How to resize an image to 300 KB
- Choose your photo. JPG, PNG and WebP all work, including photos straight from your phone.
- Check the size. 300 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 300 KB
Tested on October 30, 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 | 299 KB | 1855×2379 | 62% |
| Landscape | 298 KB | 1843×1229 | 58% |
| Signature | Already under | 1800×700 | Kept |
| Document | 298 KB | 2121×3000 | 73% |
At 300 KB the face photo kept 1855 × 2379 px at quality 62%, more pixels than most forms ask for. If the form gives dimensions, type that width: fewer pixels leave more of the 300 KB for quality.
At 300 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 300 KB
| Upload | Size | Dimensions |
|---|---|---|
| Some UPSC notices: photo and signature | 20 to 300 KB | others cap them at 200 and 100 KB |
| Application portals: document photo (ID card, certificate) | often up to 300 KB | as stated on the form |
| Website and profile uploads | often up to 300 KB | about 1200 to 1800 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
- 300 KB is roomy: a phone photo usually keeps most of its pixels with no visible change.
- Document photos stay readable at full phone width; crop to the page first.
- A range like 20 to 300 KB? Choose 300 KB for the best quality, or type the width the form asks for.
