FAQ
Does Watermark PDF upload my data?
Most main-site tools process input locally in the browser. Website diagnostic tools that request public URLs explain the remote request scope in the tool UI.
Can I use Watermark PDF on mobile?
Tool pages use responsive layouts for phone, tablet, and desktop. Large file processing still depends on device memory and browser limits.
Can I download or copy the Watermark PDF result?
Migrated tools provide copy, download, or direct result views in the output area depending on the tool type.
