100% private: processed on your device, nothing is uploaded.
How it works
- Choose or drag your image into the box above. The limit is already set to 20 KB.
- We try different quality levels and, if necessary, slightly smaller dimensions.
- Download your image: at most 20 KB whenever that is technically possible.
When do you need an image of 20 KB?
A 20 KB limit is typical for online exam, recruitment and government application portals, which often ask for a scanned signature of 10–20 KB and a passport-style photo of 20–50 KB. At 20 KB a signature stays crisp, and a portrait of around 300 pixels wide is still clear on screen.
How we get to 20 KB
We keep the original dimensions and lower the quality only as far as needed. Only if 20 KB cannot be reached that way is the image scaled down a little, because a smaller sharp photo looks better than a large blurry one.
Frequently asked questions
Will my photo still look good at 20 KB?
On screen, yes, at the sizes these portals ask for. We lower the JPG quality first and only then make the image smaller; a portrait of about 250–350 pixels wide usually fits in 20 KB and stays clear. It is not enough to print large, so keep your original.
The portal also asks for exact pixel dimensions. What now?
Many portals specify both, for example “200×230 pixels, 20–50 KB”. Resize or crop the image to those dimensions first, then compress it to 20 KB here. Smaller dimensions also make it easier to reach the size without visible quality loss.
Will my image be exactly 20 KB?
It will be at most 20 KB, usually slightly below. We count 1 KB as 1000 bytes, so the file also passes upload checks that count 1 KB as 1024 bytes.
