Add text or image watermarks

How to add a watermark

1. Choose one or more static JPEG, PNG, WebP, AVIF or uncompressed BMP images, a folder or a ZIP archive.
2. Enter text or choose a logo. Set size, position, opacity and angle; compare the effect with the original.
3. Choose the output format, process the images and download individual results or the ZIP.

A watermark that fits each image

Choose one of nine positions, set the margin and angle, or tile the mark across the image. Text size and logo width are percentages of each image’s shorter side. A mark that would cross the edges is reduced to fit.

Text supports up to 200 characters and four lines, with a color, bold weight and optional black outline. The three font families use system fonts; no fonts or files are sent elsewhere.

Preview and batch export

The effect preview is reduced for responsiveness. Processing uses the oriented original dimensions. Changing options removes old results, and each image is processed independently.

Use a static PNG with transparency for a logo without a rectangular background. JPEG and WebP logos are also accepted within the same 15 MB and 16 million pixel limits as source images.

Process a folder or ZIP locally

Import up to 50 images, 100 MB of input and 100 million pixels in total. Each image must stay within 15 MB, 16 million pixels and 8192 pixels per side. Folder imports include nested folders; non-image files are skipped. All files stay in this page’s memory.

Apply the same settings and process images one at a time. Failed images are listed separately and do not block other files. Preview individual results or download a ZIP with preserved folder paths and unique output names. Encrypted ZIPs, ZIP64 and nested archives are unsupported. Changing settings clears old results; cancelling keeps already completed results.
