What Does the Image Watermark Adder Do?
This tool stamps a watermark onto your photos — either custom text (your name, brand or copyright line, with font size and color controls) or a logo image (a transparent PNG works best). Place it in any corner, the center, or tile it in a repeating pattern across the whole image, and dial the opacity from a barely-there 5% to fully solid. The watermarked image downloads immediately and your upload is deleted right after processing.
How to Watermark an Image
- Upload the photo you want to protect (JPG, PNG or WEBP up to 15 MB).
- Choose Text watermark (enter your text, pick size and color) or Logo watermark (upload your logo, set its size relative to the photo).
- Pick a position — bottom-right is the classic — and set the opacity (40–70% deters copying without ruining the photo).
- Click Add Watermark and the finished image downloads automatically.
Watermarking Best Practices
- Semi-transparent beats solid — around 50% opacity marks ownership while keeping the image enjoyable.
- Tile for maximum protection — a repeated diagonal watermark is far harder to crop or clone out than a single corner mark.
- Size proportionally — the tool scales text with image height and logos with image width, so the same settings work on any resolution.
- Keep originals — watermark copies for publishing; archive the clean original.
Photographers protect portfolio previews, shops brand product photos against marketplace scraping, and agencies mark drafts as proofs before payment.
