Photo Ma Ma1.5.0 - App Store

Protect Your Photos and Prove Your Ownership

This app is a powerful, free utility designed for photo lovers and hobbyists who want to mark, brand, and prove ownership of their photos before sharing them online. Whether you're posting to social media, sending photos to friends, or building your own personal collection, you stay in control of how your work is credited.

Key Features:

- Custom Visible Watermarks: Create and save your own text watermark designs. Overlay custom text directly onto any photo to claim visible credit for your work.

- Invisible Ownership Mark: Embed an imperceptible mark inside your photo using established digital watermarking techniques (spatial and frequency-domain embedding). This lets you later verify that a photo is yours - even after it's been shared or re-shared - without altering how the image looks.

- Durable, Compression-Resistant Marking: Choose the embedding method that best matches how you're sharing: lossless PNG (LSB) for archival-quality files, or optimized JPEG (DWT) for everyday sharing.

- High-Compression Export: A DCT-optimized output format designed to keep your ownership watermark intact even after messaging and social apps recompress your images during sharing.

- Full Customization: Adjust transparency, size, and position of your visible watermark to match your exact style.

- 100% On-Device Processing: Your photos never leave your device. All watermarking happens entirely offline - nothing is uploaded, stored, or shared.

Protect your creative work, prove your ownership, and share your photos with confidence.
