Questions people ask
Can I compress a PNG to 100KB?
Yes. PNG files are converted to JPG so they can reach 100KB, since PNG cannot be compressed to an exact size.
Can I compress a PDF to 100KB here?
This tool is for images. For PDFs, convert the pages to JPG, compress them, and convert back with JPG to PDF.
Does it work offline?
After the page loads, yes. Everything runs in your browser.
How do I compress a photo to exactly 100KB?
Pick the 100KB target. The tool finds the best quality that fits under 100KB and only shrinks the dimensions if it has to.
Will compressing reduce quality?
Slightly, but at 70–85% quality the difference is hard to see while the file gets much smaller.
