InkStamp: Photo Watermark

InkStamp is a private photo watermarking app for creators, online sellers, photographers, students, and anyone who wants their photos to travel with a signature — not with tracking. Add text, signatures, logos, copyright notes, retro stamp effects, or invisible watermarks without sending your images to a server. Every edit is processed on your iPhone or iPad. KEY FEATURES • Photo watermark editor Layer text, signatures, logos, dates, copyright labels, and retro stamp effects on a single photo. Drag to position, rotate up to 360°, tune opacity, and preview in real time. • Batch watermark export Import a full shoot, pick one watermark style, preview every image, then export the whole batch in one flow. Perfect for shops, portfolios, class photos, and client previews. • Invisible watermark Embed a mark that is imperceptible in normal viewing but can be verified later with the in-app detector. Useful for proving ownership of a leaked shot. • Templates for repeat use Save your go-to stamp as a template so every export stays on-brand without re-adjusting rotation, opacity, or position. • Private by design No account. No ads. No analytics. Photos are processed on-device and are not uploaded by InkStamp. • Retro look that sets your photos apart Cream paper, coral ink, mint accents, classic stamp motifs. Your watermark signals craftsmanship, not stock filters. WHY INKSTAMP IS DIFFERENT 1. The invisible-watermark detector is built in, not sold as a separate app. You can verify your mark later, even on a screenshot a friend took. 2. Batch mode treats every batch as one trip: you preview, adjust, and export all images together, so every photo carries the same signature. 3. Everything happens on-device. InkStamp never uploads the photos you stamp.
