What this tool does
- Batch processing — drop in as many images as you like and watermark them all with one set of settings, then download them together as a ZIP
- Text and logo together — turn on a text watermark, a logo watermark, or both at once, each with its own independent styling, size, opacity and position
- Drag to position, or snap to a corner — drag each watermark exactly where you want it on a live preview, or use the 9-point grid to snap it to a corner, edge or the center with an adjustable margin
- Tiled / repeated mode — repeat either watermark diagonally across the entire image, like a stock-photo preview, so it can't be cropped or cloned out easily
- Opacity & rotation control per watermark — dial in how subtle or bold each watermark looks, and rotate it to any angle, independently of the other
- Scales with image size — text and logo size are set as a percentage of each image's width, so batches of different-sized photos get a consistent-looking watermark
- Format conversion — export as PNG, JPEG or WebP, or keep each image's original format
- Live preview — every image in the gallery updates instantly as you tweak settings, before you download anything
Why watermark an image
- Protect photos and designs you share online from being used without credit
- Brand product photos, portfolio shots or social media posts with your logo
- Mark drafts or proofs as "sample" or "not final" before sending them to a client
- Deter unauthorized reuse of stock photos or client previews with a tiled watermark
Text vs. logo watermarks — or both
A text watermark is the fastest way to add a copyright line, website URL or brand name — it needs no extra files and scales cleanly to any size. A logo watermark looks more polished for branding since it reproduces your exact mark; a PNG with a transparent background works best so only the logo shape shows up, not a colored box around it. Turn on both at once — for example a logo mark in one corner and a text credit in another — since each has its own independent opacity, position, rotation and tiling controls.
Frequently asked questions
Are my images or logo uploaded anywhere?
No — the watermark is drawn directly onto each image using the canvas element inside your browser. Neither your photos nor your logo file are ever sent to a server.
Can I watermark multiple photos at once?
Yes — drop in as many images as you like and the same watermark settings are applied to all of them. Download them individually or together as a ZIP file.
Can I use a logo and text watermark at the same time?
Yes — turn on "Text watermark" and "Logo watermark" together and both are drawn on your images at once, each with its own independent size, opacity, rotation and position, so you can place a logo in one corner and a text credit in another.
Can I repeat the watermark across the whole image?
Yes — turn on "Repeat watermark across image" to tile it diagonally across the entire photo, which makes it much harder to crop or clone out, similar to stock photo previews.
Will the watermark size stay consistent across differently sized images?
Yes — text and logo size are set as a percentage of each image's width, so the watermark scales proportionally whether you're batch-processing a tiny thumbnail or a full-resolution photo.
