Image Watermark

Add watermarks to images client-side

Use this image watermark tool to add text watermark or logo watermark overlays before publishing product photos, screenshots, portfolio images, and social posts. Choose a single position or tile the watermark across the image, then download the result from your browser.

Common image watermark workflows

• Add watermark text to ecommerce product photos, marketplace previews, or catalog drafts.
• Use tile mode when you want repeated watermark coverage across the whole image.
• Upload a logo image as the watermark and adjust size, opacity, position, rotation, and gap.
• Apply watermarks client-side without sending source images to a remote editor.

Image watermark FAQ

Can I add a text watermark?

Yes. Enter custom text, then adjust font size, font family, color, opacity, position, rotation, and tiling.

Can I use a logo as the watermark?

Yes. Switch to image watermark mode, upload a logo, and adjust the watermark size and placement.

Can I tile the watermark across the image?

Yes. Tile mode repeats the watermark across the image and lets you control the gap and offset.

Are images uploaded?

No. Watermark rendering runs client-side in your browser, and BaseToolbox does not upload or store your images.
