Photo & Signature Resize for Online Forms

SSC, UPSC, banking, railway and other forms ask for a photo and signature JPEG within strict KB and pixel limits, and each exam sets its own numbers. This guide shows how to resize both correctly with the free Photo / Sign KB tool and how to verify the files before uploading.

There is no single "correct" KB size. Every exam notice sets its own range, format and dimensions, and cycles change. Check your own exam's current notice or our per-exam guides below, then enter those verified numbers yourself.

Step by step: resize a photo or signature

Check your exam's exact requirement: file format (usually JPG/JPEG), KB range, pixel dimensions, and any background or ink rules. Our exam photo guides list verified numbers with sources for major exams.
For a signature, sign on clean white paper as the notice requires (many demand black ink and running handwriting, not block letters), then scan or photograph it in good light.
Crop extra space first with the Photo Editor so the subject fills the frame without cutting anything off.
Open Photo / Sign KB and enter the verified KB range and dimensions yourself. Do not trust a preset from another exam or an older cycle.
Download the JPEG and check three things separately: actual file bytes/KB, pixel dimensions, and that the image looks clear in a separate viewer.

Checks that reject uploads

Right KB but wrong dimensions, or the other way round. Both are checked separately by most portals.
A renamed file. Changing photo.png to photo.jpg changes the name, not the format; portals reject it.
Over-compression. A signature squeezed far below its range can become unreadable and fail manual review even if the portal accepts the file.
Old-cycle numbers. Limits from a previous year's notice or a different exam do not transfer.

Some cycles require a live photo captured inside the application module instead of an uploaded JPEG. The guide for your exam says which applies; a resized file cannot replace a live capture.

Frequently asked questions

Will a resized photo or signature definitely be accepted?

No tool can guarantee acceptance. Portals check KB, pixel dimensions, format and image quality separately, and some cycles need a live capture. Verify each requirement and the portal preview.

Are my photo and signature uploaded anywhere?

No. Resizing runs in your browser on your device. Your files are not sent to a server.

My file is under the KB limit but still rejected. Why?

Check the pixel dimensions, the actual format (not just the extension), background and ink rules, and whether your cycle requires a live photo. Each is a separate check.

Should I compress as much as possible?

No. Stay inside the notice's stated KB range, not below it. A file squeezed too far becomes unclear and can fail review even when the portal accepts the upload.
