What this tool does
Pixel-precise crop via X/Y origin and width/height (no drag box). Handy when you need exactly 1080×1920 from a larger shot.
How to use
- Upload; crop size defaults to full image.
- Enter origin X/Y and crop width/height (0,0 is top-left).
- Apply crop, then download PNG.
FAQ
Can I crop to 16:9?
No ratio presets — compute width/height yourself (e.g. 1600×900).
What if the crop exceeds the image?
Overflow becomes transparent. Keep origin+size inside the image bounds.
