Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely in your web browser. Your files never leave your device, which makes it safe for private documents.
How do I reduce an image to under 100 KB?
Lower the quality, choose WEBP, and set a max width such as 1200 px. Check the size shown after compressing and adjust.
