Compress Image to 20KB Online — Free
Compress image to 20KB online — free, no upload, no signup, runs entirely in your browser. Some bank KYC forms, exam portals, and visa applications cap photo uploads at 20KB. This compressor reaches that target by lowering JPEG quality, resizing dimensions, and re-encoding locally with the Canvas API. Drop a photo, watch the live size readout, and stop when you hit 20KB. Most ID-style portrait photos compress to 20KB at 25–35% quality with dimensions around 600px on the longest side. Your image never leaves your device.
