What does a bulk image watermark tool do?
A bulk image watermark tool puts your text or logo on a whole batch of photos together, so each picture carries the same watermark before it is shared. Rather than adding a watermark to every image manually, you load a folder, set up the watermark once and the tool applies that exact design across the batch. All of it happens locally in your browser and the results land in one ZIP, so you can watermark hundreds of high-resolution photos within seconds.
A watermark guards your work and strengthens your brand. A text version can show copyright details or your studio's name, a logo can place a transparent PNG badge on every shot, and a tiled pattern covers the frame so screenshots are hard to reuse. Position, size and opacity controls let you keep the mark discreet or make it bold. Our free online tool keeps your images private — nothing uploaded, no account and no cap on how many you watermark. Since the entire set is processed in one pass, protecting a full shoot or product catalogue takes one click rather than an afternoon of editing, and your watermark sits in precisely the same spot on every image.

Download the ZIP

When bulk watermarking pays off
Guard and brand every image you publish.
Protect product photos
Put your brand on product photos so rivals cannot reuse them in their own listings.
Brand your images
Add a logo or handle to each image so your brand goes wherever it is shared online.
Protect proofs and previews
Watermark client proofs and samples so they can be reviewed without handing over the final files.
Copyright before posting
Stamp a © line across an entire gallery in one batch before it goes live.
Text, logo or tiled — which watermark suits you?
Choose the style that matches how much protection you need.
Text watermark
Quick and adaptable — type a brand, handle or © line and tuck it into a corner.
Logo watermark
Add your logo for a clean, on-brand watermark on each image.
Tiled watermark

How to watermark images in bulk well
Guard your work without spoiling the picture.
Keep opacity subtle
An opacity of 40–60% protects the picture while shoppers can still see the product clearly.
Tile it to beat cropping
A lone corner watermark is easy to crop off — tile it over the image when protection really matters.
Mind the contrast
Use a pale watermark on dark photos and a dark one on bright photos so it stays legible.
Bulk image watermark questions
Is it genuinely free?
Yes. The bulk image watermark tool is free with no sign-up and no account, and you can watermark as many images as you like.
Do my images get uploaded somewhere?
No. Everything happens locally in your browser, so your photos and logo are never sent anywhere and never leave your computer.
Can I add my own logo?
Yes — switch to logo mode and add your logo file (a transparent PNG gives the best result). It is placed on every image at whatever size, position and opacity you set.
Can I use a text watermark instead?
Yes — type anything you like, such as a brand name, a social handle or a © line, and put it wherever you want with full control of size and opacity.
Can the watermark repeat across the image?
Yes — switch tiling on and the watermark repeats over the entire image, so nobody can just crop it away.
Where can the watermark go?
In any of nine preset spots — the corners, the edges or dead centre — or tiled across the whole picture.
Does a watermark reduce image quality?
No — the watermark is layered over your picture and saved at the quality you pick, so the photo itself stays crisp.
Is it possible to watermark hundreds of images together?
Yes. Load a whole folder, and one identical watermark goes onto every image before they download together as a ZIP.
Which formats can I save to?
Leave the files in their original format, or save the watermarked images as JPG, PNG or WebP; JPG and WebP also let you choose how much to compress.
Is there anything to install?
No. The bulk image watermark tool runs in any current browser — no software, no account.
