How these tools keep your application from being rejected

Indian exam portals validate uploads automatically: a signature that is 21 KB when the limit is 20 KB, or a photo at the wrong aspect ratio, is rejected before a human ever sees it. Our resizers work in three steps — first the image is decoded and its orientation corrected, then it is fitted to the exact pixel dimensions your exam requires, and finally the JPEG quality is binary-searched until the file lands inside the official KB window. The result is the largest, sharpest file the portal will accept.

For signatures, faint pencil-grey scans are the top rejection cause after file size. The ink-boost slider increases contrast, the whitening option flattens off-white paper to pure white, and grayscale removes colour casts from phone photos — producing the clean black-on-white signature every notification demands.

Everything runs locally on your device. Unlike upload-based resizers, your photograph and signature never travel to a server, which matters for documents tied to your identity.

Frequently asked questions

Why do exam portals reject my photo or signature upload?

The most common reasons are file size outside the allowed KB range, wrong pixel dimensions, wrong format (only JPG/JPEG is accepted by most portals), a non-white background, or a blurred scan. Our tools fix the size, dimensions and format automatically.

Are my photos uploaded to a server?

No. Every tool on this page runs 100% in your browser using your device’s own processor. Your photo and signature never leave your device.

How do I resize a signature to 10–20 KB for SSC or IBPS?

Open the Signature Resizer, pick your exam, and drop in your scanned signature. The tool resizes it to the exact pixel dimensions and compresses it into the required KB range in one step, with ink-boost and background-whitening options for faint scans.

Are these specifications up to date?

Yes — every KB range and pixel dimension was re-verified against current official notifications and portal guidelines on 2026-06-11. The verification date is shown on every tool. Always cross-check your specific cycle’s notification before final submission.

Can I prepare the IBPS thumb impression and handwritten declaration here?

Yes. The Signature Resizer includes presets for the IBPS left thumb impression (240 × 240 px, 20–50 KB) and handwritten declaration (50–100 KB) in addition to the photo and signature.
