Signature 140 by 60 pixels Trim empty white margins
Identity Card Standard ID card scan Ensure text remains fully legible

Tips for Best Results

  • Crop away unnecessary background space before you start the compression process.
  • Ensure your original photo has good lighting and clear contrast.
  • Save your final output in standard JPG format for maximum portal compatibility.
  • Check the official application guidelines for exact dimension rules.
  • Test your upload on a desktop computer if your mobile browser fails.

Understanding Portal File Restrictions

Many government websites and university admission portals enforce strict limits because they handle millions of submissions daily. Large files overload their servers and slow down the entire registration system for every other applicant.

  • Server storage limits prevent database crashes during peak application seasons.
  • Standardized dimensions ensure uniform display on verification dashboards.
  • Local processing guarantees your sensitive documents never touch a third-party cloud.
