Image Compressor

What Does This Tool Do?

This free online tool compresses your image to approximately 400KB without requiring any software installation. Simply upload your JPG, PNG, or WebP image, and the compressor will reduce the file size using smart quality adjustment (around 77% JPEG quality) to target 400KB. The process runs entirely in your browser — your files are never uploaded to any server.

Why Compress Images to 400KB?

• Social media uploads — platforms like WhatsApp and Instagram prefer smaller files.
• Form uploads — government portals and job applications often cap image size at 400KB.
