Add Watermark to Photos Online Free

Baked in, not tagged on

This watermark is painted into the pixels on a canvas — not metadata, not an XMP comment in the file. That distinction matters: EXIF and XMP watermarks vanish the moment someone re-saves, crops or screenshots the image. A baked-in mark survives all three, which is exactly why it is irreversible — there is no legitimate "remove" step afterwards. Our export passes through one honest constraint: photos are downscaled to fit a 1600 px canvas — for a 24 MP phone shot, that is a real cap, not a footnote — so your download is not a full-resolution original. Nothing is stamped until you press Apply, and the preview canvas shows exactly what ships.

And a note on scope: this tool stamps text only — no logo upload, no tiled/repeating pattern, one image per pass. Positions are the four corners plus center; JPEG output re-encodes at quality 0.92 (fine, but a real generation loss against your original); PNG output stays lossless. If you needed a scattered all-over pattern, this is not that tool.

• Opacity sweet spot — 60–70%: readable enough to attribute, light enough that the photo still works. Below 30% the mark is decoration; at 100% it insults the viewer.
• Tiled vs corner — corner marks claim provenance; a center stamp at 60–70% is what actually deters cropping. There is no built-in repeat mode here.
• Contrast beats size — white text vanishes on white skies; choose the color against the busiest background region you expect.
• PNG vs JPEG — PNG for sharp text edges and transparency; JPEG only when file size matters.
• Honest limit — a determined scraper crops or clones any visible watermark. It is attribution and friction, not DRM.
