Different platforms require specific banner, avatar, and post dimensions (e.g. YouTube banner 2560x1440, Instagram post 1080x1080). Our resizer lets you input exact pixels with bicubic interpolation algorithms.

Frequently Asked Questions (FAQ)

Downscaling reduces pixel count while maintaining crispness. Upscaling beyond 200% will interpolate pixels smoothly, though original resolution sets the upper limit of detail.
