## What is TiMark?

TiMark adds professional watermarks to your photos and videos — entirely on your device, with no uploads, no ads, and no compromises.

**Watermark Types**
- Text watermarks with any iOS font, custom size, and full color control
- Logo watermarks using any image from your photo library
- Date and time stamps in seven formats, from short dates to full ISO 8601

**Placement**
- Tile mode: repeat your watermark across the whole image in brick or diagonal patterns, with spacing and rotation control
- Single mode: a multi-layer canvas where each layer can be dragged freely, rotated independently, and snapped to center or other layers

**Style**
- Solid fill with adjustable opacity
- Gradient fill with two-color linear blending
- Drop shadow with configurable offset, blur, and color
- Stroke/outline with configurable width and color

**Video Support**
- Watermark videos in MOV or MP4 using H.265 or H.264
- Preserve the original audio track
- Dynamic watermarks bring your overlay to life with smooth floating motion (Smart Drift) or corner-hopping anti-crop protection (Corner Hop)

**Invisible Watermark**
- Embed a hidden message into image pixels using a state-of-the-art on-device deep learning model
- Adversarial training makes the watermark imperceptible yet robust — surviving cropping, rotation, compression, and combined attacks
- Reed-Solomon error correction protects the payload for reliable extraction
- Detect and extract hidden messages from any image, with a confidence score

**Batch Processing**
- Watermark up to 50 photos and videos at once with the same design
- Cancel mid-batch and retry failed items individually
- Share all results together

**Templates**
- Save your complete watermark configuration — text, fonts, colors, effects, layers, output settings — as a named template
- Apply any saved template with a single tap

**Metadata**
- Preserve original EXIF, IPTC, and GPS data through export
- Embed your own copyright notice and usage note, written to standard IPTC and TIFF fields
- Full metadata inspector: view camera model, lens, location, date taken, and a complete key-value dump of every embedded field

**Export**
- PNG, JPEG, or HEIC output
- Adjustable JPEG/HEIC compression quality
- Resize by max dimension (with quick presets) or by percentage

**Gemini Watermark Removal**
- Remove Google Gemini's built-in watermark from original Gemini images using mathematically accurate reverse alpha blending — no AI model required

**Live Preview**
- See exactly how your watermark looks before exporting
- Tap to expand full-screen on iPhone, or use the side-by-side layout on iPad and landscape

All processing happens on your device. Your images and videos never leave your phone.
