Add a text or logo watermark to any photo directly in your browser. Drag to position it anywhere on the image, choose a font, color, size, and rotation for text watermarks, or upload your own logo and scale it to fit. Adjust opacity and add a drop shadow so your mark stays visible on both light and dark backgrounds.
Watermarking protects your photos, graphics, and designs from unauthorized use and helps establish ownership before sharing work online, in a portfolio, or on social media. Photographers use it to brand proofs before a client pays for full-resolution files. Designers use it to label drafts as work-in-progress. Online sellers use it to discourage image theft on marketplace listings.
Choose between a single watermark placed exactly where you want it, or a repeating tiled pattern that covers the entire image — much harder to crop out than a single corner mark. Nine preset anchor points (corners, edges, and center) make quick placement easy, or simply click and drag on the live preview for pixel-perfect control.
Everything happens locally using the Canvas API. Your original photo and your logo file are never uploaded to a server, so there's no privacy concern and no waiting on file transfers — large batches of edits run instantly even on a slow connection.
How to Use Watermark Tool
Upload the photo you want to watermark (PNG, JPEG, or WebP).
Choose Text or Logo as the watermark type, then enter your text or upload a logo image.
Drag the watermark on the preview to position it, or click a corner/edge anchor for quick placement. Adjust size, rotation, opacity, and color to taste.
Optionally enable Tile pattern to repeat the watermark across the whole image, then download the result.
Frequently Asked Questions
Can I use my own logo as a watermark?
Yes — switch to Logo mode and upload any PNG, JPEG, or WebP file. PNG with a transparent background works best since it blends naturally into the photo.
Does my photo get uploaded anywhere?
No — both the photo and the logo are processed entirely in your browser using the Canvas API. Nothing is ever sent to a server, so your files stay completely private.
Can I watermark many photos at once?
This tool processes one image at a time so you can fine-tune placement for each photo. For a fully automated batch workflow, consider scripting with a library like Sharp or ImageMagick.
How do I make the watermark harder to remove?
Enable the Tile pattern option to repeat the watermark across the entire image rather than placing it in a single corner. A tiled watermark is significantly harder to crop or clone out.
What's the best opacity for a watermark?
30–60% opacity is usually enough to deter unauthorized use while staying unobtrusive. Increase it for proofs you want clearly marked, or lower it for a subtle brand mark in the corner.
Can I rotate the watermark diagonally?
Yes — use the Rotation slider to angle text or a logo anywhere from -180° to 180°. A diagonal watermark across the center is a common style for proofs and drafts.
What image formats are supported for output?
You can export as PNG (supports transparency, larger file size) or JPEG (smaller file size, no transparency). PNG is recommended when your source image has transparent areas.
Will the watermark show up well on both light and dark photos?
Enable the drop shadow option, which adds subtle contrast behind the text or logo so it stays visible regardless of what's behind it in the photo.
