How to batch watermark photos in 3 steps
- 1
Upload your batch
Drag and drop up to 20 JPG, PNG or WebP photos, or click to pick them from your device. The tool loads them instantly without uploading.
- 2
Set the watermark once
Type your text, choose size, color and opacity, then drag the mark onto the preview. The exact same style is applied to every photo in the batch.
- 3
Download the ZIP
Click download. All watermarked photos are processed at full resolution and packed into one convenient ZIP file that saves to your device.
Why batch watermarking saves time
If you shoot a session, list ten products or publish a set of portfolio shots, adding a watermark to each one by hand is slow. Every file needs the same text, the same opacity, the same position. Doing it once and applying it to the whole set is the fastest way to stay consistent.
This tool keeps the watermark proportional to each image. Size is set as a percentage of width, so a portrait photo and a landscape photo in the same batch look right without you nudging each one. A tiled pattern is also available when a single mark is not enough to protect the image from being cropped.
Features of this bulk watermarker
Save hours of manual work
Instead of opening an editor for 20 photos one by one, set your watermark once and apply it to the whole batch instantly. Perfect for photographers and busy sellers.
Consistent branding
All photos get the exact same text, size, and position. This consistency is crucial for portfolios, client proofs, and e-commerce product catalogs.
Live drag preview
See exactly how the watermark looks on the actual photo before processing. Drag it anywhere with your mouse or finger, and the coordinates apply to the whole batch.
Private, runs in your browser
Your photos are not uploaded to a server. The watermark is drawn locally in your browser using the HTML5 Canvas API, keeping your client work completely private.
Tips for a consistent batch
- 1
Check a portrait and a landscape photo
Because the size is relative to the image width, a 5% watermark looks right on both orientations. Scan the thumbnails before you download to make sure.
- 2
Keep opacity between 30% and 60%
This is readable without hiding the subject. If you are sending low-res previews to a client, 30% opacity is usually enough to protect the image from theft.
- 3
Use tiled mode for public galleries
If you are uploading a hundred photos to a public gallery, a tiled mark is much harder to crop out than a single corner mark. Switch to Tiled in the Position menu.
- 4
Place it over a detailed area
A watermark in a plain sky or a solid background is easy to remove. Placing the text near the subject or over a textured area makes removal much harder.
- 5
Watermark copies, keep originals
Always keep your original, unmarked photos safe in a separate folder and publish only the watermarked copies. The tool never overwrites your original files.

Bulk watermark FAQ
How many photos can I watermark at once?
Up to 20 images per batch. If you have more, simply watermark them in groups of 20; the settings stay the same so the final look will be completely consistent.
Does batch watermarking give every photo the exact same mark?
Yes. The text, size, color, opacity, rotation and position are identical for the whole batch. Size is set as a percentage of image width, so it scales properly on both portrait and landscape photos.
How are the batched images downloaded?
Two or more images are packed into one ZIP file for easy downloading. If you only upload a single image, it downloads directly as a JPG or PNG without zipping.
Does bulk watermarking upload my photos to a server?
No. Every image is processed in your browser with the HTML5 Canvas API. Nothing is sent to our servers, so your client work and private photos stay 100% on your device.
Can I batch watermark product photos for my shop?
Yes, this is one of the most popular use cases. Upload your listing photos, set your shop name as the watermark, and download the ZIP. It is a common workflow for online sellers on Shopify, Etsy, and Amazon.
What image formats work with this tool?
JPG, PNG and WebP input. JPG and WebP images are saved as high-quality JPG files; PNG images stay PNG so transparency is kept. You can adjust the JPG quality if needed.
Will batching reduce the image quality?
No. Every photo is redrawn at its original resolution with the watermark on top. Saving as JPG applies the usual JPG compression, but the dimensions and clarity of the original image are preserved.
Can I use a logo image instead of text?
Not yet. This tool currently supports text watermarks only. You can type your brand name, website, or copyright symbol as the text.
Is it free to use?
Yes. No sign-up, no watermark added by us, and no per-image charge. It is completely free for personal and commercial use.
Privacy note
The watermarking happens on your device. Your photos are read by your browser, drawn on a canvas and saved back to your device. They are not sent to ToolDeck servers. See our Privacy Policy for details.
