One desktop app for every exam photo and signature
Form season means the same two files over and over: a photo and a signature, each capped at a few KB, each with its own pixel size. Online tools make you upload those files one at a time to a server you don't control — not ideal when it's your face and your signature. Image Resizer PC does it all on your machine instead: no upload, no account, no watermark, no ads.
Because it lives on your PC, you keep it. Next exam, next form, next family member's application — just drag the file in again. You can also drop a whole folder of photos at once; there's no file-count limit.
Verified photo and signature size caps by exam
Here are the current photo and signature limits for the big national exams. Type the KB figure into the target box and set the pixels, and the app finds the best quality that fits. Each exam has its own detailed page with step-by-step help.
- SSC (CGL, CHSL, MTS, GD): photo 20–50 KB, signature 10–20 KB, about 200×230 px (3.5×4.5 cm), JPG — see the SSC photo & signature resizer page.
- IBPS (PO, Clerk, RRB, SO): photo 20–50 KB at 200×230 px, signature 10–20 KB at 140×60 px, JPG — see the IBPS page.
- UPSC (CSE): photo 20–200 KB, signature 20–100 KB, JPG.
- RRB NTPC: photo 5–200 KB, signature max 30 KB at 140×60 px, JPG.
- GATE: photo 5–200 KB, signature 4–30 KB, JPG.
- TNEA: photo 20–50 KB, signature 20–50 KB, JPG / JPEG / PNG.

How to keep a small photo or signature sharp
The smaller the KB target, the more the app has to compress — at a tiny 10–20 KB signature some softness is simply unavoidable, and that's normal. A few habits keep things as crisp as possible:
- Start from a clear, well-lit original — you can't add detail back later.
- Match the pixel size to what the portal wants (e.g. 200×230). Don't shrink pixels far below that, or text and edges go fuzzy.
- For signatures, scan or photograph on plain white paper, then crop tight before resizing.
- Let the preview show you the result and its KB weight before you save — if it looks rough, nudge the pixels up a little and try again.
Pixels, centimetres and the exact KB target
Portals describe size in three different ways and this app speaks all of them. Give it pixels (like 200×230) when the form lists pixels. Give it centimetres plus DPI (like 3.5×4.5 cm at 300 DPI) and it works out the right pixel dimensions for you. And separately, type the file weight in KB so the saved file lands at or under the cap.
You can keep the aspect ratio, or center-crop to an exact box when a form demands precise dimensions. Output as JPG for almost every exam, since that's what the portals accept.
