About Watermark: Sign Every Photo
Photographers, content creators, and small businesses on Mac finally have a watermarking tool that doesn't require a subscription, a cloud account, or a manual-per-image workflow. Watermark: Sign Every Photo imports up to 500 photos, composites your logo or copyright text across every one at full resolution, and delivers the batch to a folder of your choosing — entirely on-device. Batch Up to 500 Images in One Session Drag a folder of photos into the sidebar grid and every image queues immediately: PNG, JPEG, TIFF, and HEIC are accepted at import. An export progress sheet tracks each image as it's composited and saved, then signals when the full batch is complete. Logo Watermark with Opacity and Scale Control Drop any PNG, JPEG, or HEIC logo file into the inspector and it overlays all imported images at configurable opacity (0–100%) and scale (10–80% of source width). Nine named positions — top-left through bottom-right — anchor your logo to the same spot across every photo, ensuring visual consistency across a client gallery or product catalog. Text Watermark with Font, Color, and Rotation Type any copyright notice, signature, or brand line, select a system font from the macOS font library at 12–200pt, define an RGBA color with hex input, set opacity, and rotate the stamp up to ±90° for diagonal or vertical placement. A 200-photo event gallery gets a copyright line on every frame in a single batch — no per-image editing, no editor to open. Drag to Position at 60fps Drag the watermark overlay directly on the preview canvas to any freeform coordinate — the interaction runs at 60fps with compositing deferred until drag ends so the canvas stays responsive. Switch between drag positioning and the nine-preset alignment grid at any time without leaving the inspector. Four Export Formats, Full Source Resolution Every exported file is composited at the original image resolution — not the downscaled preview used for speed. Export as PNG, JPEG with configurable quality, TIFF, or BMP. JPEG exports automatically flatten any transparent alpha channel in your logo file. Private by Design No network calls are made during any session. All compositing runs on-device through CoreImage on your Mac. Images never leave your hard drive — no account required, no upload, no data collection. Built for photographers watermarking client previews, creators protecting portfolio images before publishing, and brands signing product photography before e-commerce upload. One-time purchase, no subscription — watermark your first batch today.
