Watermark Photos in Bulk
If you sell photos, post artwork, or run a small product shop, watermarking is the difference between people sharing your work and people taking it. A logo in the corner is enough for casual theft prevention, and it doubles as free advertising every time the image gets reposted.
Drop in up to 20 images. Choose a logo file or type the watermark text. Pick where it goes — corner positions work best because the eye expects them there and they don't break the photo. Set opacity around 30–50% so the watermark is visible without dominating the image.
The original images stay untouched. You download the watermarked copies as a ZIP if you uploaded several. If you want different watermarks for different sets, run the tool twice — there's no limit on how many times you can use it.
