Increase Image Size in KB
Some application portals reject photos that are too small, for example 'between 20KB and 50KB'. Set the minimum and this tool makes your image just big enough: first by saving at a higher JPEG quality, then by enlarging the dimensions slightly, and only as a last resort by adding harmless padding. Runs entirely in your browser.

- Set the minimum KB: Type the minimum size from your form (e.g. 20KB) or tap a quick size.

Frequently Asked Questions
How do I increase an image's size in KB?
Drop the image and enter the minimum KB your form needs. The tool raises the JPEG quality until the file is just above that size; if that isn't enough, it enlarges the image slightly.
Why would I need a bigger file?
Exam, job and government portals often set a range such as 20–50KB for photos and 10–20KB for signatures. Images below the minimum are rejected.
Does increasing the KB improve image quality?
Saving at a higher quality keeps more detail, but it can't add detail that was never captured. If the original is blurry, start from a better scan or photo.
What is the padding option?
If quality and size increases still can't reach the target, the tool adds a JPEG comment block. The picture is untouched and every viewer ignores it, but the file meets the byte count.
