Reduce JPG and JPEG images toward a 100KB limit directly in your browser for website
uploads, CMS media libraries, portfolio pages, and general-purpose sharing.
This page uses automatic target-size compression instead of a manual quality slider,
so the tool can search for the closest practical result for each image.
The tool first checks whether your original JPG is already under 100KB. If it is, the
image stays unchanged. Otherwise, the compressor runs repeated JPEG quality attempts
from the untouched source bytes until it finds the closest practical match.
Quality vs. Dimensions
For 100KB targets, many images can stay at their original dimensions. When a file still
remains above the target at very low quality, the tool can resize from the original pixels
and retry instead of repeatedly compressing a prior output.
Frequently Asked Questions
Can every JPG reach exactly 100KB?
No. Some images are too detailed to land on an exact byte count. The tool works
toward the closest useful result and favors a file at or below 100KB when possible.
Does this page upload my image?
No. Compression runs locally in your browser and image data is not sent to a server.
What happens if my image is already below 100KB?
The original JPG is kept unchanged and you can download it without recompression.
Will image quality change?
It can. A 100KB target often preserves good detail, but heavily detailed photos may
still need stronger compression or smaller dimensions to get close to the target.
