What it is
iWatermark Pro adds visible and invisible watermarks to photos to help protect copyright. Its mark types include text, curved text, banners, logos or bitmaps, vector and line marks, QR codes, borders, metadata, and steganographic watermarks. Batch processing can handle an unlimited number of photos while preserving color profiles and EXIF/IPTC data. The app can also resize and rename images, create thumbnails, filter inputs by size, resolution, or format, and apply output settings. Supported inputs include RAW, JPG, PNG, TIFF, GIF, DNG, and PSD; output formats include JPG, PNG, TIFF, PSD, BMP, and JPEG 2000. Metadata support covers XMP, EXIF, IPTC, and Google Search metadata, including adding or removing metadata and using tags as watermarks. The Mac edition supports AppleScript, and the Windows version has an Explorer context-menu extension. Trial software is listed for Mac, Windows, iOS, and Android, with no duration stated. The Mac product page does not show a purchase price, although the manual says $30. The Mac version does not support WebP.
