Photo Watermark Tool

It is a deterrent and attribution signal, not a substitute for copyright registration or licensing contracts. Jurisdiction matters: commercial reuse may still happen; combine watermarks with proper terms of use and takedown processes for stolen work.

Yes—inpainting, crops, and contrast tricks can hide simple text, especially on uniform backgrounds. Position near important detail (without ruining the art) and keep originals offline; never publish the only high-res master if theft is a concern.

Re-saving JPEG would introduce another lossy generation on top of your watermark strokes. PNG keeps the composited pixels crisp, including alpha if your source had transparency (text still flattens atop that layer).

Font size is in CSS pixels relative to the bitmap height. For very large photos, raise the pixel size until the text reads well at the intended viewing resolution; preview on a phone if social delivery is the goal.

The canvas `fillText` path uses basic shaping; complex scripts and color emoji may render differently than in native OS text fields. For marketing-critical Arabic/Indic layouts, verify the PNG visually before publishing.

This page processes one file at a time for simplicity and privacy. For hundreds of assets, scripting with ImageMagick, sharp, or desktop Lightroom export presets will beat manual repetition.
