Higher values also trim faint, semi-transparent edge pixels. Use 0 to trim only fully transparent pixels.

FAQ
What pixels get trimmed?
PixelChore scans from every edge and removes rows or columns where pixels are transparent enough to count as empty.
Does this work on JPG images?
JPG does not support transparency, so this tool is best for PNG and WebP files with an alpha channel.
Can I keep a little space around the result?
Yes. Increase padding to add transparent margin back around the detected content.
