What iWatermark is
iWatermark Pro adds visible or hidden marks to photos to identify ownership and help protect copyright. It runs on Android, iOS, macOS, and Windows, with tools for photographers, stock agencies, social sellers, client delivery, portfolio protection, and Creative Commons licensing. Its listed mark types range from text, curved text, banners, logos, vectors, lines, QR codes, and borders to metadata and steganographic marks. Batch processing can handle unlimited photos while preserving color profiles and EXIF/IPTC data. The app accepts RAW, JPG, PNG, TIFF, GIF, DNG, and PSD files, and can output JPG, PNG, TIFF, PSD, BMP, and JPEG 2000. It also resizes and renames images, creates thumbnails, filters inputs, and applies output settings. Metadata support includes XMP, EXIF, IPTC, and Google Search metadata.
