Compress Image to 20KB
Compress JPG or PNG images to 20KB free online — no upload, no signup. Perfect for exam form photo uploads with strict size limits.
When You Need an Image Under 20KB
The 20KB photo requirement appears most often on government and examination portals. Online application systems for public-sector jobs, university entrance registrations, and visa services frequently reject any photo larger than 20 kilobytes — and their built-in error messages rarely explain how to fix it.
The trick to hitting 20KB is combining dimension reduction with quality compression. A full-resolution phone photo is 3–8MB; no quality setting alone brings that to 20KB while staying viewable. This tool automatically balances both: it scales the image down to sensible dimensions and applies JPEG compression until the file fits under your target.
Because everything runs locally in your browser, your identity photo, signature scan, or document image is never transmitted anywhere — a genuine privacy advantage over upload-based compressors when handling personal identification files.
