When to use Compress Image to 100 KB
Use this page for an upload limit of 100 KB. The converter searches quality settings and picks the best result it can fit under 100 KB without changing dimensions. PNG input becomes JPG, with transparent pixels filled white.
Quality and file size
The target is a maximum, not a quality guarantee. Lower quality can blur fine texture or create blocks around edges. PNG transparency is lost when it is encoded as JPG. Detailed images may remain over the limit even at the lowest setting; resize the image if needed.
Frequently asked questions
Can every image fit under 100 KB?
No. Detailed images may stay above the limit or need resizing; stronger compression also reduces visible quality.
Does compression change dimensions?
No. It changes JPG or WebP quality only. Resize first if smaller dimensions are acceptable.
What happens to PNG input?
PNG files are encoded as JPG so the size target can be adjusted with quality settings. Transparent pixels become white.
Are files uploaded?
No. Compression runs locally in this browser tab.
