Pixelhunter
AI tool that resizes and crops images for 100+ social media formats.
About Pixelhunter
Pixelhunter is a free AI-powered image resizer built for social media and marketing use. Instead of manually cropping a photo for every platform's dimensions, users upload one image and Pixelhunter automatically generates versions sized for more than 100 formats, covering platforms like Facebook, Instagram, Twitter, YouTube, TikTok, LinkedIn, Pinterest, and Snapchat, plus common ad banner and website sizes. The cropping itself is handled by the Uploadcare Intelligence API, which detects the important subject in an image, such as a face, product, or focal object, and keeps it centered in the frame rather than cropping it out, a common problem with simple aspect-ratio cuts. The tool is aimed at social media managers, marketers, and designers who regularly need to publish the same visual across many channels and don't want to resize each version by hand. Pixelhunter runs as a web-based tool with no download required. The site does not disclose pricing details, a company name, or a founding date, and it is unclear whether a paid tier exists beyond the free resizing tool advertised on the homepage.
