Fine-Tune Between 48KB (Under 50KB) and 55KB (Above 50KB)

Check your official notification wording carefully: if the form says **"20 KB to 50 KB"**, type `45` in Target KB (or pick `Min–Max Range: 20 to 50 KB`) so the file stays strictly ≤ 50.0 KB while comfortably clearing 20 KB.

If the form says **"Minimum 50 KB to 100 KB"** (such as IBPS handwritten declarations or UKVI 50 KB minimums), type `60` in Target KB so every byte sits safely above the 50 KB floor!

1-KB Precision Dial

Set 45 KB, 50 KB, or 60 KB with single-kilobyte precision in Stage 3.

Preserves Exact Pixels

Your 350×450 px or 413×531 px dimensions remain untouched unless you enable Stage 2.

Frequently asked questions

Why did my photo shrink to 15KB after cropping on my phone?
Mobile gallery editors re-save cropped photos at ~75% JPEG quality, and smooth white backgrounds contain very few high-frequency DCT coefficients—dropping file size under 20 KB.
Should I pick 45KB or 50KB for SSC and UPSC?
For SSC/UPSC (20–50 KB limit), targeting 45 KB or using our Resize Image 20KB to 50KB range preset guarantees your file is well above 20 KB and strictly under the 50.0 KB ceiling.
What if I need 50KB to 100KB for an IBPS handwritten declaration?
Simply type 65 in the Custom KB input above (keeping Exact mode selected) to generate a ~65 KB JPG right in the middle of the 50–100 KB window.
Does increasing KB add visible noise or artifacts?
Zero artifacts! PixelKit uses higher luminance/chrominance precision plus standard non-visual JPEG metadata padding.
