Watermark Tool
Add a text watermark to an image directly in your browser.
Local image watermarking
Create a watermarked image.
Choose an image, edit the watermark text, adjust placement, opacity, and size, then export a PNG. Your image stays on your device.
When should you watermark an image?
Watermarks help mark ownership, prepare drafts, label previews, and share images while keeping brand or source context visible.
Keep watermarks readable without covering important image details. For privacy-sensitive photos, remove metadata before publishing.
