FAQ
Frequently asked questions
What is a good JPEG quality for 100 KB?
It depends on the image. A simple portrait may fit at 90% quality; a busy landscape may need 60–70%. The tool works it out per photo.
Can I convert PNG to a 100 KB JPEG here?
Yes. PNG files are converted to JPG and compressed under 100 KB. Transparent areas become white.
Does it reduce the resolution?
Only when quality alone isn't enough. You'll see the new dimensions next to the file if they change.
Why is my result smaller than 100 KB?
If the photo reaches top quality below 100 KB, there's no benefit in making it bigger, so it stays smaller.
