Increase and Download
Click Increase and Download to save the padded file. The image looks identical, only the KB size is bigger.
Increase Image Size in KB for Government and Job Forms
Some online forms reject an image if its file size is below a set number of kilobytes. Government portals, exam applications, and job sites in India often ask for a photo or document scan of at least 20 KB, 50 KB, or more. This tool raises the file to your exact target without changing how the image looks, so it passes the check on the first try.
It works by adding harmless padding data to the end of the file. The width, height, and picture quality stay exactly the same, only the file size on disk goes up. That saves the trial and error of re-saving or re-exporting an image again and again just to nudge the KB up.
Everything happens in your browser, so the image never leaves your device. Want the full walkthrough with exam-specific KB limits? Read the guide on how to increase image size in KB.

Frequently Asked Questions
Common questions about increasing image file size in KB.
How do I increase the size of an image in KB?
Upload your image, type the target size in KB, and click Increase and Download. The tool pads the file to just above your target. It is free, runs in your browser, and does not change how the image looks.
Why do forms ask for a minimum KB size?
Many government and exam portals set a minimum file size to make sure the uploaded photo or scan has enough data to be readable. If your image is below that size, the form rejects it until you increase it.
Does increasing the KB size lower the image quality?
No. The tool only adds padding data to the file. The pixels, dimensions, and sharpness of the image stay exactly the same, so it looks identical to the original.
Can I increase an image to an exact KB size?
You set the target in KB and the file is padded to just at or above it, so it clears a minimum-size requirement. The target must be larger than the current file size.
Which image formats does it support?
