FAQ

Why are there gaps between slices?

If the original dimensions are not divisible by the grid, up to 1 pixel may be discarded per slice — usually invisible.

Does it support transparent PNG?

Yes. Transparency is preserved; output is PNG format.

Will large images lag?

Images up to 5000×5000 are smooth in browsers. For larger ones, compress first with the Image Compressor.
