Frequently Asked Questions
Can I compress a 5MB photo to exactly 20KB?
Yes. Our tool uses advanced JPEG quantization and chroma subsampling to reduce even a 5MB photo to exactly 20KB. Signature clarity and face detail are preserved.
What is the SSC CGL photo size requirement?
SSC CGL requires your passport-size photo to be between 20KB and 50KB in JPG/JPEG format. The signature image must be between 10KB and 20KB. Use our tool to hit these targets precisely.
What photo size does UPSC require?
UPSC CSE requires a passport-size photograph (4.5cm x 3.5cm) in JPG format, not exceeding 40KB. Signatures must be in JPG, maximum 20KB. Our 20KB compressor works perfectly for both.
Will the signature stay readable at 20KB?
Yes. We apply a high-contrast filter specifically for signatures, so the ink strokes stay crisp and dark against a white background even at 20KB.
Which format should I use — JPG or PNG?
Use JPG for all Indian government portals. Most exam portals (SSC, UPSC, IBPS, RRB) explicitly require JPG/JPEG format. Our tool automatically outputs a compliant JPG file.
Is my photo safe to upload here?
Completely safe. Your files are processed in temporary memory and automatically deleted within 15 minutes. We never store, view, or share any uploaded images.
What if I need a different size like 10KB or 40KB?
We have dedicated tools for every size. Use our Compress to 10KB tool for digital signatures, or our 40KB compressor for UPSC and passport photos. Links are in the 'You might also need' section below.
Complete Guide: Compress Image to 20KB for Indian Exam Portals
Almost every Indian government recruitment portal — SSC, UPSC, IBPS, SBI, RRB, and state PSCs — requires photos and signatures to be under 20KB. Smartphone cameras produce images of 3MB to 7MB, making this a 150x reduction challenge. Our tool handles this automatically.
Why 20KB is the Magic Number
Government servers process millions of applications simultaneously. A 20KB cap ensures fast uploads even on slow mobile networks (2G/3G) and keeps server storage manageable at scale. The good news: at 20KB, a well-compressed JPG is still perfectly readable by human reviewers.
