Set the final dimensions (e.g., 3.5cm x 4.5cm) and file size (e.g., 50KB). Click download to save the merged image.

Why Merge a Photo and Signature Together?

When applying for competitive exams like SSC (Staff Selection Commission), Railway Recruitment Board (RRB), UPSC, or State Police, many application portals require candidates to upload a single JPEG file containing both their photograph and their signature appended directly below it.

Creating this manually using software like MS Paint or Photoshop is frustrating. You have to carefully align both images, remove the grey/dark background from the signature photo, and ensure the final file doesn't exceed the strict 50KB or 100KB size limit. Smart CSC Tool automates this entire headache in just four simple clicks.

Advanced Features: Background Removal and Ink Color Change

Our tool is packed with smart algorithms built specifically for form-filling:

  • Auto Background Removal: Even if you click a photo of your signature on a slightly dark or yellowish paper, our tool detects the ink and makes the background completely transparent automatically.
  • Change Blue Pen to Black: Many exams specifically demand signatures done in Black Ink. If you signed using a blue pen, simply use our Color Picker in Step 3 to change the ink color to Pitch Black instantly.
  • Precise DPI & Size: In the final step, you can encode exactly 200 DPI or 300 DPI into the photo and compress it below 50KB, ensuring 100% acceptance by the portal.

100% Privacy Guaranteed: Both your photograph and your sensitive signature are processed locally inside your web browser. We do not store or upload your signature to any external servers.

Frequently Asked Questions

How do I change my blue signature to black?
In Step 3, after you upload your signature image, look for the "Ink Color" option. Click on the color circle and select black (or enter #000000). The tool will instantly convert your blue ink strokes into sharp black lines.
Will the dark paper background of my signature show up on the photo?
No. Our built-in script automatically detects the brightness of the uploaded signature photo. It turns the light/paper areas completely transparent and only keeps the dark pen strokes, making it look like you signed directly on the photo digitally.
Can I reduce the merged photo size to under 50KB?
Yes! In the final step (Step 4), simply type "50" in the Compression Size box before clicking Download. The tool will merge the photo and signature, and then compress the final file to exactly fit under 50KB without losing readability.
