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.

About the SSC Signature Resizer
SSC (Staff Selection Commission) exams — CGL, GD Constable, CHSL, and others — are among the most heavily applied-to competitive exams in India, with registration windows that see enormous volumes of applicants submitting within days of each other. Every application requires a scanned or photographed signature that meets a specific, usually quite small, file size and pixel dimension requirement. Getting this wrong is one of the most common, entirely avoidable reasons an SSC application gets flagged during the automated registration check — often with no opportunity to fix and resubmit before the window closes.
This tool resizes and compresses your signature to the correct SSC specification automatically, so you can be confident it meets the requirement before you submit, rather than hoping it does.
SSC Signature Requirements
Format: JPEG / JPG Only
SSC application portals accept only JPEG/JPG format for signatures. If you have a PNG or other format file, this tool converts it automatically.
File Size: 20 KB to 50 KB
Your signature must be between 20KB and 50KB. Files smaller than 20KB may appear blurry, while files larger than 50KB will be rejected by the portal.
Dimensions: 3.5cm × 1.5cm (140 × 60 Pixels)
The SSC signature must be 3.5cm wide × 1.5cm tall, which translates to 140 × 60 pixels at standard resolution. This tool resizes your signature to these exact dimensions automatically.
Step-by-Step: Resizing Your Signature for SSC
- 1Sign on plain white paper. Use a dark pen for good contrast, and keep the signature reasonably sized relative to the page.
- 2Scan or photograph it clearly. Even lighting, no shadows, and a straight-on angle give the cleanest source image.
- 3Upload it here. Choose whether you prefer to see dimensions in centimeters (3.5×1.5cm) or pixels (140×60px) — both produce the same result.
- 4Automatic resizing and compression. The tool applies the correct dimensions and compresses to your target KB size in one step.
- 5Download and submit. Your signature file is ready, correctly sized for SSC's application portal.
Why Signature Compression Is Trickier Than Photo Compression
A signature might seem simpler to compress than a full photograph, but it actually presents its own challenge: signatures rely entirely on thin, high-contrast lines against a plain background, and aggressive compression can blur or break up those fine strokes in a way that's more visually obvious than similar compression applied to a photo, where detail loss is less noticeable. Our tool accounts for this by preserving edge contrast — the sharp transition between ink and paper — even as it reduces overall file size, since that contrast is what keeps a signature legible after heavy compression.
This runs through the same real JPEG compression engine used across all SnapToolHub tools, operating entirely inside your browser via WebAssembly — no server involved, no upload required, nothing to wait on beyond the instant it takes your device to process the file locally.
Frequently Asked Questions
What size does my SSC signature need to be?
SSC requires signatures in JPEG format, between 20KB and 50KB, with dimensions of 3.5cm × 1.5cm (140 × 60 pixels). Always verify against your specific exam's current notification.
What's the difference between CM and PX presets?
Both presets produce the exact same output — 140 × 60 pixels. The CM preset shows dimensions as 3.5×1.5cm, while the PX preset shows them as 140×60px. Choose whichever unit you're more comfortable with.
Can I use this tool for SSC CGL, GD, and CHSL?
Yes — the signature requirements (3.5cm × 1.5cm, 20-50KB, JPEG) are generally consistent across SSC exam types. Upload your signature and this tool handles the rest.
My signature looks unclear after resizing — what should I try?
Start with a higher-contrast, larger original — dark ink on plain white paper, evenly lit, with no shadows — which compresses far more cleanly than a low-contrast or cluttered scan.
Is my signature ever uploaded or stored anywhere during this process?
No — it's processed entirely inside your browser, on your own device, and never transmitted anywhere at any point.
What if my SSC application keeps getting rejected even after resizing?
Double-check that you're using JPG format, the file size is between 20KB and 50KB, and the dimensions match 3.5cm × 1.5cm (140 × 60 pixels). Also ensure the full signature is visible and not cropped at the edges.
