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.

Frequently Asked Questions

Use high-quality resampling methods like Lanczos for best results. When downsizing, quality loss is minimal. For enlarging, our AI upscaling can increase size up to 4x while preserving details. Always keep originals and avoid resizing multiple times. For web use, modern formats like WebP maintain quality at smaller sizes.

Instagram posts: 1080x1080px (square) or 1080x1350px (portrait). Facebook cover: 1200x630px. Twitter header: 1500x500px. LinkedIn banner: 1584x396px. YouTube thumbnail: 1280x720px. Our presets automatically apply the correct dimensions for each platform, updated regularly as requirements change.

Yes! Our AI upscaling technology can enlarge images 2-4x while adding realistic details. It works best on photos and natural images. For graphics and logos, vector tracing might be better. The AI analyzes patterns and textures to intelligently fill in missing pixels, creating sharp enlarged images.

Use pixels when you need exact dimensions (web layouts, print sizes). Use percentage for proportional scaling across different sized images or maintaining relative sizes in batch processing. Percentage is ideal when you want to reduce all images by half or double their size regardless of original dimensions.

Aim for widths of 800-1200px for content images, 1920px for full-width backgrounds. Use responsive images with multiple sizes. Enable compression (80-90% quality for JPG). Consider WebP format for 25-35% smaller files. Our web optimization preset balances quality and file size perfectly.
