How to Add a Text Watermark to Images Online

Add text watermarks in your browser. Choose a position or tiled layout, adjust advanced settings and check readability before processing a batch.

A text watermark can label a sample, identify a creator or mark an image as a draft. ConverterTo places text directly into the image pixels and saves a new copy. It does not add an editable text layer.

Add a watermark step by step

  1. Open Image Watermark.
  2. Select JPEG, PNG, WebP or BMP images. Multiple files are supported.
  3. Replace the default watermark text with your own.
  4. Choose the center, a corner or the repeated tile layout.
  5. Open Advanced settings to adjust opacity, font size and color if needed.
  6. Start conversion, download the output and open it to check placement and readability.

The same text and settings apply to every image in a batch. Test one image first, especially when the batch mixes different dimensions. Processing takes place in your browser; image files are not sent to a conversion server.

Available settings

SettingCurrent choices
PositionCenter, four corners, or Tile (Repeat)
Opacity5–100%; default 30%
Font size12–200 pixels; default 48
ColorWhite, black, red or gray

The text is drawn in a bold sans-serif font. There is no font picker, logo upload, free-position dragging or live placement preview. Inspect the downloaded copy to judge the result.

A fixed font size can look small on a very large photo and oversized on a small image. Long text may run beyond an edge. Try shorter text, another position or a different font size before processing the whole batch.

What changes in the output?

The text becomes part of the pixels. Keep the original because this tool cannot remove the watermark later or reopen it as an editable object. JPEG and WebP are re-encoded, so this is not a lossless edit. Original metadata is not preserved by the image-rebuilding workflow.

A visible watermark is a label, not an access-control mechanism: it cannot prevent someone from copying, cropping or editing an image.

Common problems

Text is hard to see: try another color or higher opacity, then check a new output.

The browser slows down: process fewer images at once. Large images use more memory even if their compressed files look small.

Need a smaller file afterward: try Image Compression, compare quality and size, and keep the uncompressed original.
