SSS

Does Image Compressor upload my data?

No. Processing stays in your browser and is not uploaded.

Do I need an account?

No. Open and use — no signup.

How is this different from upload-based tools?

Tools run locally in your browser; content is not sent to our servers for processing.

Are there limits?

Limited by device memory and the browser; very large inputs may slow the page.
