Image Compressor — Compress JPG, PNG & WebP to 20KB, 50KB & 100KB
MakeCard Image Compressor is a precision image optimization tool designed to reduce the file size of JPG, PNG, and WebP images down to exact targets like 20KB, 50KB, 100KB, or 200KB. Online recruitment and government application portals (such as UPSC, SSC, IBPS, State PSCs, NSDL, and UTIITSL) strictly reject passport photos and signature uploads exceeding 20KB or 50KB. This tool features 1-click preset target buttons and an intelligent iterative quality engine that compresses images to your target size while preserving facial features and signature clarity.
How to Use Image Compressor

Review the original image preview along with its file size in KB and dimensions in pixels.
Click a target preset button (e.g. "Target: 20 KB", "Target: 50 KB", or "Target: 100 KB") or adjust the quality slider manually.
Watch the real-time compressed size badge and percentage reduction update instantly.
Click "Download Compressed Image" to save your optimized file.
