BatchWatermark Image

BatchWatermark Image is a Windows desktop app by 3thousand30 that stamps image and text watermarks onto batches of photos — logos, copyright notices, signatures, and more.

Get it on Microsoft Store

Point it at a folder. Configure your watermark. Click Watermark. Done.

How it works

  1. Select your input folder — pick any folder of JPG, PNG, WebP, or TIFF images
  2. Configure your watermark — overlay a logo image, stamp custom text, or use both at once
  3. Tune with preview — compare original and watermarked versions side-by-side before processing
  4. Watermark — the app composites the watermark onto each image and saves results to a subfolder

Image processing happens locally on your machine. The app may request the Inter UI font from Google Fonts for display consistency when an internet connection is available.

Key features

  • Image watermark — overlay a logo or PNG file at adjustable opacity and scale
  • Text watermark — stamp any text using any installed system font, with color and size control
  • Both at once — combine image and text watermarks in a single pass
  • 9-position grid — place your watermark in any corner, edge, or center
  • Repeat / Tile mode — tile the watermark across the entire image
  • Margin and rotation — fine-tune offset and angle (-180° to 180°)
  • Live preview — watermarked vs original side-by-side before batch processing
  • EXIF metadata — embed Copyright and Author fields into output files
  • Format conversion — output as JPG, PNG, WebP, or keep the original format
  • Filename suffix — optionally append a tag like _wm to output filenames
  • Skip existing files — re-run safely without reprocessing already-watermarked images
  • Batch progress — real-time counter with per-error logging and cancel support
  • Local image processing — all processing happens on your device using Sharp
