Getting a photo under 20 KB
20 KB is a common limit for signatures and small ID photos. A typical phone photo is several megabytes, so it needs both smaller dimensions and stronger compression. Enter the width and height your form asks for first, then the tool reduces JPG quality step by step until the file fits under 20 KB.
If the form asks for a range such as 10–20 KB, set the upper limit: the result comes out as close under it as the photo allows.
Common sizes: 10 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
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.
