🎯 Resize Image in KB
Quick answer
This free tool compresses a JPG or PNG photo to a target file size in kilobytes, which online application forms commonly require (for example "photo must be under 50 KB"). It automatically finds the best quality — and smaller dimensions only if needed — so the result stays under your target.

Frequently asked questions
Why do online forms ask for a photo under 50 KB or 100 KB?
Government, exam and job application portals limit upload sizes to save storage and bandwidth. This tool reduces your photo to exactly that range so the form accepts it.
Will my photo become blurry at a small KB size?
At very small targets like 10–20 KB some softness is unavoidable. The tool first lowers JPEG quality at full size and only shrinks the dimensions when quality alone is not enough, which keeps the result as sharp as possible.
What if the tool cannot reach my target size?
For extremely small targets it returns the smallest file it can achieve and tells you the actual size, so you can decide whether it is close enough for your form.
