Pixelhunter is an AI-driven image resizer designed for social media optimization. It processes uploaded images to fit specific platform dimensions through automated cropping and resizing. The tool integrates the Uploadcare Intelligence API for object recognition, ensuring focal points remain intact during adjustments. Supported formats include over 100 sizes for platforms such as Instagram, Facebook, LinkedIn, and Google Ads.

Key operations involve uploading an image file, selecting a target size or platform, and allowing the AI to generate the output. Compression applies automatically to maintain quality without visible artifacts. Free access covers basic usage with limits on batch processing, while paid tiers expand capacity for higher volumes.

Users report positive experiences with speed and accuracy on review sites like Product Hunt, where it scores around 4.4 out of 5. Common praises include the intuitive web interface and time savings over manual tools. Some note occasional delays with complex images due to AI analysis.

Competitors include Canva, which offers broader editing alongside resizing, and ImageKit, focused on API integrations for developers. Pixelhunter differs by prioritizing quick, standalone social media adaptations without additional design features.

For implementation, upload images in common formats like JPEG or PNG. Review the AI-suggested crop before finalizing. Export options provide direct downloads suited to each platform’s requirements. Regular updates add new sizes, keeping pace with social media changes.
