Frequently Asked Questions
How can I resize an image to exactly 20KB?
Trying to do this manually is hard. Our tool uses a binary loop to check the output size after every compression change, ensuring we get as close to 20KB as possible without going over.
Will my image look blurry at 20KB?
At 20KB, some data is lost, but our algorithm prioritizes edges and contrast. For signatures, the lines remain dark and sharp, which is what portal officials look for.
Is this tool free for multiple images?
Yes, Utilifyx is 100% free and does not limit the number of files you can process.
Can I resize PNG to 20KB?
Yes, but we automatically convert the output to JPG because JPG is much more efficient at small file sizes and is the standard for govt forms.
Does it work on Android phones?
Yes, just open Utilifyx on Chrome or Safari on your phone, and it works perfectly.
Why 20KB is the Magic Number for Indian Portals
Most Indian government websites, from the Staff Selection Commission (SSC) to the Union Public Service Commission (UPSC), have a standard requirement for signatures: they must be between 10KB and 20KB. This is because these signatures are often printed on small areas of admit cards and certificates.
The Challenge of Manual Compression
If you use standard photo editors, you might get a 22KB or a 18KB file that looks like a smudge. Hitting exactly under 20KB while maintaining 'Recognizable' quality is a technical feat. Our engine focuses on Luminance Preservation, ensuring that the black ink of your signature stands out against the white background, even at high compression ratios.
Use in SSC Application
For SSC CGL and CHSL, the signature specifications are usually 4.0 cm width x 2.0 cm height, and a size of 10 to 20 KB. If you select our 20KB preset, we optimize the encoding to fit this exact requirement.
