A visible watermark tells people who took a photo and discourages reuse without credit. Photographers, sellers and creators add a small © line in a corner for portfolios, or a tiled diagonal pattern for proofs and previews. PDFWix Watermark Image stamps your text onto JPG, PNG and WebP photos in your browser, with control over position, size, opacity and light or dark text, and applies it to a whole batch in one go.

PDFWix Watermark Image draws text onto each photo with the canvas 2D API. Font size scales with the photo (a percentage of its shorter side), so the mark looks consistent across images of different resolutions. Opacity is applied with globalAlpha, and a thin contrasting outline keeps the text readable on both light and dark areas. The tiled mode repeats the text at −30° across the whole image. Photos are processed locally and never uploaded.
A corner watermark at 30–50% opacity is the most common choice for portfolios, social media and product photos: it credits you without hiding the image. A centred watermark is harder to crop out and suits photos you share publicly before a sale. A tiled watermark repeats across the whole picture and is the strongest deterrent — ideal for client proofs, real-estate previews and stock samples, where the goal is to show the photo without making it usable. No watermark is impossible to remove, but a larger, tiled or centred mark makes removal far more work than simply asking for permission. Keep your unmarked originals safe and share only the watermarked copies.
