What Batch Watermark Applier does, with a checked example

Batch Watermark Applier lets you upload multiple images, position a text or logo watermark across all of them, and download the result as a single ZIP archive. The same settings are applied consistently to every file in the batch. The most common surprise is that the tool does not store or share your images; everything happens in your browser and the watermarked files are returned to you directly. Another frequent misunderstanding is that the watermark is burned into the pixels permanently, so removing it later is not possible.

Worked example

A concrete input and expected output from the current implementation.

Input

Upload 3 photos: photo1.jpg, photo2.png, photo3.jpg. Text watermark: '© 2025 Jane Doe', position: bottom-right, opacity: 70%.

Expected output

A ZIP archive containing three watermarked images. Each image has the text '© 2025 Jane Doe' rendered in the bottom-right corner at 70% opacity.

The tool applies the same watermark settings to every image in the batch, then packages the watermarked files into a ZIP archive for download.

How the result is produced

Uniform watermark placement

You choose a position (top-left, top-right, bottom-left, bottom-right, center, etc.) once, and that position is used on every image regardless of its dimensions or aspect ratio. The same watermark settings, including text, font, and opacity, are applied to every image in the batch.

Batch ZIP download

After processing, the tool compiles all watermarked images into a single ZIP archive. This avoids downloading files one by one. The original images are not modified on your device; the watermarked versions are new files created from the uploads.

Good uses

A photographer wants to put a copyright notice on 200 proofs before sending them to a client, and needs the same watermark position on every shot.
An e-commerce seller has hundreds of product photos and needs to add a store logo to each one before uploading them to a marketplace.
A social media manager needs to add a handle or tagline to a batch of images for a campaign, and wants the same text watermark in the same corner throughout.

Limits and checks

The ZIP download may be large if you upload many high-resolution images. The archive size depends on the original file sizes and how the tool re-encodes the watermarked images, so it is not necessarily equal to the sum of the originals.
Watermark is permanent once applied. The output files contain the watermark pixels, and there is no way to undo it, so keep the original unwatermarked copies if you need them.
If your logo file has a transparent background, that transparency is preserved, but if it has a solid background, that background will appear on your images. Check your logo before uploading.

Common questions

Can I watermark images of different sizes and get the watermark to look the same?

The tool applies the same watermark settings to every image. Because the images may have different sizes, the watermark may appear at different absolute sizes or positions, but the settings you choose are used consistently. You can test with one image first.

Do I need to keep my browser open while processing a large batch?

All processing happens in your browser, so closing the tab or navigating away will stop the process. For a very large batch, you should keep the tab active and wait for the ZIP download to finish. It is also a good idea to use a computer with enough memory.
