Questions people ask
How do I compress an image to 100KB?
Upload your image, click the ≤ 100 KB target button, and the tool automatically lowers the quality until the file fits under 100KB. Then hit download.
Are my images uploaded to a server?
No. All compression runs inside your browser using the HTML canvas. Nothing is uploaded, so it's completely private and works even offline.
Which format gives the smallest file?
WebP is usually 25–35% smaller than JPG at the same quality. Use JPG for maximum compatibility, PNG only when you need transparency or lossless output.
Will compressing reduce image quality?
Slightly — that's how size is saved. At 70–85% quality most photos look identical to the eye while being a fraction of the original size.
