常见问题
Is 添加水印 free?
Yes. 添加水印 is completely free with no sign-up, no watermark and no daily limit. There is no paid tier — every tool on iAdorePDF is free to use as often as you like.
Is 添加水印 safe and private?
Yes. 添加水印 runs entirely inside your browser, so your file is never uploaded to any server. Nothing leaves your device, which makes it safe for confidential documents.
Do I need to install any software?
No. 添加水印 works in any modern browser — Chrome, Safari, Firefox or Edge. There is nothing to download and no account to create.
Does 添加水印 work on a phone?
Yes. 添加水印 is built mobile-first and works on iPhone and Android exactly as it does on a computer, straight from the browser.
Can I control how the watermark looks?
Yes. Set your own text, then adjust size, opacity, rotation and position so the mark is visible without hiding the content underneath. It is applied to every page at once.
How do I use 添加水印?
Open the page, drop your file into the upload box (or tap Select file), choose your options, then press the start button. Your result downloads straight to your device.
Is there a file size limit?
There is no server limit because the work happens on your own device. The practical ceiling is your device memory; files up to about 100 MB are comfortable on most phones and much larger on a computer.
