Image Watermark Tool
Stamp your text or logo onto photos — batch, tiled patterns, no daily cap, no added branding.
Also known as: Photo watermark tool, Watermark maker, Logo watermark generator
How it works
- 1Upload one photo or a whole batch — JPG, PNG, WEBP, and more all work.
- 2Choose text or logo watermark, and fill in your message or upload your logo.
- 3Set opacity, rotation, size, and color, then pick a position from the 3×3 grid or switch to tiled mode.
- 4Check the live preview against your first image — it's the exact result every image in the batch will get.
- 5Watermark the batch and download — one file directly, or a ZIP if you uploaded more than one.
Why use Image Watermark Tool
True batch processing, no daily cap
Watermark 1 photo or 100 in the same pass — no per-day task limit some competing free tools impose.
Tiled pattern mode, free
A repeating, staggered watermark pattern that's genuinely hard to crop out — often a paid-tier feature elsewhere.
Nothing added but your own mark
No upstream logo, link, or branding stamped onto your image alongside your watermark.
Free-form rotation and precise position
Rotate to any angle, not just fixed presets, and place with a 3×3 grid that covers every real placement need.
Remembers your last setup
Watermark settings are saved locally in your browser, so you're not rebuilding text, color, and position every visit.
Nothing uploaded
Every photo is decoded, watermarked, and re-encoded locally on canvas — your images never leave your device.
Who uses Image Watermark Tool
Protecting photography before sharing online
Photographers and artists stamping a copyright mark or studio name across portfolio images before posting.
Branding product photos
Small businesses adding a logo watermark to product shots for a marketplace listing or social post.
Marking draft or confidential images
A rotated "DRAFT" or "CONFIDENTIAL" text watermark across a screenshot or mockup before internal review.
Batch-branding an entire shoot
Apply the same watermark to dozens of photos from one shoot in a single pass instead of one at a time.
About Image Watermark Tool
Most free watermark tools pick one lane: either they're free but capped at a couple of images a day, or they're unlimited but stick their own branding on top of yours, or the tiled/repeated pattern that actually deters someone from cropping your mark out sits behind a paid plan. This tool skips all three trade-offs — batch as many images as you want, nothing added but your own mark, and tiling is a free toggle, not an upsell.
A text watermark supports a custom message, adjustable font size and color, bold weight, opacity, and free-form rotation — not just 0°/45°/90° presets. A logo watermark works the same way: upload a PNG (transparency is preserved) and it scales proportionally as a percentage of the image's shorter side, so the same logo watermark looks right whether it's stamped on a portrait phone photo or a wide landscape shot.
Positioning uses the same 3×3 grid — top/middle/bottom crossed with left/center/right — that every serious watermarking tool converges on, because it covers every placement anyone actually wants without a fiddly free-drag interface to fight with. Switching to tiled mode replaces the single placement with a repeating, row-staggered pattern sized and spaced from the watermark's own dimensions, so it never overlaps itself and never leaves an obvious untouched corner.
Everything — decoding your photo, compositing the watermark, and re-encoding the result — happens on a canvas in your browser. Nothing is uploaded to a server at any point, and your watermark settings (text, color, position, and so on) are saved to your browser's local storage only, purely so returning to the tool doesn't mean rebuilding your setup from scratch.

Pro tips
- Tiled mode with a low opacity (15-25%) is the hardest pattern to crop or clone out — a single corner mark is the easiest to remove.
- A logo with a transparent background (PNG) blends into photos far better than one with a solid white or colored background.
- White or light-colored text reads best on dark photos; switch to a dark color for bright, high-key images.
- Check the live preview at 100% opacity first to confirm placement and size, then lower opacity to the final subtle level.
- Your watermark settings are remembered locally between visits — no need to re-enter your text or logo every time.

Privacy & security
A photo worth protecting with a watermark is usually one you don't want passing through a stranger's server first.
Every watermark is composited locally on canvas — your photos are never uploaded.
Your logo, if you upload one, is processed the same way: entirely in your browser tab.
Watermark settings are saved to your browser's local storage only, never sent anywhere.
No account, email, or login required to watermark a single photo or a full batch.
Frequently asked questions
Is this tool really free with no limits?
Yes — no daily cap, no signup, and no watermark or branding of ours added to your image alongside your own mark.
Does this upload my photos anywhere?
No — every step (decoding, watermarking, re-encoding) happens locally in your browser using canvas. Nothing is sent to a server.
Can I watermark multiple photos at once?
Yes — upload as many as you like and the same watermark settings apply to the whole batch, downloaded as one ZIP file.
What's the difference between a single position and tiled mode?
A single position places one watermark mark (e.g. bottom-right corner). Tiled mode repeats it in a staggered pattern across the entire image, which is much harder for someone to crop or clone out.
Can I use a logo instead of text?
Yes — upload a PNG logo (ideally with a transparent background) and it scales proportionally to a percentage of the image size you choose.
Troubleshooting
My logo watermark looks blocky or pixelated
This usually means the source logo file itself is low-resolution. Upload a higher-resolution version of your logo — the tool scales it down to fit, but it can't add detail that isn't in the original file.
The tiled pattern looks too dense or too sparse
Tile spacing is calculated from your watermark's own size — a larger font size or logo scale produces wider spacing automatically. Adjust size first; spacing follows from it.
My watermark text is cut off or overlapping the image edge
Very long text at a large font size can exceed the available width in corner positions. Shorten the text, reduce the font size, or switch to a center position, which has the most room.
Why didn't my previous settings load?
Settings are saved to your browser's local storage, which is specific to this browser and device — they won't carry over to a different browser, device, or a private/incognito window.
