Increase image size in KB
Some portals reject photos that are too small, for example when the file must be between 100KB and 200KB. This tool saves the JPG or PNG again at a higher quality setting to raise the file size towards the KB value you enter, without changing how the picture looks.
How to use this tool
- Upload the image that is too small.
- Enter the size you need in KB, such as 100, 200 or 500.
- Download the larger file.
Frequently asked questions
How do I increase a photo from 20KB to 100KB?
Upload the photo, set the target size to 100 KB and download the new file. A photo with very few pixels may not reach a high target, so upscale or resize it to a larger pixel size first.
Does increasing the KB improve quality?
No. It makes the file larger so it passes the minimum size check. To make a photo look sharper, use the Photo Enhancer tool.
Are my photos uploaded anywhere?
No. The tool runs in your browser, so the image stays on your phone or computer.
