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 Signature Compression Matters
Almost every Indian competitive exam — SSC, RRB, IBPS, state PSCs — requires a scanned signature upload as part of the online application. The portal enforces strict file size and dimension limits, and getting it wrong is one of the most common, entirely avoidable reasons an application gets flagged during the automated registration check. Unlike a photo, a signature relies on thin, high-contrast lines against a plain background, and aggressive compression can blur or break those fine strokes in a way that's more visually obvious than similar compression on a photograph.
This tool resizes and compresses your signature to the correct specification automatically — so you can be confident it meets the requirement before you submit, rather than hoping it does.
What Most Exam Portals Expect
Dimensions: 140 × 60 Pixels (3.5cm × 1.5cm)
Most SSC, RRB, and banking exam portals require signatures at 140×60 pixels, which translates to 3.5cm × 1.5cm at standard resolution. Choose between centimeters or pixels below — both produce the same result.
File Size: 10 KB to 20 KB
Most portals require signatures between 10KB and 20KB. Some allow up to 50KB. Set your target size in this tool and it compresses precisely to that range.
Format: JPEG / JPG Only
Most exam portals only accept JPEG/JPG files. If you have a PNG or other format, this tool converts it to JPG automatically during compression.
Black Ink on White Paper
Sign using black or dark blue ink on plain white paper. The scan should be clear and sharp — avoid using coloured paper or signing on lined paper.
Dos and Don'ts for Your Signature
Do
- ✓Use black or dark blue ink on plain white paper
- ✓Keep your signature clear and legible
- ✓Crop tightly around the signature before compressing
- ✓Ensure even lighting with no shadows on the scan
- ✓Compress to 10–20KB range before uploading
Don't
- ✗Sign on lined, coloured, or patterned paper
- ✗Use a pen that produces faint or light strokes
- ✗Submit a blurry, dark, or poorly lit scan
- ✗Use block letters or capital letters instead of a signature
- ✗Upload a file larger than 20KB or in PNG format
How to Resize Your Signature
- 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 for your exam portal — correct dimensions, correct size, correct format.
Frequently Asked Questions
What is the standard signature size for exam forms?
Most Indian exam portals require signatures at 140×60 pixels (3.5cm × 1.5cm), with file sizes between 10KB and 20KB in JPG format. Some portals like SSC allow up to 50KB.
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.
How do I get a clear signature scan from my phone?
Sign with dark blue or black ink on plain white paper, take a well-lit photo from directly above (no shadows), crop tight to the signature, and compress using this tool.
Can I use this for SSC, RRB, and banking exams?
Yes — the 140×60 pixel dimension is the most common signature requirement across SSC, RRB, IBPS, SBI, and other banking exam portals.
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.
Will my application be rejected for wrong signature size?
Yes — the portal automatically validates file size and dimensions. Files outside the required range will be rejected at the upload step. This tool compresses to the exact target range.
Is my signature uploaded to any server?
No. The entire compression process happens inside your browser on your own device. Your signature is never transmitted, stored, or processed on any external server.
