FAQ

Is this image compressor really free and private?

Yes. Compression runs entirely in your browser using the canvas engine on your own device. The image is never uploaded to a server, there are no limits, no watermarks, and no signup.

How do I compress an image to a specific size like 300 KB?

Switch to Target size mode and enter the size in KB. The tool searches for the highest JPEG quality that fits under your target, so a LinkedIn or job-portal upload limit is one click away.

Will compressing reduce my image quality?

JPEG compression is lossy, but at 75–85% quality the difference is invisible for social posts. Preview updates live so you can judge before downloading.
