When you need a file under 100 KB
100 KB is the most common upload limit on forms. A typical phone photo is 2 to 5 MB, so it needs to be resized as well as compressed. The tool does both automatically.
How the size is reached
The converter tries your chosen quality first. If the file is too big, it searches for the highest quality that still fits. Only if even a low quality is too large does it reduce the width and height, step by step, until the file fits.
To be safe, “100 KB” here means 100,000 bytes, the stricter of the two ways sites count kilobytes, so the file passes either check.
Questions
Are my photos uploaded anywhere?
No. The conversion runs inside your browser on your own device. Your files are never sent to a server, so it also works for private photos and documents.
Why did the dimensions change?
A large photo cannot fit in 100 KB at full resolution without looking blocky. Shrinking the width and height a little keeps it much clearer than crushing the quality.
Can I keep it as PNG?
Yes, choose PNG under More options. PNG cannot lower its quality, so only the dimensions are reduced; JPG almost always looks better at small sizes.
