Splitting 16:9 into three tiles is a crop, not a new render
The tool slices one image into three panels for carousels that expect equal tiles. Pixels outside the crop rectangles are discarded. It does not upscale a small photo into print quality.
Alignment
If a face sits on a cut line, move the source or choose a different crop origin. Export all three files together so social apps do not recompress one tile more than the others. Local processing means the photo is not uploaded to Toolioz when that label is present.
Worked examples
1080p source
A 1920×1080 image split into three vertical panels yields three 640×1080 images if the split is even and unpadded. Confirm the on-page pixel readout; padding for safe zones can change that.
