Why Signature Uploads Get Rejected & How to Prevent It
Incorrect ink colors or bad lighting account for many online form signature rejections. Keep these rules in mind:
✓ Best Practices
- Sign using a fresh black or dark blue gel/ballpoint pen.
- Sign on an unruled, completely plain white sheet of paper.
- Take the photo under direct light to avoid hand shadows.
- Crop closely around the signature edges before uploading.
✕ Direct Rejection Causes
- Never sign in CAPITAL letters (MUST be running handwriting).
- Do not sign on lined, checkered, or dirty paper.
- Do not use red, green, or faint pencil strokes.
- Avoid blurry photos or shadows casting across the paper.
Frequently Asked Questions (FAQs)
My signature looks too faint or light — how do I fix it?
This usually happens when a signature is photographed under weak indoor lighting or written with a worn-out pen. FormMate automatically boosts the contrast between the ink and the paper, darkening faint strokes so the signature reads clearly instead of looking washed out.
How can I compress a signature under 20KB without blurring the lines?
FormMate darkens the ink lines and whitens the paper background before compressing, so the file size drops toward the 10KB–20KB range while the signature stroke stays crisp and readable rather than blurring out. This is what enhances signature image quality even after the file size is reduced.
What are the pixel dimensions for signature in government forms?
The standard signature dimension for SSC, IBPS, and most central government recruitment forms is 140 pixels wide by 60 pixels tall (4.0 cm × 2.0 cm). Some portals use different specs — check the table above for your specific exam.
Can I fix a signature photo taken with a mobile camera under room light?
Yes. Mobile photos taken under indoor lighting often come out yellow or gray. FormMate boosts contrast between the ink and paper to turn that background bright white and make the signature stand out clearly.
Is signing in ALL CAPS allowed in SSC or Banking forms?
No. Official exam portals like SSC and IBPS explicitly reject signatures written in ALL CAPITAL LETTERS. Always sign in your natural running handwriting.
Is my signature image safe on FormMate?
Yes. Your signature is processed right there on your own phone or computer — it's never uploaded, transmitted, or saved to any external server.
