Common questions

Can I watermark multiple images at once?

Yes. Upload multiple images, configure text, position, opacity, and export format, then run the batch.

Where should I place a watermark?

Place it near the subject without covering key information, and use moderate opacity to reduce easy cropping.

Are images uploaded while adding watermarks?

No. Watermark rendering happens locally in the browser, which is useful for unpublished assets and rights labeling.
