Frequently Asked Questions
Can I compress an image to exactly 20KB?
The tool aims for 20KB or slightly below it. The final size can vary by a few bytes because JPG, PNG, and WebP encode each image differently.
What if my image is already under 20KB?
You may not need to compress it. Compare the original and result sizes before downloading so you do not reduce quality without a reason.
How does the image compressor reach a low KB limit?
It first adjusts image quality. If that is not enough and resizing is enabled, it also reduces pixel dimensions while keeping the aspect ratio.
Will text and signatures stay readable at 20KB?
Very low file limits can reduce detail. Start with a tightly cropped image, use JPG or WebP, and check the downloaded result at full size before submitting it.
Are my images uploaded to a server?
No. The image is read, compressed, and downloaded in your browser. It is not sent to our server.
