How to add a watermark to an image online

  1. Add your image

    Drop a JPEG, PNG, or WebP into the drop zone, click to browse, or paste from your clipboard.

  2. Type your watermark

  3. Position and style it

    Pick one of nine positions or tile the text diagonally, then set size, opacity, and color.

  4. Download the result

    The preview always shows the final image. Click Download to save it in the same format.

Why use this tool

Nine positions or diagonal tiling

Place the mark in any corner, on any edge, or dead center, or repeat it at 45 degrees across the whole frame.

Size and opacity control

Scale the text from 2 to 15 percent of the image width and fade it from a faint 10 percent to fully opaque.

Automatic contrast color

Auto mode samples the brightness behind the mark and picks white or black so the text stays readable, with a subtle shadow for busy backgrounds.

The preview is the result

Every change redraws the image instantly. What you see on screen is exactly the file you download.

Keeps your format

JPEG in, JPEG out. PNG and WebP keep their format too, and the download adds a -watermarked suffix to the filename.

Private and free

Watermarking runs on your device. Photos are never uploaded, and there is no signup or fee.

About this tool

This tool stamps a line of text over a JPEG, PNG, or WebP image. Drop a photo, type the text, and the preview redraws immediately with the mark in place. Nine anchor positions cover the corners, edges, and center, and a tile toggle repeats the text diagonally at 45 degrees across the whole frame. Size runs from 2 to 15 percent of the image width, opacity from 10 to 100 percent, and the color is white, black, or an automatic choice that samples the brightness behind the mark. A subtle contrasting shadow keeps the text legible on busy backgrounds.

Typical uses: marking proofs before they go to a client, branding product photos for marketplace listings, and deterring casual reuse of images posted publicly. Be honest about that last one, though. A watermark deters, it does not prevent. A determined person can crop out a corner mark or paint over it, which is why tiling exists; text repeated across the frame is far more work to remove than a single line in a corner. For client proofs, a tiled or centered mark at the default 40 percent opacity is usually the right balance between visible and obnoxious.

Everything happens on your device, which matters most when the image is unreleased work; a proof never touches a server on its way to being marked. The download keeps the original format. If the file also needs to be lighter before sending, run it through the image compressor afterwards, and if it should not carry location or device metadata either, the EXIF remover strips that out. To change the dimensions first, start with the image resizer.

Frequently asked questions

Where can I place the watermark?
Anywhere along the edges, in any corner, or dead center: nine anchor positions in total. If a single mark is too easy to crop out, turn on tiling and the text repeats diagonally at 45 degrees across the whole image.
Why is the default opacity 40 percent?
It is the point where the mark reads clearly without wrecking the photo underneath. Push it higher for client proofs you want to be unmistakable, or lower it for a quiet brand mark on finished work.
Does watermarking reduce image quality?
PNG output stays lossless. JPEG and WebP are re-encoded at a high quality setting, so a slight generation loss is possible but rarely visible. Very large images are downscaled to fit browser limits, and the tool tells you when that happens.
Does a watermark stop image theft?
No. It deters casual reuse and makes ownership obvious, but a determined person can crop or edit out a corner mark. Tiled text across the frame is much harder to remove, which is why the tile option exists.
What happens if my text is too long?
The watermark stays on a single line. If it is wider than the image at the chosen size, it is shortened with an ellipsis; reduce the size slider or trim the text to fit more in.
Is my photo uploaded anywhere?
No. Watermarking runs entirely in your browser and the image never leaves your device. That matters when you are marking unreleased or client work.
