Add a watermark to your photos - a discreet corner mark, a centred logo or a repeating tiled pattern - at the opacity and placement you choose, with the picture itself left untouched underneath.
How the photo watermark maker works
Upload the photo, give the exact text or describe the mark, and say where it should sit and how visible it should be. The tool applies it at your chosen scale and opacity, tuned so it stays legible without swamping the image, leaving the photograph unchanged beneath. Check the spelling in the result, rerun to adjust, then download.
Tips for the best results
Low opacity in a corner suits portfolios; a tiled diagonal pattern deters reuse on proofs and previews. Keep the wording short so the letterforms stay clean, and always proofread the output. Match the mark's tone to the image - light on dark photos, dark on light ones - rather than always using white.
