How to resize an image to 20 KB
- Choose your photo. JPG, PNG and WebP all work, including photos straight from your phone.
- Check the size. 20 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 20 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 | 20 KB | 486×624 | 57% |
| Landscape | 20 KB | 483×322 | 55% |
| Signature | 20 KB | 1800×700 | 45% |
| Document | 20 KB | 356×503 | 57% |
At 20 KB the face photo kept 486 × 624 px at quality 57%, 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 20 KB for quality.
At 20 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 20 KB
| Upload | Size | Dimensions |
|---|---|---|
| Bank exams (IBPS): signature | 10 to 20 KB | 140 × 60 px |
| Many exam and job portals: signature | up to 20 KB | as stated in the notice |
| Small passport-style photos on older portals | 10 to 20 KB | about 200 × 230 px |
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 first. A passport-style photo of your face and shoulders reaches 20 KB at a much better quality than a whole-room photo.
- Set a width of 200 to 350 pixels if the form gives photo dimensions: smaller pixels leave more KB for quality.
- Signatures: sign in dark ink on white paper and photograph it in daylight; tick Black and white.
Questions
How do I resize an image to 20 KB?
Choose your photo on this page, keep 20 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.
My form says 10 to 20 KB. Will the photo come out too small?
Not usually. The tool keeps the highest quality that fits, so the result lands close to 20 KB, well above the 10 KB minimum. If a form rejects it as too small, choose a bigger width or turn off Black and white.
