Compress Image to Exact File Size
Need an image exactly under 200KB for an application form? This tool automatically adjusts compression until your photo hits your exact target file size.
Pass Strict Upload Limits
Government visa applications, university portals, and HR software often have incredibly strict limits: 'Upload photo (Max 150KB)'. Manually saving a JPEG 10 times in Photoshop to guess the correct quality slider is maddening. This tool uses a binary search algorithm. You input your target (e.g., 149KB), and the tool rapidly tests compressions in the background until it hits the exact maximum quality possible under that limit.
Why Use Our Compress Image to Target Size?
- Target Driven: Just type '200KB' and the tool does the math.

Frequently Asked Questions
If the target is mathematically impossible for the image's resolution, the tool will lower the quality to 1% (the lowest possible). It may also prompt you to resize the pixel dimensions.
PNGs are lossless, making exact size targeting difficult. This tool converts the output to an optimized JPEG to guarantee it meets your file size requirement.
