Increase Image Size in KB

Make a photo bigger in KB without changing how it looks.

Your files are processed on your device and are never uploaded.

Some upload forms reject a photo not because it is too big, but because it is too small – "minimum file size 20 KB" or "image must be between 50 KB and 200 KB". The ShrinkBee Image Size Increaser fixes that in seconds: it makes your JPG or PNG larger in KB without changing how the picture looks.

Increase Image Size in KB with ShrinkBee

Your photo is not stretched, blurred or re-drawn. Instead, harmless extra data is added inside the file until it reaches the exact size you ask for, so the image stays pixel-for-pixel identical while the file size goes up.

How to Increase Image Size in KB

  1. Choose your image: Click Choose image, drag a photo onto the box, or paste it. JPG and PNG work best.
  2. Enter the new size: Type the size you need and pick KB or MB – for example 50 KB or 1 MB.
  3. Click Increase size: The file is padded to exactly that size in an instant.
  4. Download: Save the new image and upload it to your form.

When Do You Need a Bigger File?

  • Minimum size rules: Exam, recruitment and admission portals often require a photo of at least 10, 20 or 50 KB.
  • Size ranges: Forms that ask for "between 20 KB and 50 KB" fail when a small, tightly compressed photo is under the range.
  • Signatures: A clean signature scan can be only 3–5 KB – much smaller than many portals accept.

Key Features

  • No visible change: The picture itself is untouched – same pixels, same dimensions, same quality.
  • Exact size: Reach any size in KB or MB, not just "a bit bigger".
  • Private: Everything happens in your browser; your image is never uploaded.
  • Free: No sign-up, no watermark and no limit on how many images you resize.
