Watermark tips

- A small corner watermark at 50–70% opacity is the least distracting for portfolios.
- Use white text on dark photos and black text on bright ones.
Frequently asked questions
Are my images uploaded to a server?
No. ToolSmith processes every image locally in your browser. Your files are never uploaded, stored or seen by anyone — you can even disconnect from the internet after the page loads and the tool keeps working.
Can I add a logo instead of text?
This tool adds text watermarks. Tip: the © symbol plus your name or website is the most common and effective choice.
Is the original photo changed?
No. Your original file is untouched — you download a new, watermarked copy.
Does it work on my phone?
Yes. It works in any modern browser on Windows, macOS, Linux, iPhone, iPad and Android — there is no app to install.
