How to resize an image to 15 KB
- Choose your photo. JPG, PNG and WebP all work, including photos straight from your phone.
- Check the size. 15 KB is already selected; add a width in pixels if the form asks for exact dimensions.
- Resize. The new JPG downloads straight away, with a preview, its size and its dimensions.
We tested it: four photos resized to 15 KB
Tested on October 28, 2026, with no width typed, on a face-and-shoulders photo (1855 × 2379 px, 1.2 MB), a landscape phone photo (2880 × 1920 px, 2.3 MB), a signature photographed on paper (73 KB) and a phone photo of a document (846 KB).
| Photo | After | Pixels | Quality |
|---|---|---|---|
| Face photo | 15 KB | 389×499 | 61% |
| Landscape | 15 KB | 387×258 | 64% |
| Signature | 15 KB | 1440×560 | 48% |
| Document | 15 KB | 285×403 | 67% |
At 15 KB the face photo kept 389 × 499 px at quality 61%, enough for the small photos exam and job forms ask for. If the form gives dimensions, type that width: fewer pixels leave more of the 15 KB for quality.
At 15 KB, the tool tries the highest JPG quality first and only makes the photo smaller in pixels if it has to. How the image resizer works.

Tips for a clear, small photo
- Signatures: dark ink on white paper, cropped close, in Black and white.

- Range like 10 to 15 KB? Choose 15 KB; the result lands near the top, above the minimum.
