How to resize an image to 10 KB
- Choose your photo. JPG, PNG and WebP all work, including photos straight from your phone.
- Check the size. 10 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 10 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 | 10 KB | 311×399 | 59% |
| Landscape | 10 KB | 387×258 | 38% |
| Signature | 10 KB | 922×358 | 64% |
| Document | 10 KB | 228×322 | 65% |
At 10 KB the face photo kept 311 × 399 px at quality 59%, 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 10 KB for quality.
At 10 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 10 KB
| Upload | Size | Dimensions |
|---|---|---|
| Staff Selection Commission (SSC) exams: signature | 10 to 20 KB | about 6.0 × 2.0 cm |
| Bank exams (IBPS): signature | 10 to 20 KB | 140 × 60 px |
| Older portals: signature or thumb impression | up to 10 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 tightly around the signature; every bit of empty paper costs KB.
- Black and white keeps a signature crisp at 10 KB.
- Type the width if the form gives one, for example 140 for 140 × 60 px.
Questions
How do I resize an image to 10 KB?
Choose your photo on this page, keep 10 KB selected and press Resize image. You get a JPG under that size, at the highest quality that fits, with no sign-up and no watermark.
How do I get a signature under 10 KB?
Sign in dark ink on plain white paper, photograph it in daylight, crop tightly around the signature, tick Black and white and choose 10 KB. A signature is mostly white space, so it stays sharp even this small.
