How to Resize Signature to 140x60 Pixels and Under 20KB for Exam Forms

Government recruitment portals (SSC CGL, IBPS PO, GATE, RRB, and UPSC) strictly reject signature uploads that do not match exact pixel dimensions like 140x60 px or exceed 10KB-20KB. With iEditPDF's client-side resizer, you can lock aspect ratios or dial in 140x60 px instantly.

Pro Tip: Avoid shadows over the signature for the cleanest digital background.

Enter Exact Dimensions: 140 Width x 60 Height

In the dimensions panel, select 'Pixels (px)'. Uncheck 'Lock Aspect Ratio' if your portal strictly checks 140x60, and enter 140 width and 60 height.

Pro Tip: If the signature looks slightly stretched, crop it tightly first using our Crop Tool.

Verify File Size Under 20KB

Check the real-time file size estimator at the bottom. The output typically compresses to 6KB - 14KB, which falls safely inside portal thresholds.

Pro Tip: Export as JPG or PNG depending on what your application guidelines specify.

Download & Upload to Your Exam Portal

Click 'Save Resized Image' to download the ready-to-upload signature directly to your smartphone or computer disk.

Pro Tip: You can test the file immediately on your SSC or IBPS upload preview screen without rejection.

Frequently Asked Questions

Why do exam portals require 140x60 pixels for signatures?

Recruitment software uses automated template matching to print signatures onto admit cards and attendance sheets in designated rectangular boxes.

How can I reduce my signature file size below 20KB if it is still 50KB?

If your signature file exceeds 20KB after resizing, open it in our Compress Image tool and choose the '20 KB' chip to optimize it in 1 click.

Is it safe to upload my official signature here?

Yes. iEditPDF runs entirely inside your web browser via client-side Canvas and WebAssembly. Your signature is never uploaded to any server or database.
