Whether you need 图片 at exact pixel dimensions, scaled to a percentage, or sized for a specific platform, our 免费 图片 resizer handles it all. 上传 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 图片 to the same specifications in one operation. All processing runs locally in your browser, so your 图片 are never uploaded to any server. 下载 individually or as a ZIP file. Completely 免费 with no signup, watermarks, or usage limits.
