01 / WHAT

What does the bulk watermark tool add?

A shared text label

Enter a name, credit or short label and apply the same text to all images in your batch.

A visible bottom-right mark

The tool draws white text with a shadow, with text size based on image width. Export the marked images in your chosen format.

A label, not copy protection

The watermark is baked into the output pixels. It does not prevent copying or removal and is not a rights-verification service.

PORTFOLIO IMAGES, WATERMARKEDActual tool outputs

The same “© Studio Collection” text applied to all three images, at the bottom right. Placement and text size follow each image’s dimensions.

02 / WHERE

Where can watermarked images be used?

Portfolio previews

Add a visible studio or creator label to preview images you share with an audience.

Client review folders

Label review copies consistently before sending them to a client or collaborator.

Catalog reference images

Place a short identifying text on image copies used in a product reference collection.

03 / WHY

Why watermark a batch together?

Type the text once

Reuse the same label across a set without editing each file manually.

Keep placement consistent

The tool uses the same bottom-right position and relative sizing rule for each image.

Create separate sharing copies

Keep the source unmarked while producing labeled downloads locally, without uploading the images or signing in.

04 / WHEN

When should you add a text watermark?

You are preparing preview copies

Add a label before sending previews, while retaining clean originals for final delivery.

A collection needs a common credit

Apply a short consistent credit when the images are intended to travel together through a review workflow.

You have finished the crop and resize

Watermark the final composition so later cropping is less likely to cut away the mark. Inspect the text before publishing.

GOOD TO KNOW

Frequently asked questions

Can I upload a logo watermark?

Not yet. This tool currently adds text only.

Can I choose placement or text color?

The current placement is bottom right, with white text and a shadow. Manual positioning, color selection and opacity controls are not available.

Does a watermark protect copyright?

It is a visible label only. The tool does not verify ownership, prevent copying or guarantee that a mark cannot be removed.

Why does long text look smaller?

Text is fitted within the available image width. A short label is easier to read, especially on small output images.

Can I remove the watermark later?

The downloaded watermark is baked into the pixels. Use your untouched original to create a clean version. The free tool does not change that original or upload it.
