Online Signature Maker for SSC, UPSC, IBPS & Railway Forms (10KB / 20KB)

Every month millions of Indians search "online signature maker", "signature 10KB for form", and "how to upload signature in SSC form". If your scan is too large or you do not have a scanner, drawing a signature on your phone works — when you export the correct size and format.

Quick answer: Draw a black signature on white in Signature Maker and download the exact 10KB or 20KB JPG preset your SSC, IBPS, or railway notification lists.

Why signature upload fails (most common reasons)

• File too big — portal wants 10KB–20KB, your scan is 500KB+
• Full page scanned — upload only the signature area, not A4 sheet
• Wrong format — JPG required, not PNG or PDF
• Blur or shadow — phone photo at an angle

Signature size by portal (check official notice)

Method 1 — Draw signature online (fastest)

1. Open PhotoBandhu Signature Maker.
2. Draw with finger or mouse on white canvas — use black pen setting.
3. Click Download 10KB JPG or 20KB JPG as per your form.
4. Upload to the portal.

Processing stays in your browser — signature is not uploaded to our servers.

Method 2 — Sign on paper, then compress

1. Sign on plain white paper with black pen.
2. Take a straight photo (no shadow).
3. Crop tightly around signature only.
4. Compress to KB — target 10KB or 20KB.

Pre-upload checklist (60 seconds)

1. Re-read notification: signature KB min/max and JPG-only rule.
2. Zoom preview — no grey paper border, no second person’s writing in frame.
3. File name simple: signature.jpg — some portals dislike spaces or Hindi characters.
4. Upload photo and signature as separate fields — do not swap them.
5. Save a copy offline before session timeout on busy registration days.

RRB vs SSC signature quirks

Railway (RRB): Sometimes allows slightly higher KB (up to ~50KB). Still export JPG; PNG signatures blow past limits.

SSC / UPSC: Tight 10–20KB window — Signature Maker presets beat manual slider apps.

IBPS: Often same as SSC; if both photo and signature fail, fix photo pixels first — error messages can be misleading.

Common mistakes

• Scanning entire A4 page instead of cropping ink area only.
• Blue pen on coloured paper — portals expect black on white.
• Using someone else’s signature sample from YouTube — legal and verification risk.
• Re-compressing the same JPG five times to “try” different sizes — export fresh from Signature Maker.
