Signature Resize – Resize Signature for Online Forms

Resize Your Signature for Any Online Form

Every online application — recruitment exams, bank jobs, scholarships, university admissions, passport and PAN — asks you to upload a scanned signature in a strict format. A typical instruction says the signature must be 140×60 pixels and between 10 KB and 20 KB, in JPG format. A phone photo of a signature is usually several megabytes, has a grey or yellow background, shadows and a lot of empty space around the signature. As a result the portal shows errors like "invalid file size" or "image dimensions not correct". The free Signature Resize tool by Online Wala fixes this in seconds, directly on your mobile phone.

Features of the Signature Resize Tool

• Presets for common forms: SSC and most forms 140×60 px (10–20 KB), IBPS/bank 256×64 px (up to 12 KB), MPSC 300×80 px, and 3.5×1.5 cm.
• Custom size: type any width, height, minimum and maximum KB mentioned in your notification.
• White background: removes the grey or yellow paper colour and light shadows.
• Darker, clearer ink: faint pen strokes become sharp. You can also force the ink to pure black or blue.
• Auto crop: empty space around the signature is trimmed so the signature looks large and readable even in a small box.
• Exact KB control: the tool automatically adjusts JPG quality to land inside your KB range.
• Private: nothing is uploaded; everything happens in your browser.

How to Resize a Signature (Step by Step)

1. Sign on a clean, unruled white paper with a black or blue ball pen. A slightly thick pen gives the best result.
2. Take a straight photo in daylight without flash and without your shadow on the paper.
3. Open this tool and tap Choose signature photo.
4. Select the preset that matches your form, or enter the exact size from the advertisement.
5. Check the preview. If small dots remain in the background, reduce the ink detection slider; if parts of the signature disappear, increase it.
6. Tap Download signature (JPG). The final pixel size and KB are shown below the button. Upload that file to your form.

Common Signature Sizes in Indian Exams

Requirements change from one notification to another, so always read the official instructions. As a general guide, SSC and many central exams ask for about 4.0×2.0 cm or 140×60 px at 10–20 KB; banking exams often ask for 140×60 px at 10–20 KB or similar; railway and state commissions publish their own limits. When a form specifies centimetres, remember that at 300 DPI one centimetre is about 118 pixels, so 3.5×1.5 cm is roughly 413×177 px. Use the Custom option for such cases.

Tips for a Clean Signature Scan

Never sign on lined notebook paper, because the lines remain visible. Do not use pencil or gel pens that smudge. Keep the phone parallel to the paper so the signature is not tilted. Some forms specifically want black ink; choose "Black" in the ink colour option. If the portal also wants your photo and signature in one image, use our Photo + Signature Joiner. For a passport size photo use the Passport Photo Maker, and to compress any other image use Image Resize in KB.

Useful for CSC and Cyber Café Operators

If you fill online forms for customers every day, this tool saves a lot of time. Take the customer's signature on paper, click a photo, choose the preset and download — the whole job takes under a minute and needs no computer software.

Frequently Asked Questions

How do I make my signature 10 KB to 20 KB?

Enter 10 as Min KB and 20 as Max KB (already filled in the SSC preset). The tool automatically fits the file into that range.

Why is my signature background not fully white?

The photo probably has a shadow or poor light. Reduce the ink detection slider slightly or retake the photo in daylight.

Can I change blue ink to black?

Yes. Select "Black" under ink colour and the signature strokes become pure black.

Is my signature safe?

Yes. The image is processed only inside your browser and is never sent to our server.

Does it work on mobile?

Yes, it is designed for mobile phones and also works on laptops and desktops.

Signature Rules to Remember

Sign exactly the way you sign on official documents, because the same signature may be verified at the exam centre or during document verification. Do not sign in capital letters if the instructions forbid it, and never upload a typed or printed name instead of a signature.

Conclusion
