Why anyone needs a blank PNG
Genuinely empty
Every pixel has zero alpha. There is no white fill and no baked-in checkerboard — the checkered pattern you see in the preview is the page drawing it behind the result so you can tell transparent from white. The file itself contains nothing.
Exact dimensions
The point of a blank PNG is almost always its size: reserving a space, forcing a layout to a known height, matching an asset slot. Set the numbers here and leave the height at zero for a square.
Spacers and placeholders
A transparent PNG of a known size is still the reliable way to force spacing in email HTML, where CSS support is unpredictable. It is also the honest placeholder in a mock: it occupies the slot without pretending to be content.
A canvas to build on
Use it as a base to composite onto in another tool when you need an exact canvas size and do not want to crop or pad an existing image into shape.
Keep it PNG
Converting to JPG fills the whole thing with white and there is nothing else in the file, so you end up with a plain white rectangle. If it must be a JPG, use the solid colour generator instead.
Working with blank PNGs
The checkerboard is not in the file
It is drawn behind the result so you can tell transparent from white. The downloaded PNG contains nothing at all.
Never convert it to JPG
JPG has no alpha, so the whole thing flattens to white and you lose the only property it had.
Size is the whole point
A blank PNG exists for its dimensions. Set them deliberately rather than resizing one afterwards.

Describe the edit in your own words
Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
