How to resize an image to 30 KB
- Choose your photo. JPG, PNG and WebP all work, including photos straight from your phone.
- Check the size. 30 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 30 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 | 29 KB | 608×780 | 56% |
| Landscape | 30 KB | 604×403 | 54% |
| Signature | 29 KB | 1800×700 | 77% |
| Document | 30 KB | 445×629 | 58% |
At 30 KB the face photo kept 608 × 780 px at quality 56%, more pixels than most forms ask for. If the form gives dimensions, type that width: fewer pixels leave more of the 30 KB for quality.
At 30 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.
Forms that ask for 30 KB
| Upload | Size | Dimensions |
|---|---|---|
| Exam and job portals: passport photo | up to 30 KB | as stated in the notice |
| Exam and job portals: signature with a larger limit | up to 30 KB | as stated in the notice |
Typical limits: your form's own notice has the final word. See the official limits for SSC, IBPS, SBI, NEET, JEE and GATE.
Tips for a clear, small photo
- Crop to face and shoulders before resizing: the KB go to your face, not the wall.
- A plain light background compresses better and looks cleaner on forms.
- Width 300 to 400 px is plenty for a passport photo at 30 KB.
