Watermark Image

A watermark will not stop a determined thief, but it does two honest jobs: it marks ownership at a glance, and it makes casual re-use of your product photos and proofs visibly pointless. This tool stamps text or your own logo onto an image — sized, positioned, faded, or tiled — with a live preview so you see exactly what downloads.

How to use Watermark Image

  1. Choose or drop the image you want to mark.
  2. Pick text or image mode and type your text or choose a logo file.
  3. Set size, opacity, and position — or switch on tiling — while watching the live preview.
  4. Download the watermarked result in JPG or PNG.

Supported behavior

  • Text watermarks support size, color, and opacity, placed on a 3 × 3 grid or tiled across the image.
  • Image watermarks accept a PNG, JPG, or WebP logo with its own scale and opacity controls.
  • The preview is the actual full-resolution canvas, so the download matches what you see.

Best for

  • Product photos for marketplaces and social shops.
  • Proof images sent to clients before final delivery.
  • Screenshots and documents that need a visible DRAFT stamp.

Limits

  • A watermark discourages casual re-use; it cannot prevent copying or be removed-proof.
  • Tiled watermarks protect better but distract more — the preview helps you find the balance.
  • Exporting as JPG flattens transparency in the base image, as with any JPEG export.

Privacy notes

  • Selected files stay on your device during processing; nothing is uploaded to a server.
  • Object URLs are revoked when previews or results are replaced.

Watermark Image FAQ

Text or logo watermark — which is better?

A logo looks more professional for brands; text is faster and works for one-off stamps like DRAFT or a name. Both support the same position and opacity controls here.

What opacity should I use?

Between 25% and 50% is the usual range: visible enough to claim the image, light enough not to ruin it. Tiled marks can go lighter, around 15–25%.

Will the watermark reduce my image quality?

The image is re-encoded once at export, like any canvas tool. Choose PNG for a lossless export, or JPG for a smaller file.
