Whether you need images at exact pixel dimensions, scaled to a percentage, or sized for a specific platform, our miễn phí image resizer handles it all. Upload JPG, PNG, WebP, GIF, or any other format and set your target dimensions with pixel-perfect precision. The resampling engine uses advanced algorithms to maintain sharpness, color accuracy, and detail at any target size. Lock aspect ratios to prevent distortion, use predefined presets for popular platforms, or enter custom dimensions for unique requirements. The tool also supports batch processing — resize hundreds of images to the same specifications in one operation. All processing runs locally in your browser, so your images are never uploaded to any server. Download individually or as a ZIP file. Completely miễn phí with no signup, watermarks, or usage limits.
