How to Resize Image to 20KB for Government Forms

Most Indian government exam portals require passport-size photographs to be in JPEG format under 20KB. Our tool uses the HTML5 Canvas API to iteratively compress your image — trying different quality levels until the file size is at or below your target. Your image is never sent to any server.

• Upload image — Select your JPG, PNG, or WebP photo from your device.
• Set target size — 20KB is pre-selected as the most common govt form requirement.
• Click Compress — The tool runs multiple quality passes using canvas.toBlob() to find the optimal compression.
• Download — Save your compressed JPG image, ready to upload to the govt portal.
