How to Resize a Photo to 20 KB for Online Forms (SSC, UPSC, PAN)
Updated August 15, 2026
Government and exam portals in India are strict about photo uploads: "Photo must be 20 KB to 50 KB, 200×230 pixels. Signature must be 10 KB to 20 KB, 140×60 pixels." Upload something even slightly off and the form rejects it. Here's how to hit those numbers exactly, in under a minute, without installing anything.
The 3 things forms actually check
- File size in KB — e.g. between 20 KB and 50 KB
- Dimensions in pixels — e.g. 200×230 px for photos
- Format — almost always JPG (sometimes JPEG is written, it's the same thing)
You must satisfy all three at once — that's why simply "saving again" from your phone gallery usually fails.
Step-by-step: resize a photo to 20 KB
- Open the free Image Resizer — it runs in your browser, and your photo is never uploaded to any server.
- Drop your photo into the box.
- Enter the required dimensions — for most exam forms that's 200 width × 230 height (uncheck "Lock aspect ratio" if needed, or use the "Form photo 200×230" preset).
- Set format to JPG.
- In the "Target size (KB)" field, type your limit — e.g. 20. The tool automatically finds the best quality that fits under 20 KB.
- Click Resize Image, check the preview, and Download.
Common form requirements cheat-sheet
| Document | Typical photo spec | Typical signature spec |
|---|---|---|
| SSC (CGL, CHSL, MTS) | 20–50 KB, JPG | 10–20 KB, JPG |
| UPSC | 20–300 KB, JPG | 20–300 KB, JPG |
| IBPS / SBI bank exams | 20–50 KB, 200×230 px | 10–20 KB, 140×60 px |
| PAN card (NSDL/UTI) | Max 20 KB, 213×213 px | Max 10 KB |
| Passport (India) | 10–1000 KB, 35×45 mm ratio | — |
Always confirm the exact numbers in your form's instructions — portals update them from time to time.
Photo too blurry after resizing?
- Start from the original camera photo, not a WhatsApp forward (WhatsApp already compresses images heavily).
- Resize the dimensions first, then let the target-KB mode handle quality — a 200×230 image looks sharp even at 20 KB.
- For passport-style framing (head centered, plain background), crop with the Passport Photo Maker first, then resize.
Is it safe to use an online tool for ID photos?
It depends on the tool. Most photo-resize websites upload your image to their servers. The tools on this site work differently — all processing happens inside your own browser, so your photo and signature never leave your device. You can even load the page, turn off your internet, and it still works.
