When 40 KB Is the Limit
Some application portals cap photos at 40 KB. The tool finds the highest quality that fits, so the photo is never compressed more than it needs to be.
For the sharpest result, first set the pixel size your form asks for. A smaller picture leaves more of the 40 KB for detail.
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
My form says 20–40 KB. What do I do?
Choose Between Two Sizes under File Size and enter 20 and 40. The tool keeps the file inside that range.
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.
