FAQ
Does 画像圧縮 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.
