Store description excerpt
Add a watermark to an image or PDF without opening a complicated editor. Watermark One is designed for iPhone and iPad. Choose one image or PDF from Photos or Files, add a text or image watermark, preview the result, then share or save your export. The focused workflow makes it easy to finish wherever you are. KEY FEATURES • Text and image watermarks Enter a copyright notice, signature, brand name, or other custom text. You can also use a logo, signature, or another image as your watermark. • Flexible appearance controls Adjust the font, weight, color, size, opacity, rotation, and margins, then choose from nine convenient positions. • Single or tiled layouts Place one watermark on the canvas or repeat it across the entire image or page. Fine-tune horizontal and vertical spacing for tiled layouts. • Live image and PDF preview Check the result before exporting. For PDFs, move through individual pages to verify watermark placement. • Flexible PDF page selection Apply a watermark to every page, or enter page numbers and ranges to process only the pages you need. • Multiple image export formats Keep the original format or export as JPEG, PNG, HEIC, TIFF, GIF, BMP, JPEG 2000, or AVIF. Adjust output quality for supported lossy formats. • Mobile-friendly export tools Send the finished file with the system share sheet, or save image exports to Photos. Export history stays on the current device so you can preview, share, or delete previous results. IDEAL FOR • Signing photography, illustrations, and design previews • Adding copyright notices, logos, or brand marks to product images • Marking contracts, reference material, and other PDF documents • Adding an ownership overlay before sharing a file PRIVACY FIRST Your image, PDF, and watermark processing happens locally on your iPhone or iPad.
