Empty, see-through space added around a cut-out, logo or product shot — on every side or just one, in pixels or percent, measured from what is actually visible.
Opens with 10% transparent margins on every side, PNG out, on a checkerboard so you can see the empty region. “Pad around what is visible” measures from the content, not the file edge.
What this does to your file
The picture is drawn into a bigger canvas at its own size; every new pixel is left empty. No fill, no seam to feather, and nothing about the original pixels changes — including the soft edges of a cut-out, which keep their alpha exactly.
| Padding | Canvas | Empty |
|---|---|---|
| 10% all round | 1,440 × 1,440 | 31% |
| Square from 3:2 | 1,200 × 1,200 | 33% |
| Icon, 20% all round | 716 × 716 | 49% |
The awkward questions
How do I add transparent padding to a PNG?
Open it here: the page starts with 10% of empty space on every side and PNG output. Change the four margins in pixels or percent, or pick a shape (1:1 for a marketplace square) and the short sides grow with transparent canvas.
My cut-out already has a see-through border. Will it be padded twice?
Use “Pad around what is visible”. It reads the alpha channel, finds the box the visible pixels sit in, and adds only what is needed to give that content the space you ask for. Nothing is cut from the picture, so a side that already has more see-through border than you asked for keeps it, and the panel says which.
Why did my padding come out white?
JPG has no way to record an empty pixel, so it writes white. Save as PNG or WebP — this page starts on PNG for that reason — and the transparency survives.
Is the AI fill available here?
No, deliberately: on this page transparency is the point, so there is nothing to generate.
Is my file uploaded?
No. It is opened and padded by this tab.
