Are my files uploaded to a server?

No. Every file you select is processed entirely inside your browser using your device's own memory. Nothing is uploaded, stored or shared, so customer documents never leave your computer or phone.

Is there any limit, watermark or sign-up?

No. The tool is free, unlimited and needs no account. Output files carry no watermark of any kind.

Which format is produced?

JPEG by default because it compresses photographs best; you can also target an exact file size in KB when a portal sets a limit.
