Añade marcas de agua a tus imágenes — gratis

Suelta una o varias imágenes, cambia a la pestaña Texto, escribe el texto de tu marca de agua (©, ™, nombre de marca, etc.) y ajusta la fuente, el color, la posición, la opacidad, la escala y la rotación en tiempo real. La vista previa se actualiza mientras haces los ajustes; cuando estés conforme, pulsa Descargar para una imagen o Descargar todo (ZIP) para todo el lote.

Yes — drop or select dozens of images and the same watermark settings are applied to every one. Output is packaged as a single ZIP so you can save it once and unzip into your delivery folder. Your images are uploaded to our secure server to composite the final watermark and are automatically deleted afterward; we never keep or share them.

Ambas funcionan: las marcas de agua de texto son más rápidas de configurar y fáciles de leer; las marcas de agua con logotipo refuerzan la identidad de tu marca y resultan más profesionales en un portafolio. Para las galerías de clientes, un logotipo de baja opacidad colocado en diagonal sobre la foto evita que las descargas gratuitas socaven tus tarifas de licencia.

Elige entre nueve preajustes de posición (esquinas, bordes, centro) o selecciona «Mosaico (repetir)» para cubrir toda la imagen con un patrón repetido de tu marca de agua. El modo mosaico es la opción más segura contra el robo: quien quisiera usar la imagen tendría que eliminar las marcas de agua de cada región.

Elige un color que contraste (blanco en escenas oscuras, negro en escenas claras) o usa un gris neutro al 30-40 % de opacidad que se lee bien en ambas. El control de opacidad va del 5 % al 100 % en pasos del 5 % para que encuentres el equilibrio justo entre visibilidad y estética.

Las entradas PNG se mantienen como PNG (sin pérdidas); las entradas JPG se recodifican con un 92 % de calidad, algo visualmente indistinguible del original en casi toda la fotografía. Los metadatos EXIF se eliminan en el proceso, lo cual es útil para la privacidad al compartir públicamente.

Yes. The on-screen overlay you see while adjusting sliders is only a browser approximation; the final watermark is composited on our secure servers for pixel-accurate, full-resolution output, and the file is deleted automatically afterward. We never keep or share your images — but if you need a strict never-uploaded guarantee for confidential imagery, use a desktop watermarking tool that runs fully offline.

Sí: poner marca de agua es gratis con una generosa cuota diaria y nunca añadimos nuestro propio logotipo a tu resultado. Poner marca de agua a muchas imágenes a la vez por lotes (por ejemplo, todo un álbum de boda en un solo ZIP) es una función Premium.

No. Esta herramienta añade marcas de agua, no las quita. Aplica tu propia marca de agua de texto o logotipo a las fotos de tu propiedad; no borra ni elimina una marca de agua existente de una imagen.

The Font dropdown offers six typefaces — system-ui, Arial, Georgia, Courier New, Impact and Times New Roman — covering clean sans-serif, classic serif and bold display looks. The separate Bold checkbox thickens whichever font you pick, which helps small watermark text stay legible at low opacity or small scale.

The Scale slider runs from 2% to 40% of the image and sets how large the text or logo renders regardless of the photo's resolution, so the same setting looks consistent across a batch of differently-sized images. Use 8-15% for a discreet corner mark and 25%+ for a bold, hard-to-crop-out logo watermark.

The Rotation slider swings from -90° to 90° and angles your text or logo diagonally across the photo instead of sitting flat. A 30-45° rotation is a common anti-theft trick because it makes the watermark harder to crop out cleanly while still reading naturally left-to-right.

Yes — the Quick text row offers one-click presets including the current year copyright symbol, CONFIDENTIAL, DRAFT, SAMPLE, DO NOT COPY and PREVIEW. Clicking one instantly fills the watermark text field, which you can still edit afterward if you need a variation.

For a subtle brand mark, use Bottom-right position, 10-15% scale, 30-40% opacity and a color that contrasts gently with your typical backgrounds. For strong anti-theft protection, switch Position to Tile, raise opacity to 40-50%, set rotation to around 30-45° and increase scale slightly — this covers the whole frame so no single crop can remove it.

Upload a PNG with a transparent background for the cleanest logo watermark — a logo with a solid white or colored background will render as an opaque block sitting on top of the photo instead of blending in. JPG logos work too, but only if you're fine showing that background color over every photo. Switch to the Logo tab and use the 'Upload logo' file picker; the live preview updates immediately so you can check the look before applying it.

The on-screen preview is an approximate overlay so it can update instantly as you drag sliders; the actual watermark is composited on the server using precise pixel positioning for each image's exact resolution. Position, scale, rotation and opacity all carry over exactly, but minor differences in font rendering or edge anti-aliasing can appear between the browser preview and the final render. If you're watermarking mixed-size images in a batch, check the downloaded ZIP rather than judging the whole set from a single file's preview.

Every photo you add is uploaded to our backend, which composites the text or logo watermark at full resolution and returns a processed file (or a ZIP for a batch) for you to download — it is not rendered entirely client-side with canvas and JSZip. Files are still handled securely and auto-deleted after processing, the same as every other tool on the site; only the live on-screen preview you see while dragging sliders runs locally, as an approximation of the final server-rendered result.
