About Image text watermark

Overlay semi-transparent text on PNG or JPEG with canvas—position, opacity, and size—local only. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Common mistakes to avoid

  • Expecting tiled or image logos

    This tool overlays text only—not a second image asset.

  • Very long watermark strings

    Long text may overflow small images—keep labels short.
