If you share photos or documents online, a watermark is one of the simplest ways to protect your work. It marks the file as yours, discourages people from passing it off as their own, and can quietly advertise your brand every time the file is shared.
When a watermark makes sense
- Photographers sharing proofs or portfolio images.
- Sellers posting product photos that get copied.
- Businesses sending draft documents or proposals.
- Anyone labelling a file as Confidential, Draft or Sample.
How to add one that looks professional
A good watermark is visible but not distracting. Keep it semi-transparent so it does not hide the content, place it where it is hard to crop out, and use a size that reads clearly without dominating the image. For documents, a diagonal watermark across the whole page is the hardest to remove.
Images and PDFs, both covered
Use the Add Watermark to Image tool for photos, where you can set the text, colour, opacity and position over a live preview. For documents, the Watermark PDF tool stamps your text across every page. Both run entirely in your browser, so your files stay private.
For the strongest protection, combine a watermark with a lower-resolution export when sharing previews online. You keep the high-resolution original for paying clients, and the public version is both marked and less useful to copy.
