View all toolsFrequently asked questions about 20KB photos
When do I need a 20KB photo?
Many government exam portals (SSC, UPSC, Banking, Railway) and legacy application systems enforce a strict 20KB limit for profile photos and signatures. This helps reduce server load and ensures fast uploads in areas with slow internet.
Is 20KB enough for ID verification?
Yes, absolutely. A well-compressed 20KB JPEG maintains enough detail for facial recognition and is perfectly acceptable for printing on admit cards. The key is starting with a sharp, well-lit original photo.
Will my photo look blurry at 20KB?
Not if you use our tool. We use smart compression that preserves facial features and text while removing unnecessary image data. Your photo will remain clear at the dimensions typically required for forms (100-150px width).
Can I resize any image format to 20KB?
Yes, we accept JPG, PNG, and WebP formats. The tool will automatically convert your image to optimized JPEG format, which offers the best compression for photos while maintaining good quality.
