Aspect ratio is the proportional relationship between an image's width and height. Common ratios include 1:1 (square), 16:9 (widescreen),4:3 (standard), and 3:2 (photography).
Enable "Lock Aspect Ratio" to maintain the original proportions when changing dimensions. This prevents distortion and keeps images looking natural.
All resizing operations happen directly in your browser without any server involvement. Your images stay on your device—nothing is uploaded, stored, or shared. Instant results with complete privacy.
When scaling down images, quality is typically preserved well. When scaling up (enlarging), some quality loss is inevitable. Our tool uses high-quality interpolation algorithms to minimize quality loss. For best results, avoid enlarging images more than 2x their original size.
Aspect ratio is the proportional relationship between width and height (e.g., 16:9, 4:3, 1:1). When locked, changing one dimension automatically adjusts the other to maintain proportions, preventing image distortion.

Yes! Use our Batch Processor tool to resize multiple images at once. You can apply the same dimensions to up to 50 images simultaneously, saving time for large projects.
There's no strict limit, but very large images (over 50 megapixels) may take longer to process depending on your device. Since all processing happens in your browser, performance depends on your device's capabilities.
No. All resizing happens directly in your web browser. Your images never leave your device, are never stored on servers, and remain completely private. Processing is instant because there's no upload/download time.
