Will Instagram show my grid in the right order?
Yes, as long as you upload each tile in the correct order — the 3x3 grid produces tiles left-to-right, top-to-bottom, matching how you should post them (in reverse, since Instagram profiles show newest first).
Does splitting reduce image quality?
No. Each tile is cropped directly from the original pixel data with no re-compression beyond the final PNG export.
Can I download just one tile instead of the whole set?
Yes. Each tile has its own download button, or you can download all of them at once as a single ZIP file.
