QUICK ANSWER
imageTool detects separate visible regions in a transparent PNG, crops them into individual images and exports them at their original size or on a consistent fixed canvas.

- Adjust the alpha threshold, merge gap and minimum region size
- Choose output size, padding and scaling, then download the results
Key features

- Fine, standard and nearby-merge modes

FAQ
About the Image splitter
Why did the tool find only one image?
The objects may touch or the merge gap may be too large. Reduce the gap and try fine split mode.
Can every result be exported at 512×512?
Yes. Choose fixed size, enter 512×512, then adjust padding and alignment.
Does splitting upload the source image?
No. Detection and export run entirely in the browser.
