How to use

Purpose

Add text or image watermarks to one or many photos at once, all locally. Customize position (9-point grid or free placement), rotation, opacity, font, color, shadow, and stroke. Apply the same watermark to a whole batch with one click — perfect for protecting photography portfolios, branding social posts, marking confidential business documents, or stamping store logos on product photography.

Steps

  1. Upload one or more images
  2. Pick watermark type: text / image / tiled (repeats across the whole image)
  3. For text: type your watermark, pick a font, size, color, shadow, and stroke
  4. For image: upload your PNG logo or signature (transparent background recommended)
  5. Position via 9-grid presets or free drag; adjust rotation and opacity (0-100%)
  6. Toggle 'apply to all' to watermark the entire batch with one click
  7. Download single files or a ZIP

FAQ

Can I tile the watermark across the whole image?
Yes. Tiled mode repeats the watermark across the entire canvas — common for photographer portfolio protection or 'CONFIDENTIAL' across documents. Spacing and rotation adjustable.
Can I watermark many photos with the same mark?
Yes — this is the primary use case. Configure once, toggle 'apply to all' and a hundred photos get the identical watermark in seconds.
Can I upload my own logo as a watermark?
Yes — a PNG with transparency is ideal. Square or thin horizontal logos position cleanest on most photos.
Will adding a watermark hurt quality?
The composite step is pixel-perfect. Quality loss only comes from JPEG re-encoding at export; choose PNG for lossless output.
Where can I place the watermark?
9-point grid (corners, edges, center) for one-click placement, or free-drag for pixel-precise positioning.
