Limits protect memory. Heavy tasks automatically use the server when available.

When should you use this tool?

Reduce a photo’s file size for a form or email attachment. Set a target in KB and inspect the preview before downloading. The achievable size depends on the image content, dimensions and output format, so the target is an attempt rather than a promise.

How to get your result

Adjust quality and the requested size, then check details in the preview. If the target cannot be met, the tool tells you. Try reducing dimensions with Resize image, or lower the quality further only if the image remains readable.

A question?

Can you guarantee a photo under 200 KB?

No. The target depends on the source image. A message appears if it is not reached. Always check the final file size before submitting it.

Are my files uploaded?

Light tasks stay in your browser. Heavy tasks, or local processing lasting over eight seconds, automatically use the server when available. Temporary files are deleted after processing or failure. No account needed.
