How to Increase Image Size in KB

This free online tool lets you increase the file size of a JPG, WebP, HEIC or PNG image to a specific KB value. Enter your required size, select the image, and the tool pads the file to meet the target without changing how the image looks.

Steps to Increase Image File Size

Enter your required image size in KB.
Click Select Images and choose your file.
The tool adds safe padding data to reach your target size.
Click Download button to save the enlarged file.

Does This Reduce Image Quality?

No. The tool never re-encodes or resizes your image. It adds a small block of padding data inside a comment segment that all image viewers and most upload systems ignore, so the visible quality stays exactly the same.

Why Increase an Image's File Size?

Some government portals, exam boards, and job application forms set a minimum file size for uploaded photos or scanned documents. If your image was compressed too much, this tool helps you meet that minimum without editing the photo itself.

Meet minimum file size requirements on government and exam portals.
Fix 'file too small' errors on document upload forms.
Match a required KB range for scanned certificates or ID photos.
Test upload systems that reject unusually small files.
