How to use the compress to target size
- Add your images.
- Enter the maximum size in KB.
- We lower quality first, then dimensions only if needed.
- Check the result — we clearly flag any file that couldn't fit.
How we hit the target
We search for the highest quality that fits under your limit. If even low quality is too big, we shrink the dimensions step by step. We stop before the image becomes unusably small and tell you honestly if the target wasn't reached.
Output format
Results are saved as JPG (best compatibility) or WebP (smaller). Transparent areas become white in JPG.
