Resize Features
Advanced resampling algorithms including Lanczos, bicubic, and bilinear ensure optimal quality when scaling. AI-powered upscaling can enlarge images up to 4x while preserving details. Smart downscaling maintains sharpness and prevents artifacts, perfect for any size adjustment needs.
Maintain original proportions or choose from standard ratios like 16:9, 4:3, 1:1 square, or custom dimensions. Lock aspect ratio to prevent distortion, or freely adjust width and height independently. Smart cropping options help when changing aspect ratios to avoid stretching.
One-click presets for social media platforms, devices, and standard uses. Instagram posts and stories, Facebook covers, Twitter headers, YouTube thumbnails, phone wallpapers, and more. Each preset applies optimal dimensions and compression for the target platform.
Resize multiple images simultaneously with consistent settings. Perfect for e-commerce catalogs, photo galleries, or web optimization. Apply the same dimensions, maintain aspect ratios, or use percentage scaling across entire folders. Export with organized naming conventions.
