Image Resize to KB の使い方
Upload any image file (JPEG, PNG, WebP) and set your desired target file size in kilobytes. The tool intelligently compresses your image using an iterative binary search algorithm that adjusts quality and dimensions to reach your target size. Perfect for meeting upload requirements for government forms, job applications, or websites with strict file size limits. The compression happens entirely in your browser—your images never leave your device.
Set your target size
Enter your desired file size in KB using the input field or quick-select buttons (50KB, 100KB, 200KB, etc.).
Upload your image
Drag and drop an image onto the upload area, or click to browse for a file from your computer.
Wait for compression
The tool automatically processes your image, trying different quality levels and dimensions to reach your target size.
