Image Size Inflater

Tool Guide

Tool Overview

The online image size-increaser can increase an image's file size without changing its original dimensions, enlarging an image to a specified file size in one click, such as increasing a 100 KB image to 5 MB.

Note: this tool increases the image's file size without changing the image quality; the core idea is to pad the image with useless data to reach the specified size.

Many situations require increasing an image's file size, such as registration photo processing, where many platforms have explicit file-size requirements for ID photos and reject registration if the size is below the specified value.

In the software testing industry, functional testing of a system's file upload often requires files of various sizes; this tool can quickly generate images of a specified size to quickly obtain test material.

How to Use

Click to upload or drag the image to process onto the page, set the target image file size, and click the "Increase Image Size" button to complete the size increase. Once processing is complete, click the download button or the preview image to save the image locally.
