaded image into every size needed for social media. A user drops in a file of any dimensions and the tool automatically produces versions for each of the 103 sizes it supports, across platforms such as Facebook, Instagram and Twitter, including profile pictures, cover photos, stories and feed posts.
The AI component is smart cropping. The vendor states that it uses the Uploadcare Intelligence API to recognize objects in a picture and crop around them, rather than cutting from the center. The results can be downloaded all at once, and each format listed on the page comes with a short pro tip about how that placement is typically used, along with the output format and pixel dimensions.
The vendor describes Pixelhunter as free and does not publish paid plans or any pricing page. The page credits Uploadcare as the technology provider and sponsor. It is a focused single purpose utility, suited to marketers and small teams who publish the same artwork on several social channels and want to avoid cropping each image by hand.
