The tool cleans the paper to pure white, keeps the full signature inside the frame and sets the exact pixel size and DPI when a form needs it. For your photo, use compress image to 50 KB or the PAN card photo resize presets.

Signature specifications by form
| Form | Usually asked for |
|---|---|
| SSC (CGL, CHSL, MTS, GD) | JPG, 10–20 KB |
| IBPS / bank exams | JPG, 140×60 px, 10–20 KB |
| PAN online (NSDL / Protean) | JPG, 2×4.5 cm at 200 DPI, up to 10 KB |
These figures come from recent notices and instructions; exam bodies revise them, so confirm them in the notification you are applying under.
How to photograph a signature that resizes well
- Use a thick black gel or ball pen. Thin, light strokes can fade when the file is made very small.
- Sign inside a box about 6–7 cm wide so the signature is wider than tall, like the frame most portals use.
- Shoot from directly above in daylight, without your phone's shadow on the paper.
- Crop close to the signature before or after choosing the file; the tool then adds even white margins.
SSC signature size: 4×2 cm or 6×2 cm?
You will find two sizes quoted for SSC signatures. Many resizer sites list 4.0 × 2.0 cm (about 140 × 60 px), while coverage of recent SSC CGL notices lists 6.0 × 2.0 cm. Both agree on a JPG between 10 and 20 KB. The size that counts is the one printed in the notice you are applying under, so open it before you resize.
Use the SSC · 6×2 cm preset when your notice says 6 × 2 cm, and the plain SSC · 10–20 KB preset when the notice only gives a file size. Both keep the whole signature on a white background.
Signature size in cm and pixels
Forms give sizes either in centimetres or in pixels. To convert, multiply centimetres by the DPI and divide by 2.54. The table shows the common signature sizes:
| Signature size | At 100 DPI | At 200 DPI |
|---|---|---|
| 4 × 2 cm | 157 × 79 px | 315 × 157 px |
| 6 × 2 cm (SSC CGL notices) | 236 × 79 px | 472 × 157 px |
| 4.5 × 2 cm (PAN, NSDL) | 177 × 79 px | 354 × 157 px |
| 140 × 60 px (IBPS) | about 3.6 × 1.5 cm at 100 DPI | |
Type the pixel numbers under Dimensions, DPI and background, or pick a preset that already has them.

Signature Resize FAQs
Why is my signature rejected even though it is under 20 KB?
Portals often check a minimum size and the pixel dimensions too. Use a preset with a minimum (10–20 KB) and, if the form lists pixels such as 140×60, type them in so the file matches exactly.
Can I use a scanned signature?
Yes. A scan works well; the "make paper background pure white" option removes the grey tint scanners often leave.
Will it crop my signature?
No. Signature presets fit the whole image inside the frame and fill the leftover space with white.
Do you keep a copy of my signature?
No copy exists outside your device. The resizing runs in your browser and nothing is uploaded.
How do I get the signature under 10 KB?
Choose the PAN (NSDL) preset or type 10 as the maximum. Crop close to the signature first; the smaller the empty area, the easier it is to stay under 10 KB without blurring the ink.
What is the standard signature size in pixels for exam forms?
Bank exams such as IBPS commonly ask for 140 × 60 pixels and 10–20 KB. SSC notices give the size in centimetres. Always use the numbers in your own notice.
Can I resize a signature in centimetres?
Yes. Convert centimetres to pixels (cm × DPI ÷ 2.54), or pick the SSC 6×2 cm or PAN 4.5×2 cm preset, which set the pixels and 200 DPI for you.
How do I remove the grey shadow from a phone photo of my signature?
Keep "Make paper background pure white" ticked. It turns the grey paper white and darkens the ink. Taking the photo in daylight without your phone's shadow helps too.
