Total Privacy — We Don't Save It Anywhere (0 Uploads Policy)
Your signature is never uploaded in the first place. The entire compression process — decoding, analyzing, re-encoding, checking the file size — happens locally, inside your own browser, on your own device. There's no upload step to intercept, no server log to worry about, no brief window where your file exists somewhere outside your control. We don't delete your file afterward because we never received it to begin with. If you want to verify this yourself, turn off your WiFi right after this page finishes loading — the tool will still work perfectly, because it never needed an internet connection.

Why UPSC Signature Compliance Matters
UPSC runs some of India's most competitive exams — Civil Services, IAS, NDA, CDS, and more — and their application portal is strict about signature specifications. Unlike most other exam portals, UPSC requires your scanned signature file to contain exactly three signatures arranged vertically on a single sheet. The system automatically checks file size, and anything outside 20KB to 100KB gets rejected immediately.
Most applicants don't realize their signature file is the wrong size or format until the portal throws an error during submission. This UPSC signature compressor handles the file size part instantly — just upload, pick your target KB, and download a file that fits the requirement.
What UPSC Expects in Your Signature
Three Signatures, Vertically Arranged
You must sign your own signature three times, one below the other, on a plain white paper using black ink. Leave adequate space between each signature so they are clearly separated in the scanned image.
Format: JPEG / JPG Only
UPSC's portal only accepts JPEG/JPG files for signature uploads. If you have a PNG or other format, this tool converts it to JPG automatically during compression.
File Size: 20 KB to 100 KB
Your signature file must fall between 20KB and 100KB. The portal won't accept anything smaller or larger. Set your target size in this tool and it compresses precisely to that range.
Dimensions: 350 to 500 Pixels
UPSC specifies that the signature image dimensions must be between 350 and 500 pixels. This tool lets you set the exact pixel width and height, so you can match this requirement precisely.
Clear, Sharp, and Well-Lit
The scanned image must be clear, sharp, and well-lit — not blurred or dark. The signatures should be properly oriented (not rotated or upside down) on plain white paper with no lines or colours.

How to Compress Your UPSC Signature
- 1Prepare your signature sheet. Sign three times vertically on plain white paper using black ink. Leave enough space between signatures so they don't overlap when scanned.
- 2Scan clearly. Use a flatbed scanner or a scanning app on your phone. Make sure the image is sharp, well-lit, and properly oriented — not rotated or upside down.
- 3Set dimensions and file size. UPSC requires 350–500 pixels and 20–100KB. Set your target dimensions and pick 50KB as a safe middle ground.
- 4Upload and download. The tool compresses your signature to the target KB size while preserving clarity. Download the result — it's ready for UPSC's portal.
