MarkStamp

MarkStamp is a mobile + desktop companion app for bulk adding smart watermarks to photos. Import a folder or select hundreds of images, then automatically place a clean overlay containing date, time, GPS location (city/address), and optional custom text (project name, client, device). MarkStamp reads EXIF metadata to ensure the stamp matches when the photo was taken—not when it was edited—and falls back gracefully when metadata is missing. Users can choose templates (bottom-right, border label, film-style), adjust opacity, font, and size, and export in original quality with fast batch processing. A simple rules engine lets you apply different stamp formats by album, date range, or camera. Designed for proof-of-work, field documentation, real estate, and content creators, MarkStamp makes compliance-friendly, consistent photo labeling painless without needing Photoshop or manual editing.
