Resize a photo to the exact size your form asks for
Online forms usually describe the photo in two ways at once: a pixel size like 200 x 230, and a file size range like 20 to 50 KB. Some forms use centimetres instead, for example 3.5 x 4.5 cm. This tool takes all of that as input and gives you one JPG that satisfies every rule.
Type the numbers exactly as they appear in your notification. If the form only gives a KB limit and no pixel size, turn on Keep original size and the tool will only reduce the KB.
Step by step
- Enter the width and height. Change the unit to cm, mm or inch if your form uses those.
- Enter the minimum and maximum KB. If there is no minimum, leave it at 0.
- Choose a photo from the gallery or take one with the camera.
- Drag the photo to place your face in the oval, and pinch or scroll to zoom.
- Press Create file, check the size shown, and download.
Common photo sizes
| Used by | Pixels | File size |
|---|---|---|
| IBPS, SBI, RBI bank exams | 200 x 230 | 20 to 50 KB |
| NEET, JEE Main, CUET (NTA) | Not fixed, passport style | 10 to 200 KB |
| UPSC (with name and date) | 350 to 1000 on each side | 20 to 300 KB |
| SSC and CTET | 3.5 x 4.5 cm | 20 to 50 KB (SSC), 10 to 100 KB (CTET) |
| PAN card (Protean) | 3.5 x 2.5 cm at 300 DPI | Up to 50 KB |
Each exam has its own page with all upload sizes. See the full exam list.
Converting centimetres to pixels
A centimetre has no fixed number of pixels. It depends on the DPI (dots per inch). Most forms that give sizes in cm expect around 200 to 300 DPI. One inch is 2.54 cm, so the pixel count is: centimetres divided by 2.54, multiplied by the DPI.
| Size in cm | At 200 DPI | At 300 DPI |
|---|---|---|
| 3.5 x 4.5 cm | 276 x 354 px | 413 x 531 px |
| 2.5 x 3.5 cm | 197 x 276 px | 295 x 413 px |
| 4 x 2 cm (signature) | 315 x 157 px | 472 x 236 px |
| 3.5 x 1.5 cm (signature) | 276 x 118 px | 413 x 177 px |
You don't need to calculate this yourself. Choose cm as the unit, type the DPI, and the tool shows the pixel size it will use.
Tips for a photo that gets accepted
- Stand facing a window during the day. Avoid tube light from above, which casts shadows under the eyes.
- Use a plain white or very light wall behind you.
- Look straight at the camera with a normal expression. Both ears should be visible.
- No cap, no dark glasses, no filters or beauty mode.
- Your face should fill about 60 to 70 percent of the photo height. The oval guide in the tool shows this.
- Use a recent photo. Many forms reject photos older than three to six months.
Why the KB comes out exactly in range
JPG files can be saved at different quality levels. Higher quality means more KB. The tool tries quality levels in a smart order and keeps the best one that stays under your maximum. When even the best quality is still below your minimum, which happens with small, clean photos, it adds empty padding inside the file. Image viewers and exam portals ignore that padding, so the photo looks the same but now meets the minimum.
Portals also differ in how they count KB. Some treat 1 KB as 1000 bytes, others as 1024 bytes. The tool keeps your file inside the range under both rules, so a file that shows 49.5 KB here won't be rejected as 50.7 KB elsewhere.
Frequently asked questions
Will my photo look stretched?
No. The tool always crops your photo to the right shape before resizing, so faces are never squeezed.
Can I resize a photo taken on an iPhone?
Yes. Choose the photo as usual. If your browser can't open it, set the iPhone camera to "Most Compatible" in Settings, Camera, Formats, so new photos are saved as JPG.
The form says 20 KB to 50 KB. What should I enter?
Enter 20 as Min KB and 50 as Max KB. The result will land safely between the two.
Can I make a white background here?
The website keeps your original background. The FormKit Android app can replace it with white using on-device AI.
