When 25 KB Is the Limit
25 KB limits are common for signatures and small ID photos on exam forms. The tool lowers the JPG quality step by step until the file fits, and reduces the dimensions only if it has to.
Common Sizes: 10 KB, 20 KB, 25 KB, 30 KB, 40 KB, 50 KB, 100 KB, 200 KB, 300 KB, 500 KB, 1 MB and 2 MB.
How It Works
- Choose or drop a photo.
- Pick a size such as 20 KB, 50 KB or 100 KB, or type your own limit.
- The tool finds the highest quality that fits. Download it.
Frequently Asked Questions
Should I use JPG or PNG for a 25 KB signature?
JPG. It makes a much smaller file for the same signature, so it fits 25 KB easily.
How do I get an exact file size like 20 KB or 50 KB?
Pick the size, or type your own limit. The tool finds the highest quality that fits. If the photo is still too big at the lowest quality, it can reduce the dimensions for you.
Does it work on phones?
Yes. It works in modern mobile browsers, and iPhone HEIC photos open directly.
