Add text and batch watermark, all in one
Stamp your name, shop title or copyright notice onto photos right in the browser. Type the text, choose its size, colour, opacity, angle and position, and place it once in a corner or tile it across the whole image. A single photo is a live preview; switch to batch mode to apply the identical stamp to a whole folder.
The watermark is drawn with the local Canvas engine, so your photos are never uploaded and the export carries no watermark other than the one you designed.
A watermark solves two different jobs: branding, where a small logo or shop name sits unobtrusively in a corner, and protection, where repeated low-opacity text covers the image so it cannot be cropped out and reused. The same panel handles both, by switching between a single position and tiled repeat.
The watermark text is a free field. Font size runs from 12 to 120 pixels and defaults to 36; the text renders bold in the browser’s default sans-serif face (there is no font-file upload, so it matches the system font on your device). Choose a text colour and, optionally, an outline colour; the outline is a 2-pixel stroke drawn under the fill.
A 3-by-3 grid places the stamp at nine slots, centred by default, with a 30-pixel margin near the edges. Opacity runs from 10% to 100% and defaults to 70% — low enough to read as a stamp, high enough to hold up on a pale background. Rotation sweeps from minus 90 to plus 90 degrees, which is useful for a diagonal corner stamp.
Turn on “tile mode” to repeat the text across the image on a diagonal grid: rows are spaced by roughly the font size plus an 80-pixel gap, and columns by the measured text width plus 100 pixels. Tiling is the strongest protection because removing the stamp would leave a visible patch across the whole frame; pair it with lower opacity so the image underneath still shows.
Single mode gives a live canvas preview and lets you use the nine-position grid and outline toggle. Batch mode accepts many files and applies the stamp to each; to keep batch output predictable the stamp is drawn centred on every photo, and the outline option is not re-applied in batch. Each batch file downloads separately on a short delay rather than as a ZIP, so leave the folder open until all downloads finish.
Stamping is pure Canvas drawing in your browser tab; the source photo is never transmitted. There is no account and no queue. Because the tool exports PNG, any transparency in your source is preserved; if you need a smaller JPEG after stamping, compress the result with the image compressor.
Yes. Switch to the batch tab, select several files, set the text and style once, and every photo gets the stamp. Batch output places the watermark centrally on each image and downloads as separate PNG files.
Turn on tiled repeat; the text is repeated across the whole image on a diagonal grid. Lower the opacity to around 30–50% so the stamp protects the photo without hiding it, and add an outline for legibility on busy backgrounds.
The stamp is drawn bold in the browser’s sans-serif font. Size runs 12–120 px, text colour and optional outline colour are full colour pickers, and rotation spans minus 90 to plus 90 degrees. You cannot upload a custom font file.
To keep batch results consistent across photos of different shapes, batch mode stamps every file centrally rather than applying the nine-position grid. Use single mode when a specific corner placement matters.
No. The stamp is painted on a local Canvas in your tab and the file never leaves your device. The only watermark on the export is the one you designed.
