The Problem: You are trying to upload a photo or signature to a website (like a job application, college admission, or government portal), but it rejects your file saying: "File size must be between 20KB and 50KB."
Most photos taken on modern phones are huge—often 3MB to 5MB (that's 3000KB to 5000KB!). Reducing them to 50KB seems impossible without making them look like a blurry mess. But it is possible if you use the right technique.
Websites set these strict limits to save server space. When millions of people upload files, every kilobyte counts. They don't need a high-resolution print-quality photo; they just need a small, clear image for identification.
Most online compressors ask you to choose a "Quality Percentage" (like 70% or 50%). This is a guessing game. You might pick 50% quality and end up with a 120KB file—still too big. Then you try 10% and it looks terrible.
The better way is to specify your Target File Size directly. You tell the tool "I want 50KB," and it calculates the exact compression needed to hit that number.
Use our free tool EasyImageCR.in. It processes images locally in your browser, so your private photos are never uploaded to a server.
If compressing to 50KB makes your image look pixelated or blurry, it means your image dimensions (width x height) are too large.
The Fix: Resize the dimensions first.
No matter the limit, the "Target Size" feature on EasyImageCR handles it instantly.
