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

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