Image Watermark Guide: Add Text Watermarks to Images Online for Free
Learn how to use AIBox to batch add text watermarks to photos, product images and documents with adjustable opacity, angle, font size and density.
Adding watermarks to images is a common way to mark ownership, protect content, brand product photos and label social media posts. The AIBox watermark tool supports batch text watermarks so every image keeps a consistent look.
When to Use Watermarks
Watermarks are useful when publishing portfolio images, course materials, pricing sheets, product photos or event shots. Batch watermarking is especially helpful for processing an entire set of assets at once, keeping style consistent across every file.
What to Prepare
Decide on your watermark text first — brand name, account handle, contact info or a copyright notice. After uploading images, choose a color and opacity that suit the image brightness, then adjust angle, font size and density so the watermark is visible without covering key content.
Why Use an Online Tool
Professional editors are powerful but heavy for a quick batch watermark job. An online watermark tool puts all the essential parameters on one page so you can preview results and generate output immediately — ideal for lightweight, everyday tasks.
