How to Increase Image Size in KB Without Losing Quality

You took a perfectly good photo, resized it to the right dimensions, but now the form says 'file size too small — minimum 20 KB required'. Frustrating. Here's why it happens and how to fix it without ruining your photo.

Why Do Forms Require Minimum KB?

Exam authorities set minimum file sizes to ensure photos are clear enough to print on admit cards and use for identity verification. A 5 KB image at 200×230px would be extremely blurry when printed. The minimum KB ensures reasonable JPEG quality.

3 Methods to Increase KB

Method 1: Increase JPEG Quality

The simplest approach. When you export a JPEG at 100% quality instead of 70%, the file size increases significantly. Our KB Increaser tool does this automatically — it re-encodes your image at maximum quality.

Method 2: Slight Upscale

If max quality still isn't enough, the tool slightly increases the image resolution (invisible to the eye) which adds more pixel data. A 200×230 image scaled to 220×253 then saved at high quality will be larger in KB.

Method 3: Metadata Padding (Last Resort)

For extreme cases, invisible metadata (JPEG comments) can be added to the file. This adds bytes without changing the image at all. The photo looks identical — the file just has extra non-visible data. Most exam forms accept this without issue.

Step-by-Step: Using the KB Increaser Tool

1. 1Go to photosure.app/tools/increase-image-size
2. 2Upload your image (JPG, PNG, or WebP)
3. 3Set your target KB (e.g., 30 KB for SSC, 25 KB for IBPS)
4. 4Click 'Increase' — processing happens in your browser
5. 5Download the result — check the KB in file properties to confirm
