Will the image quality suffer after compression?

A smart algorithm preserves as much quality as possible at your chosen quality level. At 70% quality most people cannot tell the difference from the original.

Is there a file size limit?

You can upload images up to 50MB. Larger files may take a few seconds to process depending on your device.

Is my image uploaded to a server?

No. All compression happens in your browser. Your image is never uploaded to any server.

Do I need to sign up?

No. The image compressor is completely free with no registration or watermarks required.
