浏览器内运行这个工具能做什么
Edit one browser-decodable image with numeric crop controls, 90-degree rotation, horizontal or vertical flip, output dimensions, format, quality, and a live local preview.
Every apply action starts from the selected original, so the numeric recipe is reproducible and does not accumulate repeated lossy encodes.
这个工具可以完成什么
Crop in source pixels, rotate 90 degrees, resize to 1600 pixels wide, and export WebP.
依赖结果前需要检查什么
- Animated input is flattened and unsupported color profiles may be normalized by Canvas.
- Canvas export can remove source metadata; keep the original if metadata or archival fidelity matters.
如何使用
- 1
Choose one PNG, JPEG, or WebP image.
- 2
Enter crop offsets and size, then choose rotation and flip options.
- 3
Set final dimensions, output format, quality, and JPEG background.
- 4
Generate the preview, inspect the result, and download a new file.
使用场景
Rotate, crop, resize, and export a shareable copy without switching tools.
Crop to a fixed composition and export WebP at a controlled quality.
常见问题
Does applying controls repeatedly reduce quality?
Each generation decodes the original source again, so changing controls does not repeatedly re-encode the previous preview.
Can it preserve animation?
No. Animated GIF or WebP input is flattened to the browser-decoded frame.
How is the crop measured?
Crop values are source-image pixels before rotation and output resizing.
