Image Watermark

Posting client galleries or product shots with nothing on them is an open invitation for quiet reuse. This tool lets you add watermark to image files right in the browser: type your studio name or handle, tune the size and opacity, and stamp it in a corner or tile it diagonally across the whole frame. Photographers watermark photo online proofs before a gallery goes out; sellers mark product photos before they hit marketplaces where listings get scraped. A live preview shows exactly how strong the mark reads against your shot, and bulk mode runs an entire folder and returns a ZIP with every file marked identically.

Bulk supported. Drop multiple files and they'll be processed in a queue with a single ZIP download. Same settings apply to every file.

How to use

01

Add your photos

Drop in one image to work with the live preview, or select a whole shoot at once. Bulk mode kicks in automatically when you add multiple files.

02

Write and tune the mark

Type your name or brand in the Watermark text field, set a Color, drag Size between 12 and 200 pixels, and lower Opacity until the mark is visible without smothering the photo.

03

Place it and export

Choose a corner, edge, or center from the Position dropdown, or tick Tile diagonally for proof-style coverage. Click Apply watermark, then download the file or the full ZIP.

Why Image Watermark

Common questions

What opacity works best for a photo watermark?
For a single corner mark, 30 to 50 percent is usually enough to read without wrecking the image. Tiled watermarks can drop lower, around 20 to 35 percent, because repetition does the protecting. The slider here runs from 10 to 100, so you can test against your actual photo in the preview.
Can I put logo on photo files with this image watermark tool?
The watermark here is text-based, so there's no image upload for a graphic logo. If your logo is a wordmark, typing the same name gets you most of the way. For a pictorial logo you'd composite it in an image editor, then use this tool for the text layer.
Where should the watermark sit so it can't be cropped away?
Corners are the easiest to crop out. If theft is a real concern, use middle center or tick Tile diagonally, which repeats the mark across the entire frame at an angle. Tiling is the standard approach for client proofs precisely because no crop survives it.
Does watermarking recompress my photos?
Yes, the image is redrawn on a canvas and re-encoded in its original format, so a JPG goes through one more compression pass. At normal quality settings the difference isn't visible, but always keep your clean originals and treat watermarked exports as distribution copies.
How do I add watermark to image batches from a full shoot?
Select all the files at once. Each one is processed with the same text, color, size, opacity, and position, renamed with a -watermarked suffix, and bundled into watermarked-images.zip. Two hundred proofs take a single click and a short wait.
Is a watermark real legal protection for my images?
It's a deterrent and an attribution signal, not enforcement. Copyright exists whether or not you watermark photo online copies, but a visible mark discourages casual reuse and makes ownership obvious in screenshots. Keep originals with intact metadata as your actual evidence trail.
Why does my white watermark vanish on bright photos?
White text at partial opacity has almost no contrast against sky, snow, or white studio backgrounds. Switch the Color to a dark gray or black for bright images, raise the opacity slightly, or move the Position to a darker region of the frame.
Is this online watermark maker free, and does it need an account?
It's free with no signup and no export cap. As an online watermark maker it runs entirely on a canvas in your browser, so you can make watermark online as many times as you want and nothing about your photos gets sent to a server.
How do I watermark image online without installing any software?
Open the page, drop a photo, type your mark, and press Apply watermark. That's the whole loop to watermark image online, and you add watermark online right in the tab, since the rendering happens locally rather than on some upload server.
Can I add watermark to jpg and jpeg files without changing the format?
Yes. The tool re-encodes each file in the format it arrived in, so when you watermark jpg photos they come back as JPGs, not PNGs. Both add watermark to jpg and add watermark to jpeg work the same way, and the only trade is the one extra compression pass any JPG edit involves.
What's the quickest way to put watermark on image and picture files for a portfolio?
Drop the shots in, set your text and a low opacity, and pick a corner from the Position dropdown. You can put watermark on image files one at a time with the live preview, or put watermark on picture batches all at once, which is the usual move before a portfolio goes public.
Does this let me watermark pictures and pics for a proof set?
That's a core use. Load the proofs, tick Tile diagonally, and every frame gets a repeated mark. It handles a folder of watermark pictures in one run, so marking a batch of watermark pics for client review takes a single click and a short wait.
Can I add text watermark to pictures like a studio name across a photograph?
Yes, the mark is text-based, so type your studio name and it renders in bold sans-serif over the shot. You can add text watermark to pictures at any size from 12 to 200 pixels, which is enough to run a bold photograph watermark corner to corner when you tile it.
What do searches like convert image to watermark actually get you here?
A bit of a naming mix-up, so here's the honest version. You don't turn a photo into a watermark file; you stamp a text mark on top of it. So convert image to watermark, convert picture to watermark, and change picture to watermark all land on the same job on this page, which is adding a readable mark to a photo you keep.
How do I create watermark image online for product shots before a marketplace listing?
Type your shop name, set a color that reads against the product, and place it where a scraper can't easily crop it. Sellers create watermark image online copies precisely because listings get lifted, and the watermark add in image step here takes seconds per shot.
Is there a cap when I watermark photos online in one session?
No. You can watermark photos online with no file counter and no daily limit, and it stays watermark photos online free the whole time. The only real ceiling is your own machine's memory on very large batches.
As a bulk image watermark tool, does every photo get an identical mark?
Yes. As a bulk image watermark tool it applies the same text, color, size, opacity, and position to every file you add, then bundles them into watermarked-images.zip. That consistency is the point, so a whole shoot carries one uniform mark rather than slightly different ones.
Is this a full photo editor watermark feature or a single-purpose tool?
It's focused on watermarking rather than a full editor. If you were expecting a photo editor watermark panel with layers and filters, pair this with the Add Text to Image and Image Filters tools instead. Keeping it single-purpose is what makes the batch output predictable.
How do I download watermark images once the mark is applied?
Press Apply watermark and a single file downloads on its own with a -watermarked suffix. To download watermark images in bulk, add several files first and they arrive together as one ZIP, so you're not saving them one by one.
Why watermark images and add watermark to proofs before a gallery goes out?
It's about deterrence and credit, not lockdown. When you watermark images headed for a public gallery, casual reuse gets harder and your name travels with any screenshot. Photographers add watermark stamps to proofs for exactly this reason, then hand over clean originals only once a client pays.
