Why Compress Images to 20KB?
If you are applying for government jobs, college admissions, or national exams in India (such as SSC, UPSC, IBPS, or NTA portals), you know the strict document rules. Almost every online application form requires your digital signature or passport-size photograph to be under 20KB in size. Uploading a file even 1KB larger results in an error.
Our free 20KB image compressor is designed specifically for students and applicants. It uses smart, in-browser compression to shrink the file size of your JPEGs and PNGs without blurring the important details of your face or signature. Because the compression happens entirely on your device, your highly sensitive personal documents are never uploaded to our servers, guaranteeing 100% data privacy.
